+# ExoPlayer WorkManager extension #
+
+This extension provides a Scheduler implementation which uses [Android Arch WorkManager][].
+
+[Android Arch WorkManager]: https://developer.android.com/topic/libraries/architecture/workmanager.html
+
+## Getting the extension ##
+
+The easiest way to use the extension is to add it as a gradle dependency:
+
+```gradle
+implementation 'com.google.android.exoplayer:extension-workmanager:2.X.X'
+```
+
+where `2.X.X` is the version, which must match the version of the ExoPlayer
+library being used.
+
+Alternatively, you can clone the ExoPlayer repository and depend on the module
+locally. Instructions for doing this can be found in ExoPlayer's
+[top level README][].
+
+[top level README]: https://github.com/google/ExoPlayer/blob/release-v2/README.md

Subject: [PATCH 007/807] Fix two ad insertion related bugs in
 DefaultPlaybackSessionManager.

1. A content session after an ad has been played was not re-marked as active,
   leading to new ad session being marked as active too early.
2. Switching from content to post-roll ended the content session because
   the return value of getAdGroupTimeUs of C.TIME_END_OF_SOURCE was not
   handled. Using the nextAdGroupIndex instead.

Subject: [PATCH 008/807] Add option to clear all downloads.

Adding an explicit option to clear all downloads prevents repeated database
access in a loop when trying to delete all downloads.

However, we still create an arbitrary number of parallel Task threads for this
and seperate callbacks for each download.

Subject: [PATCH 010/807] Ensure messages get deleted if they throw an
 exception.

If a PlayerMessage throws an exception, it is currently not deleted from the
list of pending messages. This may be problematic as the list of pending
messages is kept when the player is retried without reset and the message is
sent again in such a case.

Subject: [PATCH 021/807] Fix Javadoc generation.

Accessing task providers (like javaCompileProvider) at sync time is not
possible. That's why the source sets of all generateJavadoc tasks is empty.

The set of source directories can also be accessed directly through the static
sourceSets field. Combining these allows to statically provide the relevant
source files to the javadoc task without needing to access the run-time task
provider.

Subject: [PATCH 030/807] Ignore empty timelines in ImaAdsLoader.

We previously only checked whether the reason for the timeline change is
RESET which indicates an empty timeline. Change this to an explicit check
for empty timelines to also ignore empty media or intermittent timeline
changes to an empty timeline which are not marked as RESET.

Subject: [PATCH 036/807] Use versioned manifest in all Robolectric tests.

We are currently defaulting to targetSdk=1 as no targetSdk is specified. Only
tests which explicitly ask for another SDK use another test SDK. With the
versioned manifest, all tests run using the targetSDK by default.

Subject: [PATCH 042/807] Update surface directly from SphericalSurfaceView

The SurfaceListener just sets the surface on the VideoComponent, but
SphericalSurfaceView already accesses the VideoComponent directly so it seems
simpler to update the surface directly.

Subject: [PATCH 061/807] Remove contentTypePredicate from DataSource
 constructors

The only known use case for contentTypePredicate is to catch
the case when a paywall web page is returned via a DataSource,
rather than the data that was being requested. These days streaming
providers should be using HTTPS, where this problem does not exist.
Devices have also gotten a lot better at showing their own
notifications when paywalls are detected, which largely mitigates
the need for the app to show a more optimal error message or
redirect the user to a browser.

It therefore makes sense to deprioritize this feature. In
particular by removing the arg from constructors, where nearly
all applications are probably passing null.

Subject: [PATCH 068/807] Fix VP9 build setup

Update configuration script to use an external build, so we can remove use of
isysroot which is broken in the latest NDK r19c. Also switch from gnustl_static
to c++_static so that ndk-build with NDK r19c succeeds.

Issue: #5922

Subject: [PATCH 071/807] Fix video size reporting in surface YUV mode

In surface YUV output mode the width/height fields of the VpxOutputBuffer were
never populated. Fix this by adding a new method to set the width/height and
calling it from JNI like we do for GL YUV mode.

Subject: [PATCH 073/807] Migrate org.mockito.Matchers#any* to
 org.mockito.ArgumentMatchers

The former is deprecated and replaced by the latter in Mockito 2. However, there is a
functional difference: ArgumentMatchers will reject `null` and check the type
if the matcher specified a type (e.g. `any(Class)` or `anyInt()`). `any()` will
remain to accept anything.

Subject: [PATCH 077/807] SimpleCache: Tweak comments related to blocking

"Write case, lock not available" was a bit confusing. When the
content is not cached and the lock is held, it's neither a read
or a write case. It's a "can't do anything" case. When blocking,
it may subsequently turn into either a read or a write.

Subject: [PATCH 078/807] Fix CacheUtil.cache() use too much data

cache() opens all connections with unset length to avoid position errors.
This makes more data then needed to be downloading by the underlying
network stack.

This fix makes makes it open connections for only required length.

Issue:#5927

Subject: [PATCH 081/807] Handle gzip in DefaultHttpDataSource.

Setting the requested encoding in all cases ensures we receive the relevant
response headers indicating whether gzip was used. Doing that allows to
detect the content length in cases where gzip was requested, but the server
replied with uncompressed content.

 ### dev-v2 (not yet released) ###
 
+* Add `PlaybackStatsListener` to collect `PlaybackStats` for playbacks analysis
+  and analytics reporting (TODO: link to developer guide page/blog post).
 * Add basic DRM support to the Cast demo app.
 * Add `ResolvingDataSource` for just-in-time resolution of `DataSpec`s
   ([#5779](https://github.com/google/ExoPlayer/issues/5779)).

Subject: [PATCH 088/807] Make parallel adaptive track selection more robust.

Using parallel adaptation for Formats without bitrate information currently
causes an exception. Handle this gracefully and also cases where all formats
have the same bitrate.

Subject: [PATCH 095/807] Display last frame when seeking to end of stream.

We currently don't display the last frame because the seek time is behind the
last frame's timestamps and it's thus marked as decodeOnly.

This case can be detected by checking whether all data sent to the codec is
marked as decodeOnly at the time we read the end of stream signal. If so, we
can re-enable the last frame. This should work for almost all cases because the
end-of-stream signal is read in the same feedInputBuffer loop as the last
frame and we therefore haven't released the last frame buffer yet.

Issue:#2568

Subject: [PATCH 099/807] Don't throw DecoderQueryException from
 getCodecMaxSize

It's only thrown in an edge case on API level 20 and below. If it
is thrown it causes playback failure when playback could succeed,
by throwing up through configureCodec.

It seems better just to catch the exception and have the codec be
configured using the format's own width and height.

Subject: [PATCH 106/807] Wrap MediaCodec exceptions in DecoderException and
 report as renderer error.

We currently report MediaCodec exceptions as unexpected exceptions instead of
as renderer error. All such exceptions are now wrapped in a new DecoderException
to allow adding more details to the exception.

Subject: [PATCH 118/807] Gracefully handle revoked ACCESS_NETWORK_STATE
 permission.

This permission has normal access right and can't be revoked by the user.
However, an app can choose to revoke it when using ExoPlayer, e.g. if
no network is required and the app doesn't want to list this permission.

Support this use case by gracefully catching the exception in the relevant
places.

Subject: [PATCH 120/807] Prevent negative total buffered duration at the point
 where it is calculated.

In some edge cases the renderer position may be slightly ahead of the
buffered position and the total buffered duration is thus negative. We already
filter that in ExoPlayerImpl for the publicly accessible value. However, we
forward the unfiltered value to other components like the LoadControl, which
may be confusing.

Subject: [PATCH 123/807] Prevent negative renderer timestamps when seeking
 back.

We are currently queuing periods in a way such that the new start position
lines up with the end of the previous period (to ensure continuous playback).
However, if the start position of the new period is larger than the total of
all previously played period durations, we may end up with negative renderer
timestamps when seeking back to the beginning of this new period. Negative
timestamps should be avoided as most decoders have problems handling them
correctly.

This change forces a renderer reset if we detect such a seek to a negative
renderer time and also resets the renderer offset to 0 every time all
renderers are disabled, as this is the only time where we can savely change
the offset of an existing media period.

Also, if playback starts with an ad, we choose the content position as
renderer offset to prevent the whole issue from occurring for the seek-behind-
midroll case.

Issue:#5323

+# ExoPlayer cast receiver #
+
+An HTML/JavaScript app which runs within a Google cast device and can be loaded
+and controller by an Android app which uses the ExoPlayer cast extension
+(https://github.com/google/ExoPlayer/tree/release-v2/extensions/cast).
+
+# Build the app #
+
+You can build and deploy the app to your web server and register the url as your
+cast receiver app (see: https://developers.google.com/cast/docs/registration).
+
+Building the app compiles JavaScript and CSS files. Dead JavaScript code of the
+app itself and their dependencies (like ShakaPlayer) is removed and the
+remaining code is minimized.
+
+## Prerequisites ##
+
+1. Install the most recent bazel release (https://bazel.build/) which is at
+   least 0.22.0.
+
+From within the root of the exo_receiver_app project do the following steps:
+
+2. Clone shaka from GitHub into the directory external-js/shaka-player:
+```
+# git clone https://github.com/google/shaka-player.git \
+       external-js/shaka-player
+```
+
+## 1. Customize html page and css (optional) ##
+
+(Optional) Edit index.html. **Make sure you do not change the id of the video
+element**.
+(Optional) Customize main.css.
+
+## 2. Build javascript and css files ##
+```
+# bazel build ...
+```
+## 3. Assemble the receiver app ##
+```
+# WEB_DEPLOY_DIR=www
+# mkdir ${WEB_DEPLOY_DIR}
+# cp bazel-bin/exo_receiver_app.js  ${WEB_DEPLOY_DIR}
+# cp bazel-bin/exo_receiver_styles_bin.css ${WEB_DEPLOY_DIR}
+# cp html/index.html ${WEB_DEPLOY_DIR}
+```
+
+Deploy the content of ${WEB_DEPLOY_DIR} to your web server.
+
+## 4. Assemble the debug app (optional) ##
+
+Debugging the player in a cast device is a little bit cumbersome compared to
+debugging in a desktop browser. For this reason there is a debug app which
+contains the player parts which are not depending on the cast library in a
+traditional HTML app which can be run in a desktop browser.
+
+```
+# WEB_DEPLOY_DIR=www
+# mkdir ${WEB_DEPLOY_DIR}
+# cp bazel-bin/debug_app.js ${WEB_DEPLOY_DIR}
+# cp bazel-bin/debug_styles_bin.css ${WEB_DEPLOY_DIR}
+# cp html/player.html ${WEB_DEPLOY_DIR}
+```
+
+Deploy the content of ${WEB_DEPLOY_DIR} to your web server.
+
+# Unit test
+
+Unit tests can be run by the command
+```
+# bazel test ...
+```

 ConcatenatingMediaSource.

The total window and period count, as well as the period offset for each holder
are not actually needed and can be removed.

Also added a TODO to remove two other variables if possible.

-# ExoPlayer cast receiver #
-
-An HTML/JavaScript app which runs within a Google cast device and can be loaded
-and controller by an Android app which uses the ExoPlayer cast extension
-(https://github.com/google/ExoPlayer/tree/release-v2/extensions/cast).
-
-# Build the app #
-
-You can build and deploy the app to your web server and register the url as your
-cast receiver app (see: https://developers.google.com/cast/docs/registration).
-
-Building the app compiles JavaScript and CSS files. Dead JavaScript code of the
-app itself and their dependencies (like ShakaPlayer) is removed and the
-remaining code is minimized.
-
-## Prerequisites ##
-
-1. Install the most recent bazel release (https://bazel.build/) which is at
-   least 0.22.0.
-
-From within the root of the exo_receiver_app project do the following steps:
-
-2. Clone shaka from GitHub into the directory external-js/shaka-player:
-```
-# git clone https://github.com/google/shaka-player.git \
-       external-js/shaka-player
-```
-
-## 1. Customize html page and css (optional) ##
-
-(Optional) Edit index.html. **Make sure you do not change the id of the video
-element**.
-(Optional) Customize main.css.
-
-## 2. Build javascript and css files ##
-```
-# bazel build ...
-```
-## 3. Assemble the receiver app ##
-```
-# WEB_DEPLOY_DIR=www
-# mkdir ${WEB_DEPLOY_DIR}
-# cp bazel-bin/exo_receiver_app.js  ${WEB_DEPLOY_DIR}
-# cp bazel-bin/exo_receiver_styles_bin.css ${WEB_DEPLOY_DIR}
-# cp html/index.html ${WEB_DEPLOY_DIR}
-```
-
-Deploy the content of ${WEB_DEPLOY_DIR} to your web server.
-
-## 4. Assemble the debug app (optional) ##
-
-Debugging the player in a cast device is a little bit cumbersome compared to
-debugging in a desktop browser. For this reason there is a debug app which
-contains the player parts which are not depending on the cast library in a
-traditional HTML app which can be run in a desktop browser.
-
-```
-# WEB_DEPLOY_DIR=www
-# mkdir ${WEB_DEPLOY_DIR}
-# cp bazel-bin/debug_app.js ${WEB_DEPLOY_DIR}
-# cp bazel-bin/debug_styles_bin.css ${WEB_DEPLOY_DIR}
-# cp html/player.html ${WEB_DEPLOY_DIR}
-```
-
-Deploy the content of ${WEB_DEPLOY_DIR} to your web server.
-
-# Unit test
-
-Unit tests can be run by the command
-```
-# bazel test ...
-```

Subject: [PATCH 159/807] FLV extractor fixes

1. Only output video starting from a keyframe
2. When calculating the timestamp offset to adjust live streams to start
   at t=0, use the timestamp of the first tag from which a sample is actually
   output, rather than just the first audio/video tag. The test streams in
   the referenced GitHub issue start with a video tag whose packet type is
   AVC_PACKET_TYPE_SEQUENCE_HEADER (i.e. does not contain a sample) and whose
   timestamp is set to 0 (i.e. isn't set). The timestamp is set correctly on
   tags that from which a sample is actually output.

Issue: #6111

Subject: [PATCH 164/807] Move MediaSource masking code into separate class.

The masking logic for unprepared MediaSources is currently part of
ConcatanatingMediaSource. Moving it to its own class nicely separates the
code responsibilities and allows reuse.

Subject: [PATCH 168/807] Apply playback parameters in a consistent way.

Currently, we sometimes apply new playback parameters directly and sometimes
through the list of playbackParameterCheckpoints. Only when using the checkpoints,
we also reset the offset and corresponding position for speedup position
calculation. However, these offsets need to be changed in all cases to prevent
calculation errors during speedup calculation[1].

This change channels all playback parameters changes through the checkpoints to
ensure the offsets get updated accordingly. This fixes an issue introduced in
https://github.com/google/ExoPlayer/commit/31911ca54a13b0003d6cf902b95c2ed445afa930.

[1] - The speed up is calculated using the ratio of input and output bytes in
SonicAudioProcessor.scaleDurationForSpeedUp. Whenever we set new playback
parameters to the audio processor these two counts are reset. If we don't reset
the offsets too, the scaled timestamp can be a large value compared to the input
and output bytes causing massive inaccuracies (like the +20 seconds in the
linked issue).

Issue:#6117

Subject: [PATCH 171/807] Clean up DRM post requests

- Explicitly specify HTTP_METHOD_POST (previously this was
  implicit as a result of the body data being non-null)
- Use null when there's no body data (it's converted to
  null inside of the DataSpec constructor anyway)

Subject: [PATCH 175/807] CEA608: Fix repeated Special North American chars.

We currently handle most the control code logic after handling special
characters. This includes filtering out repeated control codes and checking
for the correct channel. As the special character sets are control codes as well,
these checks should happen before parsing the characters.

Issue:#6133

Subject: [PATCH 185/807] add manifest to Timeline.Window

- Remove manifest argument from callbacks of Player.EventListener and
  SourceInfoRefreshListener. Instead make it accessible through
  Player.getCurrentManifest() and Timeline.Window.manifest.
- Fix all MediaSource implementation to include the manifest in the
  Timeline instead of passing it to the SourceInfoRefreshListener.
- Refactor ExoPlayerTestRunner, FakeTimeline, FakeMediaSource to
  reflect these changes and make tests pass.

ExtractorMediaSource.addEventListener is currently a no-op because it's not
forwarded.

Subject: [PATCH 210/807] Keep default start position (TIME_UNSET) as content
 position for preroll ads.

If we use the default start position, we currently resolve it immediately
even if we need to play an ad first, and later try to project forward again
if we believe that the default start position should be used.

This causes problems if a specific start position is set and the later
projection after the preroll ad shouldn't take place.

The problem is solved by keeping the content position as TIME_UNSET (= default
position) if an ad needs to be played first. The content after the ad can
then be resolved to its current default position if needed.

Subject: [PATCH 213/807] Switch language normalization to 2-letter language
 codes.

2-letter codes (ISO 639-1) are the standard Android normalization and thus we
should prefer them to 3-letter codes (although both are technically allowed
according the BCP47).

This helps in two ways:
 1. It simplifies app interaction with our normalized language codes as the
    Locale class makes it easy to convert a 2-letter to a 3-letter code but
    not the other way round.
 2. It better normalizes codes on API<21 where we previously had issues with
    language+country codes (see tests).
 3. It allows us to normalize both ISO 639-2/T and ISO 639-2/B codes to the same
    language.

Subject: [PATCH 217/807] Further language normalization tweaks for API < 21.

1. Using the Locale on API<21 doesn't make any sense because it's a no-op
   anyway. Slightly restructured the code to avoid that.
2. API<21 often reports languages with non-standard underscores instead of
   dashes. Normalize that too.
3. Some invalid language tags on API>21 get normalized to "und". Use original
   tag in such a case.

Issue:#6153

Subject: [PATCH 218/807] Correctly mask playback info changes in
 ExoPlayerImpl.

PlaybackInfo changes are one of the last ones not masked and reported in the same
way as all other changes.

The main change to support this is to also mask the parameters set in
DefaultAudioSink.

Subject: [PATCH 226/807] Make one of the ExoPlayerTest tests more sensible.

Some variables were defined although they are the default and other things
were set-up in a non-sensible way, e.g. asserting that audio is selected
although no audio renderer is available, or using unset duration for
everything.

Subject: [PATCH 231/807] Simplify and improve text selection logic.

This changes the logic in the following ways:
 - If no preferred language is matched, prefer better scores for the selected
   audio language.
 - If a preferred language is matched, always prefer the better match
   irrespective of default or forced flags.
 - If a preferred language score and the isForced flag is the same, prefer
   tracks with a better selected audio language match.

Subject: [PATCH 233/807] Report mediaPeriodCreated/Released in
 MaskingMediaSource.

Creating a period in MaskingMediaSource may result in delayed event reporting
depending on when the actual period gets created. To avoid event reporting
inaccuracies, report the mediaPeriodCreated and mediaPeriodReleased events
directly.

Subject: [PATCH 234/807] Improve knowledge of last playing period in
 AnalyticsCollector.

We keep track of the last publicly known playing period to report it as part
of events happening after the period has been released.

In cases where a period briefly becomes the playing one and is released
immediately afterwards, we currently don't save it as the "last known playing
one". Improve that by saving an explicit reference.

Subject: [PATCH 238/807] Fix handling of channel count changes with speed
 adjustment

When using speed adjustment it was possible for playback to get stuck at a
period transition when the channel count changed: SonicAudioProcessor would be
drained at the point of the period transition in preparation for creating a new
AudioTrack with the new channel count, but during draining the incorrect (new)
channel count was used to calculate the output buffer size for pending data from
Sonic. This meant that, for example, if the channel count changed from stereo to
mono we could have an output buffer size that stored an non-integer number of
audio frames, and in turn this would cause writing to the AudioTrack to get
stuck as the AudioTrack would prevent writing a partial audio frame.

Use Sonic's current channel count when draining output to fix the issue.

Subject: [PATCH 242/807] Swap reading and playing media period updates.

Both periods are rarely updated in the same iteration. If they are, advancing
the reading period first seems more logical and also more efficient as it may
avoid one extra doSomeWork iteration.

Subject: [PATCH 245/807] Support different drm schemes in playlists in the
 demo app

This CL changes PlayerActivity's VIEW_LIST action intent contract:
Each media item configuration is provided by indexing the entries.
For example, the URI of the first item is passed as "uri_0", the
second one is "uri_1", etc. Optionally, the extra parameters, like
the extensions, are passed as "extension_1", where the intent extras
with matching indices, refer to the same media sample.

The VIEW action's contract remains unchanged.

Subject: [PATCH 246/807] Cast: Add MediaItemConverter

For now this just moves some code from the demo app to the extension.
Eventually the goal would be to have CastPlayer playlist methods take
MediaItem, have CastPlayer convert them internally to MediaQueueItem
for sending to the Cast SDK, and also allow reverse conversion so we
can reconstruct MediaItems from the Cast SDK's queue.

Subject: [PATCH 253/807] Improve DefaultMediaClock behaviour.

DefaultMediaClock has currently two non-ideal behaviours:
1. One part of checking if it should use the renderer clock is checking whether
   the associated renderer finished reading its stream. This only makes sense
   if the renderer isn't already reading ahead into the next period. This can
   be solved by forwarding if we are reading ahead to the sync command.
2. When switching from stand-alone to renderer clock we assume they are
   exactly at the same position. This is true in theory, but in practise there
   may be small differences due to the different natures of these clocks. To
   prevent jumping backwards in time, we can temporarily stop the stand-alone
   clock and only switch once the renderer clock reached the same position.

Subject: [PATCH 255/807] Add @NonNullApi and annotate two packages with it.

This new annotation declares everything as non-null by default and can be
used as a package annotation in package-info.java.

In this change the core lib offline package and the mediasession extension is
annotated that way as initial example usage.

Subject: [PATCH 261/807] Mp3Extractor: Avoid outputting non-zero position seek
 frame as a sample

Checking inputPosition == 0 isn't sufficient because the synchronization
at the top of read() may advance the input (i.e. in the case where there's
some garbage prior to the seek frame).

Subject: [PATCH 266/807] Standardize ALAC initialization data

Android considers ALAC initialization data to consider of the magic
cookie only, where-as FFmpeg requires a full atom. Standardize around
the Android definition, since it makes more sense (the magic cookie
being contained within an atom is container specific, where-as the
decoder shouldn't care what container the media stream is carried in)

Subject: [PATCH 270/807] Revert to using header bitrate for CBR MP3s

A previous change switched to calculation of the bitrate based on the
first MPEG audio header in the stream. This had the effect of fixing
seeking to be consistent with playing from the start for streams where
every frame has the same padding value, but broke streams where the
encoder (correctly) modifies the padding value to match the declared
bitrate in the header.

Issue: #6238

These values can easily default to the empty track group and the empty
selection. As a result we can remove restrictions about not calling

Subject: [PATCH 274/807] Fix AnalyticsCollectorTest flakiness.

Two tests have very low propability flakiness (1:1000) due to not waiting for
a seek in one case and the chance of already being ended in another case.

Fix these and also adjust wrong comments about state changes.

Subject: [PATCH 276/807] Fix DefaultOggSeeker seeking

- When in STATE_SEEK with targetGranule==0, seeking would exit
  without checking that the input was positioned at the correct
  place.
- Seeking could fail due to trying to read beyond the end of the
  stream.
- Seeking was not robust against IO errors during the skip phase
  that occurs after the binary search has sufficiently converged.

Subject: [PATCH 277/807] Improve extractor tests based on ExtractorAsserts

- Test seeking to (timeUs=0, position=0), which should always work
  and produce the same output as initially reading from the start
  of the stream.
- Reset the input when testing seeking, to ensure IO errors are
  simulated for this case.

Subject: [PATCH 283/807] Ensure position reset keep window sequence number.

We currently keep the sequence number if we don't reset the position. However,
the sequence number should be kept if we don't reset the state. Otherwise
re-prepare with position reset is counted as new playback although it's still
the same.

Subject: [PATCH 287/807] Update stale TrackSelections in chunk sources when
 keeping the streams.

If we keep streams in chunk sources after selecting new tracks, we also keep
a reference to a stale disabled TrackSelection object. Fix this by updating
the TrackSelection object when keeping the stream. The static part of the
selection (i.e. the subset of selected tracks) stays the same in all cases.

Issue:#6256

Subject: [PATCH 290/807] Add inband emsg-v1 support to FragmentedMp4Extractor

This also decouples EventMessageEncoder's serialization schema from the emesg spec (it happens to still match the emsg-v0 spec, but this is no longer required).

Subject: [PATCH 302/807] Simplify EventMessageEncoder/Decoder serialization

We're no longer tied to the emsg spec, so we can skip unused fields
and assume ms for duration.

Also remove @Nullable annotation from EventMessageEncoder#encode, it
seems the current implementation never returns null

Subject: [PATCH 307/807] Only read from FormatHolder when a format has been
 read

I think we need to start clearing the holder as part of the
DRM rework. When we do this, it'll only be valid to read
from the holder immediately after it's been populated.

Subject: [PATCH 308/807] Merge robolectric_testutils into testutils.

We no longer need two modules as AndroidX-Test takes care of the system
abstraction and we no longer have Robolectric Handler/Looper workarounds.

Subject: [PATCH 321/807] Change default video buffer size to 32MB.

The current max video buffer is 13MB which is too small for high quality
streams and doesn't allow the DefaultLoadControl to buffer up to its default
max buffer time of 50 seconds.

Also move util method and constants only used by DefaultLoadControl into this
class.

 `entries`

entries are used in .equals(), so it's good to have them printed in toString() too (for test failures) and it makes logging easier too.

Subject: [PATCH 324/807] Add builders for SimpleExoPlayer and ExoPlayer.

The current ExoPlayerFactory is growing too big and usage becomes increasingly
complicated because it's not possible to set individual components without
specifying many other defaults.

Adding new builder classes makes building easier and more future-proof.

Subject: [PATCH 328/807] Expand FakeSampleStream to allow specifying a single
 sample

I removed the buffer.flip() call because it seems incompatible with the way MetadataRenderer deals with the Stream - it calls flip() itself on line 126. Tests fail with flip() here, and pass without it...

Subject: [PATCH 338/807] Update window/period doc in Timeline.

Most users are likely to be only interested in the playlist items. So put the
Window definition first and explicitly mention that this is a playlist
item.

Subject: [PATCH 342/807] Advance playing period even if the next one isn't
 prepared yet.

This solves various issues around event association for buffering and
error throwing around period discontinuities.

The main changes are:
 - Logic around being "ready" at the end of a period no longer checks if the
   next period is prepared.
 - Advancing the playing period no longer checks if the next one is prepared.
 - Prepare errors are always thrown for the playing period.

This changes the semantics and assumptions about the "playing" period:
 1. The playing period can no longer assumed to be prepared.
 2. We no longer have a case where the queue is non-empty and the playing or
    reading periods are unassigned (=null).
Most other code changes ensure that these changed assumptions are handled.

Issue:#5407

Subject: [PATCH 343/807] Deprecate setTag parameter in Timeline.getWindow.

There is no point in having this parameter as the tag should always be a single
immutable object instantiated at the time the Timeline is created or earlier.

So there is no preformance benefit and it's error-prone in case people
forget to set setTag=true.

Subject: [PATCH 346/807] Fix handling of delayed AdsLoader.start

AdsMediaSource posts AdsLoader.start to the main thread during preparation, but
the app may call AdsLoader.setPlayer(null) before it actually runs (e.g., if
initializing then quickly backgrounding the player).

This is valid usage of the API so handle this case instead of asserting. Because
not calling setPlayer at all is a pitfall of the API, track whether setPlayer
has been called and still assert that in AdsLoader.start.

Subject: [PATCH 347/807] Support out-of-band HDR10+ metadata for VP9

Extract supplemental data from block additions in WebM/Matroska.

Allow storing supplemental data alongside samples in the SampleQueue and write
it as a separate field in DecoderInputBuffers.

Handle supplemental data in the VP9 extension by propagating it to the output
buffer.

Handle supplemental data for HDR10+ in MediaCodecVideoRenderer by passing it to
MediaCodec.setParameters, if supported by the component.

Subject: [PATCH 348/807] Gracefully handle chunkful preparation without
 chunks.

This situation happens if the first chunk to load is already behind the end
of the stream. In this case, the preparation never completes because
HlsSampleStreamWrapper gets stuck in a prepared=false and loadingFinished=true
state.

Gracefully handle this situation by attempting to load the last chunk if still
unprepared to ensure that track information is obtained as far as possible.
Otherwise, it wouldn't be possible to play anything even when seeking back.

Subject: [PATCH 350/807] Avoid potential ArrayStoreException with audio
 processors

The app is able to pass a more specialized array type, so the Arrays.copyOf call
produces an array into which it's not valid to store arbitrary AudioProcessors.

Create a new array and copy into it to avoid this problem.

Subject: [PATCH 351/807] Update comment to indicate correct int value of
 "FLAG_ALLOW_CACHE_FRAGMENTATION" in ExoPlayer2 upstream DataSpec

Currently the value of FLAG_ALLOW_CACHE_FRAGMENTATION is defined as "1 << 4" but commented as "8". Either the value of FLAG_ALLOW_CACHE_FRAGMENTATION should be "1 << 3", or the comment should be 16. Here I am modifying the comment since it does not affect any current behavior.

Subject: [PATCH 352/807] Move playback error into PlaybackInfo.

The error is closely related to the playback state IDLE and should be updated
in sync with the state to prevent unexpected event ordering and/or keeping the
error after re-preparation.

Issue:#5407

Subject: [PATCH 353/807] Add @CallSuper annotations in SimpleDecoder

The implementation can't work properly unless these methods are called by
subclasses, so annotate them to require calling the super implementation when
overriding.

Subject: [PATCH 355/807] Defer adsManager.init until the timeline has loaded

If the app seeks after we get an ads manager but before the player exposes the
timeline with ads, we would end up expecting to play a preroll even after the
seek request arrived. This caused the player to get stuck.

Wait until a non-empty timeline has been exposed via onTimelineChanged before
initializing IMA (at which point it can start polling the player position). Seek
requests are not handled while an ad is playing.

Subject: [PATCH 358/807] Add back deprecated getWindow to ForwardingTimeline.

Implementations of ForwardingTimeline may override any of the two variants of
this method. We need to ensure that the customized override is always called.

Add back the deprecated method and make it final to forward to the
non-deprecated method in all cases for ForwardingTimelines.

Subject: [PATCH 360/807] Avoid infinite recursion if cache file modified
 underneath cache

This generalizes our "does file still exist" check to also check
that the file is the expected length. If it's not, we don't trust
it. This avoids infinite recursion in CacheDataSource if a cache
file is truncated underneath the cache.

 ### dev-v2 (not yet released) ###
 
+* Surface information provided by methods `isHardwareAccelerated`,
+  `isSoftwareOnly` and `isVendor` added in Android Q in `MediaCodecInfo` class
+  ([#5839](https://github.com/google/ExoPlayer/issues/5839)).
 * Update `DefaultTrackSelector` to apply a viewport constraint for the default
   display by default.
 * Add `PlaybackStatsListener` to collect `PlaybackStats` for playbacks analysis

Subject: [PATCH 372/807] Move DefaultHttpDataSource request header explanation
 to class Javadoc.

The Javadoc for open() won't be read by anyone because it's an overridden method
of the interface and not called directly from application code.

Move doc to class documentation as this is a generic explanation about the
functionality of the class. Also added "all" to clarify that all the parameters
will be added and the order of preference just applies in case of key clashes.

Subject: [PATCH 387/807] Use DataSpec request params in HttpDataSource impls

Include Dataspec.httpRequestHeaders in CronetDataSource,
and OkHttpDataSource. Updated documentation of
HttpDataSource.open() to suggest that it should set request
headers (in decreasing priority) from (1) the passed DataSpec,
(2) parameters set with setRequestProperty() and (3) default
parameters set in the HttpDataSource.Factory. No mechanism
has been put in place to enforce this.

Subject: [PATCH 390/807] Prevent audio pops on audio format change. We'd like
 to switch opus audio bitrates in the middle of playback based on network
 conditions.

Changing between different bitrates on the same codec should not require decoder initialization.

Subject: [PATCH 391/807] Remove deprecated Timeline.getWindow method.

Removing this method requires custom MediaSource implementations to switch
to the new version. While this breaks the implmentation, it also avoids problems
with accidentely forwarding to the wrong method or with accidental stack
overflows when none of the two methods gets implemented.

It's unlikely any callers are affected because this is only the extended version
with the defaultProjectionPositionUs parameter that no caller except the
internal player will use.

Subject: [PATCH 396/807] Handle potential timeline updates that switch from
 content to ad.

We currently don't test if an ad needs to be played in case we are already
playing content.

This is to prevent recreating the current content period when
an ad is marked as skipped. We prefer playing until the designated ad group
position and appending another piece of content. This is less likely to cause
visible discontinuities in case the ad group position is at a key frame
boundary.

However, this means we currently miss updates that require us to play an ad
after a timeline update.

When the queue is empty, we may still get multiple requests for a window
sequence number using the same periodUid. We should keep the initially
assigned number because no window change happened.

We currently force render the first frame in all cases. However, when joining
video to an ongoing playback, there is no defined first frame and we should
rather drop frames if we are late until we caught up with the audio playback.

Subject: [PATCH 421/807] Add Player.isPlaying and
 Player.getPlaybackSuppressionReason

The player may suppress playback when waiting for audio focus even if the
state==Player.READY. There is currently no getter or callback to obtain this
piece of information for UI updates or analytics.

Also, it's a important derived state to know whether the playback position is
advancing. Add isPlaying and the corresponding callback to allow retrieving
this information more easily.

Subject: [PATCH 423/807] Fix playback speed in MediaSessionConnector

The playback speed set in MediaSession's PlaybackStateCompat needs to be the
actual speed at which the playback position progresses and not the user-defined
target speed.

This fixed a bug where the position advances although the player lost audio
focus.

Subject: [PATCH 425/807] Add DummyExoMediaDrm

Allows streamlining the way we handle unsupported DRM. In general, either:

* The device does not support the CDM. For example, phones don't support
  PlayReady.
* The device does not support the protection scheme. For example, API < 25
  devices do not support AES-CBC.

Currently we handle both cases differently. A dummy ExoMediaDrm will allow
the existence of dummy DefaultDrmSessionManagers.

+* Add `uid` to `Timeline.Window` to uniquely identify window instances.
+* Fix Dolby Vision fallback to AVC and HEVC.
+* Add `Player.isPlaying` and `EventListener.onIsPlayingChanged` to check whether
+  the playback position is advancing. This helps to determine if playback is
+  suppressed due to audio focus loss. Also add
+  `Player.getPlaybackSuppressedReason` to determine the reason of the
+  suppression ([#6203](https://github.com/google/ExoPlayer/issues/6203)).

+### 2.10.5 ###
+
+* Track selection
+  * Add `allowAudioMixedChannelCountAdaptiveness` parameter to
+    `DefaultTrackSelector` to allow adaptive selections of audio tracks with
+    different channel counts.
+  * Improve text selection logic to always prefer the better language matches
+    over other selection parameters.
+  * Fix audio selection issue where languages are compared by bitrate
+    ([#6335](https://github.com/google/ExoPlayer/issues/6335)).
+* Performance
+  * Increase maximum video buffer size from 13MB to 32MB. The previous default
+    was too small for high quality streams.
+  * Reset `DefaultBandwidthMeter` to initial values on network change.
+  * Bypass sniffing in `ProgressiveMediaPeriod` in case a single extractor is
+    provided ([#6325](https://github.com/google/ExoPlayer/issues/6325)).
+* Metadata
+  * Support EMSG V1 boxes in FMP4.
+  * Support unwrapping of nested metadata (e.g. ID3 and SCTE-35 in EMSG).
 * Add `HttpDataSource.getResponseCode` to provide the status code associated
   with the most recent HTTP response.
+* Fix initialization data handling for FLAC in MP4
+  ([#6396](https://github.com/google/ExoPlayer/issues/6396),
+  [#6397](https://github.com/google/ExoPlayer/issues/6397)).
+* Fix decoder selection for E-AC3 JOC streams
+  ([#6398](https://github.com/google/ExoPlayer/issues/6398)).
+* Fix `PlayerNotificationManager` to show play icon rather than pause icon when
+  playback is ended ([#6324](https://github.com/google/ExoPlayer/issues/6324)).
 * OkHttp extension: Upgrade OkHttp to fix HTTP2 socket timeout issue
   ([#4078](https://github.com/google/ExoPlayer/issues/4078)).
 * RTMP extension: Upgrade LibRtmp-Client-for-Android to fix RTMP playback issues

Subject: [PATCH 451/807] avoid unexpected state changes with certain playlist
 states

With the internal playlist some new situation may happen that were not possible before:

- handlePlaylistInfoRefreshed in EPII called in IDLE state
- handlePlaylistInfoRefreshed in EPII called in ENDED state with an empty playlist
- seeks in ENDED state with an empty playlist

+# ExoPlayer SurfaceControl demo
+
+This app demonstrates how to use the [SurfaceControl][] API to redirect video
+output from ExoPlayer between different views or off-screen. `SurfaceControl`
+is new in Android 10, so the app requires `minSdkVersion` 29.
+
+The app layout has a grid of `SurfaceViews`. Initially video is output to one
+of the views. Tap a `SurfaceView` to move video output to it. You can also tap
+the buttons at the top of the activity to move video output off-screen, to a
+full-screen `SurfaceView` or to a new activity.
+
+When using `SurfaceControl`, the `MediaCodec` always has the same surface
+attached to it, which can be freely 'reparented' to any `SurfaceView` (or
+off-screen) without any interruptions to playback. This works better than
+calling `MediaCodec.setOutputSurface` to change the output surface of the codec
+because `MediaCodec` does not re-render its last frame when that method is
+called, and because you can move output off-screen easily (`setOutputSurface`
+can't take a `null` surface, so the player has to use a `DummySurface`, which
+doesn't handle protected output on all devices).

Subject: [PATCH 456/807] Issue: #6501 Wrong segmentNumShift was calculated in
 copyWithNewRepresentation

In DefaultDashChunkSource.copyWithNewRepresentation, it will handle the logic that
new MPD manifest file is updated and calculate a newSegmentNumShift for furthermore
segNum index calculation in getSegmentUrl, when a shorter window MPD updated and then
back to a longer window MPD, copyWithNewRepresentation will go into the overlap case
but the new index actually contains the old index..

Inline invocations of these methods, which still leaks the MediaDrms.
However, it will be fixed once the DefaultDrmSessionManager API is finalized
and ExoMediaDrm.Providers are introduced.

Subject: [PATCH 464/807] Use Player.isPlaying in appropriate places.

This method should be used where we previously checked for active playback
by state==READY and playWhenReady=true. Using the new method ensures we take
audio focus into account for these usages.

Also update some method naming to avoid confusion with the isPlaying method.

Subject: [PATCH 465/807] Remove mediaDrm methods from DefaultDrmSessionManager

DrmSessionManagers may now be in released state, in which case they
may release their MediaDrm. In that case, it would be invalid to
forward method calls to the underlying MediaDrms. Users should
instead call these methods directly on the MediaDrm.

Subject: [PATCH 469/807] Add EventListener.onPlaybackSuppressionReasonChanged

Adding this callback makes sense for completeness (we have similar callbacks
for all other playback state properties), and also to detect audio focus loss
while buffering which would currently trigger no callback because isPlaying
is still false.

Subject: [PATCH 485/807] Add Timeline.Window.isLive

This flag is currently merged into Window.isDynamic, which isn't always true
because
1. A window can be dynamic for other reasons (e.g. when the duration is still
missing).
2. A live stream can be become non-dynamic when it ends.

 https://github.com/google/ExoPlayer/commit/01f484cbe965f7858f9621c97fec94d30eef188a

*** Original commit ***

Modify EventMessageDecoder to return null if decoding fails (currently throws exceptions)

This matches the documentation on MetadataDecoder.decode:
"@return The decoded metadata object, or null if the metadata could not be decoded."

Subject: [PATCH 494/807] Clear renderedFirstFrame at stream changes even if no
 reconfiguration is needed

This ensures a more consistent playback behavior no matter if an item is the
first playlist item or a later one. For example, each playlist item gets its
own onRenderedFirstFrame callback and other logic within the renderer that
force renders the first frame more quickly is also triggered.

Subject: [PATCH 509/807] Update logic to set isLoading.

We currently set it to shouldContinueLoading, which isn't correct if
shouldContinueLoading is set to false and we still have an ongoing load.

Change it to also be true if the media period is still loading.

Subject: [PATCH 512/807] Cleanup: Only clamp seek positions for FFWD/RWND

It's confusing that seekTo(player, windowIndex, positionMs) does
clamping, because it only makes sense if windowIndex is the current
window.

Note: This doesn't actually fix anything (other than code clarity).
In cases where we were passing other windowIndices, we always
passed 0 as the position and so the clamping logic wouldn't have
had any effect.

 Libgav1VideoRenderer

Move reusable code from LibvpxVideoRenderer to SimpleDecoderVideoRenderer.
Pass outputBuffer to renderOutputBuffer method instead of keeping the reference in the renderer.

that derive from it, but the corresponding setter does not. It
seems generally clearer just to define constants.

Subject: [PATCH 526/807] Delete the IMA demo

This doesn't offer anything on top of the functionality in the main demo app.
There's less code but we have a blog post and presentations that walk through
how to use the extension, so it seems fine to delete the code so we don't need
to maintain it. This also avoids potential confusion about what the demo app
means on IMA-related GitHub issues.

+# ExoPlayer AV1 extension #
+
+The AV1 extension provides `Libgav1VideoRenderer`, which uses libgav1 native
+library to decode AV1 videos.
+
+## License note ##
+
+Please note that whilst the code in this repository is licensed under
+[Apache 2.0][], using this extension also requires building and including one or
+more external libraries as described below. These are licensed separately.
+
+[Apache 2.0]: https://github.com/google/ExoPlayer/blob/release-v2/LICENSE
+
+## Build instructions ##
+
+To use this extension you need to clone the ExoPlayer repository and depend on
+its modules locally. Instructions for doing this can be found in ExoPlayer's
+[top level README][].
+
+In addition, it's necessary to fetch libgav1 and its dependencies as follows:
+
+* Set the following environment variables:
+
+```
+cd "<path to exoplayer checkout>"
+EXOPLAYER_ROOT="$(pwd)"
+AV1_EXT_PATH="${EXOPLAYER_ROOT}/extensions/av1/src/main"
+```
+
+* Fetch libgav1:
+
+```
+cd "${AV1_EXT_PATH}/jni" && \
+git clone https://chromium.googlesource.com/codecs/libgav1 libgav1
+```
+
+* Fetch Abseil:
+
+```
+cd "${AV1_EXT_PATH}/jni/libgav1" && \
+git clone https://github.com/abseil/abseil-cpp.git third_party/abseil-cpp
+```
+
+libgav1 and [JNI wrapper library][] are built using [CMake][] set-up with
+[Ninja][]. After following the instructions above to fetch libgav1, gradle will
+build the extension automatically when run on the command line or via Android
+Studio.
+
+[top level README]: https://github.com/google/ExoPlayer/blob/release-v2/README.md
+[JNI wrapper library]: https://github.com/google/ExoPlayer/blob/release-v2/extensions/av1/src/main/jni/gav1_jni.cc
+[CMake]: https://cmake.org/
+[Ninja]: https://ninja-build.org
+
+## Using the extension ##
+
+Once you've followed the instructions above to check out, build and depend on
+the extension, the next step is to tell ExoPlayer to use `Libgav1VideoRenderer`.
+How you do this depends on which player API you're using:
+
+* If you're passing a `DefaultRenderersFactory` to `SimpleExoPlayer.Builder`,
+  you can enable using the extension by setting the `extensionRendererMode`
+  parameter of the `DefaultRenderersFactory` constructor to
+  `EXTENSION_RENDERER_MODE_ON`. This will use `Libgav1VideoRenderer` for
+  playback if `MediaCodecVideoRenderer` doesn't support decoding the input AV1
+  stream. Pass `EXTENSION_RENDERER_MODE_PREFER` to give `Libgav1VideoRenderer`
+  priority over `MediaCodecVideoRenderer`.
+* If you've subclassed `DefaultRenderersFactory`, add a `Libvgav1VideoRenderer`
+  to the output list in `buildVideoRenderers`. ExoPlayer will use the first
+  `Renderer` in the list that supports the input media format.
+* If you've implemented your own `RenderersFactory`, return a
+  `Libgav1VideoRenderer` instance from `createRenderers`. ExoPlayer will use the
+  first `Renderer` in the returned array that supports the input media format.
+* If you're using `ExoPlayer.Builder`, pass a `Libgav1VideoRenderer` in the
+  array of `Renderer`s. ExoPlayer will use the first `Renderer` in the list that
+  supports the input media format.
+
+Note: These instructions assume you're using `DefaultTrackSelector`. If you have
+a custom track selector the choice of `Renderer` is up to your implementation.
+You need to make sure you are passing a `Libgav1VideoRenderer` to the player and
+then you need to implement your own logic to use the renderer for a given track.
+
+There are two possibilities for rendering the output `Libgav1VideoRenderer`
+gets from the libgav1 decoder:
+
+* Native rendering with `ANativeWindow`
+* OpenGL rendering.
+
+`SimpleExoPlayer` uses `ANativeWindow` rendering. To enable this mode send the
+renderer a message of type `C.MSG_SET_SURFACE` with a `Surface` as its object.
+`Libgav1VideoRenderer` can also output to a `VideoDecoderSurfaceView` when
+not being used via `SimpleExoPlayer`, in which case color space conversion will
+be performed using a GL shader. To enable this mode, send the renderer a message
+of type `C.MSG_SET_OUTPUT_BUFFER_RENDERER` with the `VideoDecoderSurfaceView` as
+its object.
+
+Note: Although the default option uses `ANativeWindow`, based on our testing the
+GL rendering mode has better performance, so should be preferred by apps that
+can use `VideoDecoderSurfaceView`.

 There are two possibilities for rendering the output `Libgav1VideoRenderer`
 gets from the libgav1 decoder:
 
-* Native rendering with `ANativeWindow`
-* OpenGL rendering.
+* GL rendering using GL shader for color space conversion
+  * If you are using `SimpleExoPlayer` with `PlayerView`, enable this option by

+    of type `C.MSG_SET_OUTPUT_BUFFER_RENDERER` with an instance of
+    `VideoDecoderOutputBufferRenderer` as its object.
 
-`SimpleExoPlayer` uses `ANativeWindow` rendering. To enable this mode send the

 Note: Although the default option uses `ANativeWindow`, based on our testing the
-GL rendering mode has better performance, so should be preferred by apps that

Subject: [PATCH 535/807] Fail av1 extension build if CMake is missing

If a user has checked out libgav1 they almost certainly want to
build the extension, so fail if CMake is not present but
libgav1 is present. Also add a note to the README linking to
instructions for installing CMake.

Also remove the NDK check, as ndk.dir is apparently deprecated
and Android Studio appears to install this automatically anyway.

Subject: [PATCH 547/807] Test audio focus denial

- Verifies that playWhenReady doesn't become true if audio focus
  is denied.
- Also verifies there's no suppression reason in this case, because
  the denial is permanent rather than temporary.

Subject: [PATCH 552/807] Make FileDataSourceFactory an inner class

This is a proof of concept for cleanup we should do for all of
our DataSource implementations as we move toward stabilizing
parts of the API.

- Move all XDataSourceFactory classes to be inner classes.
- Remove chained constructors for XDataSourceFactory classes. Keep
  required args going through constructors. Use setters for the
  rest.
- Not applicable in this case, but we probably want to deprecate
  all but the no-arg method for instantiating eac XDataSource
  instance (with the all-arg method kept but with the intention
  of making it package private).

Subject: [PATCH 554/807] Add a javadoc explanation for ProgressiveDownloader
 that explains that it tries to skip downloading already cached bytes.

download calls through to CacheUtil#cache, which handles skipping already downloaded bytes.

It is useful for callers to know that ProgressiveDownloader has this behavior - otherwise, they might reimplement the logic themselves.

I hope this behavior is something that can be part of the public API :)

If a surface was previously passed to the player then an output buffer
renderer was set, we would remove surface callbacks but not clear the
surface on renderers that accept MSG_SET_SURFACE.

single-element array.

- Simplify the supported formats configuration by moving it to a
  separate variable, therefore avoiding updating the COMMON_OPTIONS
  variable in the ffmpeg build command.
- Move the ffmpeg build command to a shell script.

Subject: [PATCH 571/807] Break the inheritance of
 FullSegmentEncryptionKeyCache

Use composition instead.

This makes the null-handling more explicit & complete (previous implementation
tried to prevent null values, but didn't override all mutation methods
e.g. replace(), putIfAbsent() etc.)

Subject: [PATCH 583/807] Round impossible H264 resolutions up to valid values
 for capabilities check

If an odd resolution is impossible in the specification itself, then we know
that the caller is passing invalid data. Round up on the assumption it's a
rounding error so that playback can proceed.

Subject: [PATCH 587/807] Refactor GlViewGroup to ViewRenderer

GlViewGroup doesn't work properly as an actual ViewGroup. For example,
it doesn't support addition of child views after instantiation. This
change turns the class into a renderer, which is also more consistent
with other classes in the package.

Subject: [PATCH 590/807] Replace @MonotonicNonNull with @Nullable for final
 variables.

@MonotonicNonNull is not useful if the variable is final, because it's only
assigned once and guaranteed to keep it's current nullability in the same
way as @MonotonicNonNull ensures it's kept non-null after checking.

This way, the workarounds can also be removed.

 HlsSampleStreamWrapper

This reverts https://github.com/google/ExoPlayer/commit/a81dea6a47c7df83f029e03080dd6878ab75f133 and adds in the necessary nullness annotations

After a discussion that this:: method references allocate on every call:

Subject: [PATCH 601/807] Remove VR code

- Leaving GvrAudioProcessor for now.
- Removing GvrPlayerActivity because it was never released. Also removing
  related UI classes. These were released, but it's unlikely anyone would
  have been using them directly.

 # ExoPlayer GVR extension #
 
+**DEPRECATED - If you still need this extension, please contact us by filing an
+issue on our [issue tracker][].**
+
 The GVR extension wraps the [Google VR SDK for Android][]. It provides a
 GvrAudioProcessor, which uses [GvrAudioSurround][] to provide binaural rendering
 of surround sound and ambisonic soundfields.
 
 [Google VR SDK for Android]: https://developers.google.com/vr/android/
 [GvrAudioSurround]: https://developers.google.com/vr/android/reference/com/google/vr/sdk/audio/GvrAudioSurround

Subject: [PATCH 608/807] Update parseStbl to handle edit lists & gapless info

Without this, a subtitle track empty edit list used to offset the start of
subtitles is ignored.

Also the current code seems to depend on the order in which
we parse the tracks (audio first means we have gapless info when we parse
video track, while video first we wouldn't).

It's not clear why we can't handle both edit lists & gapless info

Subject: [PATCH 611/807] Add assertWithMessage calls to WebvttDecoderTest

With lots of int comparisons close together, this makes the error
messages much clearer and saves having to manually match up line
numbers.

Also make every @Test just throw Exception

Subject: [PATCH 613/807] Use Float.NaN for Cue#DIMEN_UNSET

Float.MIN_VALUE is very close to zero:
"A constant holding the smallest positive nonzero value of type float"
https://developer.android.com/reference/java/lang/Float.html#MIN_VALUE

Float.NaN more clearly conveys this is an invalid number,
and will also more clearly carry over if we do maths on it accidentally.

Subject: [PATCH 621/807] Set internal state before setting up cast
 dependencies

Prevents access of fields before initialization. Also set
remoteMediaClient in the constructor by using setRemoteMediaClient
instead of assigning the field directly, which will (if possible)
pull the state of the receiver in the constructor.

Rollback of https://github.com/google/ExoPlayer/commit/bf01ff0f60930427cb8a31e88fcad009d89132cc

Float.NaN more clearly conveys this is an invalid number,
and will also more clearly carry over if we do maths on it a...

Subject: [PATCH 630/807] Fix incorrect anamorphic handling in Leanback
 extension

The leanback library doesn't know about non-square pixels. So if
we're playing content that uses non-square pixels, we need to adjust
the video dimensions that we provide to leanback such that it
renders the video with the correct aspect ratio.

Subject: [PATCH 640/807] Recreate Opus decoder for stream change

The framework opus decoder discards some samples after a call to
flush(). Because we flush a decoder that is being retained across an
input format change, this means that the start of audio gets truncated
when transitioning to a new opus stream. See also
https://android.googlesource.com/platform/frameworks/av/+/refs/heads/android10-release/media/libstagefright/codecs/opus/dec/SoftOpus.cpp.

Avoid this by recreating opus decoders instead of flushing them. It
seems fine to do this for all opus decoders as reinitialization should
be cheap, OEM-provided implementations may also discard samples and
playback shouldn't be interrupted on reinitialization due to the
downstream AudioTrack buffer.

Subject: [PATCH 645/807] Update WebvttCue to use defaults from the spec

Cue's UNSET and null values should be used when the source data
doesn't specify *and* the spec doesn't provide a clear default.
In the WebVTT case, the defaults are clear, so we use them
explicitly.

Subject: [PATCH 646/807] Switch (Mp4)WebvttDecoderTest to use Truth's Expect

This means multiple failures are all logged, instead of the test
stopping when the first assertion fails. Makes tests like this with
lots of independent assertions much easier to work with.

I limited the expect to a single assertCues() call, otherwise
the error message gets very long and is hard to read, but I
still think this is an improvement.

Subject: [PATCH 671/807] Update audio extension build configurations

- Fix FLAC extension build (currently broken due to use of std::array,
  but fixed by migrating to NDK r20).
- Move opus and ffmpeg extensions to NDK r20. For ffmpeg, upgrade to
  release 4.2 which requires using libswresample and updates to the
  build script.

Issue: #6601

Subject: [PATCH 672/807] Reset MediaSession shuffle/repeat modes if player is
 null

- This is for consistency with PlayerControlView.

- Also update PlayerNotificationManager notification if shuffle
  mode changes. This is for consistency with what happens when
  the repeat mode changes. By default the notification will be
  unchanged, but custom implementations can extend and then
  override createNotification, and given these modes change
  infrequently it feels like we can just do this. The alternative
  for achieving consistency would be to remove handling of repeat
  mode changes.

Subject: [PATCH 700/807] Fix extractor sniffing in FLAC extension

Assuming that a flac stream starts with bytes
['f', 'L', 'a', 'C', 0, 0, 0, 0x22] is not always correct as it could
also start with ['f', 'L', 'a', 'C', 0x80, 0, 0, 0x22]
(see https://xiph.org/flac/format.html#metadata_block_streaminfo).

Subject: [PATCH 707/807] Add test for becoming noisy handling

To trigger receiving the broadcast it's necessary to idle() the shadow
main looper, which has to be done from the test thread. Therefore this
change removes the send broadcast action and instead sends the broadcast
from the test thread.

Subject: [PATCH 716/807] Clarify SSA and SubRip docs in MatroskaExtractor

The handling of times wasn't really clear to me, hopefully this more
exhaustive documentation helps a bit.

Also assert the end timecode is the 'correct' length for the format.

Subject: [PATCH 717/807] Require an end timecode in SSA and Subrip subtitles

SSA spec allows the lines in any order, so they must all have an end time:
http://moodub.free.fr/video/ass-specs.doc

The Matroska write-up of SubRip assumes the end time is present:
https://matroska.org/technical/specs/subtitles/srt.html

This will massively simplify merging issue:#6595

 ### dev-v2 (not yet released) ###
 
+* Require an end time or duration for SubRip (SRT) and SubStation Alpha
+  (SSA/ASS) subtitles. This applies to both sidecar files & subtitles
+  [embedded in Matroska streams](https://matroska.org/technical/specs/subtitles/index.html).
+
 ### 2.11.0 (not yet released) ###
 
-* AV1 extension: Uses libgav1 to decode AV1 videos. Android 10 includes an AV1
-  decoder, but the older versions of Android require this extension for playback
-  of AV1 streams ([#3353](https://github.com/google/ExoPlayer/issues/3353)). You
-  can read more about playing AV1 videos with ExoPlayer
-  [here](https://medium.com/google-exoplayer/playing-av1-videos-with-exoplayer-a7cb19bedef9).
+* Core library:
+  * Replace `ExoPlayerFactory` by `SimpleExoPlayer.Builder` and
+    `ExoPlayer.Builder`.
+  * Add automatic `WakeLock` handling to `SimpleExoPlayer`, which can be enabled
+    by calling `SimpleExoPlayer.setHandleWakeLock`
+    ([#5846](https://github.com/google/ExoPlayer/issues/5846)). To use this
+    feature, you must add the
+    [WAKE_LOCK](https://developer.android.com/reference/android/Manifest.permission.html#WAKE_LOCK)
+    permission to your application's manifest file.
+  * Add automatic "audio becoming noisy" handling to `SimpleExoPlayer`, which
+    can be enabled by calling `SimpleExoPlayer.setHandleAudioBecomingNoisy`.
+  * Wrap decoder exceptions in a new `DecoderException` class and report them as
+    renderer errors.
+  * Add `Timeline.Window.isLive` to indicate that a window is a live stream
+    ([#2668](https://github.com/google/ExoPlayer/issues/2668) and
+    [#5973](https://github.com/google/ExoPlayer/issues/5973)).
+  * Add `Timeline.Window.uid` to uniquely identify window instances.
+  * Deprecate `setTag` parameter of `Timeline.getWindow`. Tags will always be
+    set.
+  * Deprecate passing the manifest directly to
+    `Player.EventListener.onTimelineChanged`. It can be accessed through
+    `Timeline.Window.manifest` or `Player.getCurrentManifest()`
+  * Add `MediaSource.enable` and `MediaSource.disable` to improve resource
+    management in playlists.
+  * Add `MediaPeriod.isLoading` to improve `Player.isLoading` state.
+  * Fix issue where player errors are thrown too early at playlist transitions
+    ([#5407](https://github.com/google/ExoPlayer/issues/5407)).
 * DRM:
   * Inject `DrmSessionManager` into the `MediaSources` instead of `Renderers`
     ([#5619](https://github.com/google/ExoPlayer/issues/5619)).
   * Add a `DefaultDrmSessionManager.Builder`.
   * Add support for the use of secure decoders in clear sections of content
     ([#4867](https://github.com/google/ExoPlayer/issues/4867)).
-  * Add basic DRM support to the Cast demo app.
   * Add support for custom `LoadErrorHandlingPolicies` in key and provisioning
     requests ([#6334](https://github.com/google/ExoPlayer/issues/6334)).
   * Remove `DefaultDrmSessionManager` factory methods that leak `ExoMediaDrm`
     instances ([#4721](https://github.com/google/ExoPlayer/issues/4721)).
-* Remove the `DataSpec.FLAG_ALLOW_ICY_METADATA` flag. Instead, set the header
-  `IcyHeaders.REQUEST_HEADER_ENABLE_METADATA_NAME` in the `DataSpec`
-  `httpRequestHeaders`.
+* Track selection:
+  * Update `DefaultTrackSelector` to set a viewport constraint for the default
+    display by default.
+  * Update `DefaultTrackSelector` to set text language and role flag
+    constraints for the device's accessibility settings by default
+    ([#5749](https://github.com/google/ExoPlayer/issues/5749)).
+  * Add option to set preferred text role flags using
+    `DefaultTrackSelector.ParametersBuilder.setPreferredTextRoleFlags`.
+* Android 10:
+  * Set `compileSdkVersion` to 29 to enable use of Android 10 APIs.
+  * Expose new `isHardwareAccelerated`, `isSoftwareOnly` and `isVendor` flags
+    in `MediaCodecInfo`
+    ([#5839](https://github.com/google/ExoPlayer/issues/5839)).
+  * Add `allowedCapturePolicy` field to `AudioAttributes` to allow to
+    configuration of the audio capture policy.
+* Video:
+  * Pass the codec output `MediaFormat` to `VideoFrameMetadataListener`.
+  * Support out-of-band HDR10+ metadata for VP9 in WebM/Matroska.
+  * Assume that protected content requires a secure decoder when evaluating
+    whether `MediaCodecVideoRenderer` supports a given video format
+    ([#5568](https://github.com/google/ExoPlayer/issues/5568)).
+  * Fix Dolby Vision fallback to AVC and HEVC.
+* Audio:
+  * Fix E-AC3 JOC passthrough playback failing to initialize due to incorrect
+    channel count check.
+  * Handle new signaling for E-AC3 JOC audio in DASH
+    ([#6636](https://github.com/google/ExoPlayer/issues/6636)).
+  * Fix the start of audio getting truncated when transitioning to a new
+    item in a playlist of Opus streams.
+  * Workaround broken raw audio decoding on Oppo R9
+    ([#5782](https://github.com/google/ExoPlayer/issues/5782)).
+* UI:
+  * Make showing and hiding player controls accessible to TalkBack in
+    `PlayerView`.
+  * Rename `spherical_view` surface type to `spherical_gl_surface_view`.
+* Analytics:
+  * Remove `AnalyticsCollector.Factory`. Instances should be created directly,
+    and the `Player` should be set by calling `AnalyticsCollector.setPlayer`.
+  * Add `PlaybackStatsListener` to collect `PlaybackStats` for analysis and
+    analytics reporting (TODO: link to developer guide page/blog post).
+* DataSource
+  * Add `DataSpec.httpRequestHeaders` to support setting per-request headers for
+    HTTP and HTTPS.
+  * Remove the `DataSpec.FLAG_ALLOW_ICY_METADATA` flag. Use is replaced by
+    setting the `IcyHeaders.REQUEST_HEADER_ENABLE_METADATA_NAME` header in
+    `DataSpec.httpRequestHeaders`.
+  * Fail more explicitly when local file URIs contain invalid parts (e.g. a
+    fragment) ([#6470](https://github.com/google/ExoPlayer/issues/6470)).
 * DASH: Support negative @r values in segment timelines
   ([#1787](https://github.com/google/ExoPlayer/issues/1787)).
-* Add `allowedCapturePolicy` field to `AudioAttributes` wrapper to allow to
-  opt-out of audio recording.
-* Add `DataSpec.httpRequestHeaders` to set HTTP request headers when connecting
-  to an HTTP source. `DefaultHttpDataSource`, `CronetDataSource` and
-  `OkHttpDataSource` include headers set in the DataSpec when connecting to the
-  source.
-* Surface information provided by methods `isHardwareAccelerated`,
-  `isSoftwareOnly` and `isVendor` added in Android 10 in `MediaCodecInfo` class
-  ([#5839](https://github.com/google/ExoPlayer/issues/5839)).
-* Update `DefaultTrackSelector` to apply a viewport constraint for the default
-  display by default.
-* Add `PlaybackStatsListener` to collect `PlaybackStats` for playbacks analysis
-  and analytics reporting (TODO: link to developer guide page/blog post).
-* Assume that encrypted content requires secure decoders in renderer support
-  checks ([#5568](https://github.com/google/ExoPlayer/issues/5568)).
-* Decoders: Prefer decoders that advertise format support over ones that do not,
-  even if they are listed lower in the `MediaCodecList`.
-* Add a workaround for broken raw audio decoding on Oppo R9
-  ([#5782](https://github.com/google/ExoPlayer/issues/5782)).
-* Wrap decoder exceptions in a new `DecoderException` class and report as
-  renderer error.
-* Do not pass the manifest to callbacks of `Player.EventListener` and
-  `SourceInfoRefreshListener` anymore. Instead make it accessible through
-  `Player.getCurrentManifest()` and `Timeline.Window.manifest`. Also rename
-  `SourceInfoRefreshListener` to `MediaSourceCaller`.
-* Set `compileSdkVersion` to 29 to use Android 10 APIs.
-* Add `enable` and `disable` methods to `MediaSource` to improve resource
-  management in playlists.
-* Text selection logic:
-  * Allow to set preferred role flags using
-    `DefaultTrackSelector.ParametersBuilder.setPreferredTextRoleFlags`.
-  * Default text language and role flags to accessibility captioning settings
-    ([#5749](https://github.com/google/ExoPlayer/issues/5749)).
-* Remove `AnalyticsCollector.Factory`. Instances can be created directly and
-  the `Player` set later using `AnalyticsCollector.setPlayer`.
-* Replace `ExoPlayerFactory` by `SimpleExoPlayer.Builder` and
-  `ExoPlayer.Builder`.
-* Fix issue where player errors are thrown too early at playlist transitions
-  ([#5407](https://github.com/google/ExoPlayer/issues/5407)).
-* Deprecate `setTag` parameter of `Timeline.getWindow`. Tags will always be set.
-* Support out-of-band HDR10+ metadata for VP9 in WebM/Matroska.
-* Fix issue where HLS streams get stuck in infinite buffering state after
-  postroll ad ([#6314](https://github.com/google/ExoPlayer/issues/6314)).
-* Publish `testutils` module to simplify unit testing with ExoPlayer
-  ([#6267](https://github.com/google/ExoPlayer/issues/6267)).
-* Add `uid` to `Timeline.Window` to uniquely identify window instances.
-* Fix Dolby Vision fallback to AVC and HEVC.
-* Add demo app to show how to use the Android 10 `SurfaceControl` API with
-  ExoPlayer ([#677](https://github.com/google/ExoPlayer/issues/677)).
-* Add automatic `WakeLock` handling to `SimpleExoPlayer` through calling
-  `setEnableWakeLock`, which requires the
-  `android.Manifest.permission#WAKE_LOCK` permission
-  ([#5846](https://github.com/google/ExoPlayer/issues/5846)).
+* HLS: Fix issue where streams could get stuck in an infinite buffering state
+  after a postroll ad
+  ([#6314](https://github.com/google/ExoPlayer/issues/6314)).
+* AV1 extension:
+  * New in this release. The AV1 extension allows use of the
+    [libgav1 software decoder](https://chromium.googlesource.com/codecs/libgav1/)
+    in ExoPlayer. You can read more about playing AV1 videos with ExoPlayer
+    [here](https://medium.com/google-exoplayer/playing-av1-videos-with-exoplayer-a7cb19bedef9).
 * VP9 extension:
-  * Rename `VpxVideoSurfaceView` to `VideoDecoderSurfaceView`
-    and move it to the core library.
+  * Update to use NDK r20.
+  * Rename `VpxVideoSurfaceView` to `VideoDecoderSurfaceView` and move it to the
+    core library.
   * Move `LibvpxVideoRenderer.MSG_SET_OUTPUT_BUFFER_RENDERER` to
     `C.MSG_SET_OUTPUT_BUFFER_RENDERER`.
   * Use `VideoDecoderRenderer` as an implementation of
     `VideoDecoderOutputBufferRenderer`, instead of `VideoDecoderSurfaceView`.
-* Rename `spherical_view` surface type to `spherical_gl_surface_view`.
-* Add automatic audio becoming noisy handling to `SimpleExoPlayer`,
-  available through `SimpleExoPlayer.setHandleAudioBecomingNoisy`.
-* Post `AudioFocusManager.onAudioFocusChange` events to eventHandler, avoiding
-  multithreaded access to the player or audio focus manager.
-* Add `Timeline.Window.isLive` to indicate that a window is a live stream
-  ([#2668](https://github.com/google/ExoPlayer/issues/2668) and
-  [#5973](https://github.com/google/ExoPlayer/issues/5973)).
-* Fail more explicitly when local-file Uris contain invalid parts (e.g.
-  fragment) ([#6470](https://github.com/google/ExoPlayer/issues/6470)).
-* Add `MediaPeriod.isLoading` to improve `Player.isLoading` state.
-* Make show and hide player controls accessible for TalkBack in `PlayerView`.
-* Pass the codec output `MediaFormat` to `VideoFrameMetadataListener`.
-* Deprecate the GVR extension.
-* Fix the start of audio getting truncated when transitioning to a new
-  item in a playlist of opus streams.
-* Fix FLAC extension build
-  ([#6601](https://github.com/google/ExoPlayer/issues/6601).
-* Update the ffmpeg, flac and opus extension build instructions to use NDK r20.
-* Update the ffmpeg extension to release 4.2. It is necessary to rebuild the
-  native part of the extension after this change, following the instructions in
-  the extension's readme.

Subject: [PATCH 723/807] Make DrmSession acquire/release consistent with
 ExoMediaDrm

This aligns the method naming and Javadoc. The only remaining
inconsistency I can see is that the initial reference count for
DrmSession is 0 rather than 1. Unfortunately I think it's not
trivial to get these aligned, because DefaultDrmSessionManager
relies on being able to do something between instantiation and
the DrmSession starting to open the session. In practice this
doesn't really matter, since DrmSessions will be obtained via the
manager, which does increment thee reference count to 1 to be
consistent with how ExoMediaDrm acquisition works.

Subject: [PATCH 725/807] Support switching between Surface and
 VideoDecoderOutputBufferRenderer

Clear state for one mode when entering the other in both SimpleExoPlayer
and SimpleDecoderVideoRenderer. The latter is redundant for the case of
renderers that are used inside SimpleExoPlayer, but seems nice to have.

- Entering Surface mode means receiving a non-null Surface, SurfaceHolder
  or TextureView in SimpleExoPlayer, or a non-null Surface in
  SimpleDecoderVideoRenderer.
- Entering VideoDecoderOutputBufferRenderer means receiving a non-null
  VideoDecoderOutputBufferRenderer in SimpleExoPlayer and
  SimpleDecoderVideoRenderer.

Subject: [PATCH 728/807] Merge consecutive segments for downloading.

This speeds up downloads where segments have the same URL with different
byte ranges. We limit the merged segments to 20 seconds to ensure the download
progress of demuxed streams is roughly in line with the playable media duration.

Subject: [PATCH 729/807] Propagate end of stream received from
 `OnFrameRenderedListener`

Previously the renderer EOS (aka last frame rendered), was reported as soon
as the last encoded frame was queued in the codec renderer.
This leaded to EOS reported too early.

Subject: [PATCH 730/807] Parse channel count and sample rate from ALAC
 initialization data

Also remove the "do we really need to do this" comment for AAC.
Parsing from codec specific data is likely to be more robust, so
I think we should continue to do it for formats where we've seen
this problem.

Subject: [PATCH 744/807] Fix byte order for HDR10+ static metadata

The implementation of writing HDR10+ static metadata assumed that the
application would use default (big endian) byte order for this metadata but
MediaCodec expects the order to match the specification CTA-861.3.

Subject: [PATCH 751/807] Reconfigure audio sink when PCM encoding changes

Note:
- Fixing this uncovers another bug in how audio processor draining
  works, so the test playlist still doesn't play correctly after this
  change.
- Once we reconfigure the audio sink based on the ExoPlayer Format
  rather than the codec MediaFormat in a later change, this change can
  be reverted.

Issue: #6601

Subject: [PATCH 752/807] Add testutils as test dep of library-core module

The current workaround seems to cause compilation errors inside the
testutils module in Android Studio. This seems to fix them.

This doesn't introduce a circular dependency because it's only
the tests in library-core depending on testutils.

 potentially blocking.

They are all marked with a JavaDoc comment and the @WorkerThread annotation
which is useful if apps are using threading annotations. All other public
methods in the same classes are marked with @AnyThread to avoid the impression
we forgot to annotate them.

- Change flags to a boolean.

Subject: [PATCH 768/807] Fix audio processor draining for reconfiguration

When transitioning to a new stream in a different format, the audio
processors are reconfigured. After this, they are drained and then
flushed so that they are ready to handle data in updated formats for the
new stream.

Before this change, some audio processors made the assumption that after
reconfiguration no more input would be queued in their old input format,
but this assumption is not correct: during draining more input may be
queued. Fix this behavior so that the new configuration is not referred
to while draining and only becomes active once flushed.

   * Make showing and hiding player controls accessible to TalkBack in
     `PlayerView`.
   * Rename `spherical_view` surface type to `spherical_gl_surface_view`.
+  * Make it easier to override the shuffle, repeat, fullscreen, VR and small
+    notification icon assets
+    ([#6709](https://github.com/google/ExoPlayer/issues/6709)).
 * Analytics:
   * Remove `AnalyticsCollector.Factory`. Instances should be created directly,
     and the `Player` should be set by calling `AnalyticsCollector.setPlayer`.

Subject: [PATCH 783/807] Use peak rather than average bitrate for HLS

This is a minor change ahead of merging a full variant of
https://github.com/google/ExoPlayer/pull/6706, to make
re-buffers less likely.

Also remove variable substitution when parsing
AVERAGE-BANDWIDTH (it's not required for integer attributes)

Subject: [PATCH 787/807] Refactor ExtractorInput javadoc about allowEndOfInput

This parameter is a little confusing, especially as the behaviour
can be surprising if the intended use-case isn't clear. This change
moves the description of the parameter into the class javadoc,
adds context/justification and slims down each method's
javadoc to refer to the class-level.

Related to investigating/fixing issue:#6700

  * Provides data to be consumed by an {@link Extractor}.

+ *   <li>The {@code read()} and {@code skip()} methods provide {@link InputStream}-like byte-level
+ *       access operations.
+ *   <li>The {@code read/skip/peekFully()} and {@code advancePeekPosition()} methods assume the user

+ * </ul>
+ *
+ * <h4>{@link InputStream}-like methods</h4>
+ *
+ * <p>The {@code read()} and {@code skip()} methods provide {@link InputStream}-like byte-level
+ * access operations. The {@code length} parameter is a maximum, and each method returns the number
+ * of bytes actually processed. This may be less than {@code length} because the end of the input
+ * was reached, or the method was interrupted, or the operation was aborted early for another
+ * reason.
+ *
+ * <h4>Block-based methods</h4>
+ *
+ * <p>The {@code read/skip/peekFully()} and {@code advancePeekPosition()} methods assume the user
+ * wants to read an entire block/frame/header of known length.
+ *
+ * <p>These methods all have a variant that takes a boolean {@code allowEndOfInput} parameter. This
+ * parameter is intended to be set to true when the caller believes the input might be fully
+ * exhausted before the call is made (i.e. they've previously read/skipped/peeked the final
+ * block/frame/header). It's <b>not</b> intended to allow a partial read (i.e. greater than 0 bytes,
+ * but less than {@code length}) to succeed - this will always throw an {@link EOFException} from
+ * these methods (a partial read is assumed to indicate a malformed block/frame/header - and
+ * therefore a malformed file).
+ *
+ * <p>The expected behaviour of the block-based methods is therefore:
+ *
+ * <ul>
+ *   <li>Already at end-of-input and {@code allowEndOfInput=false}: Throw {@link EOFException}.
+ *   <li>Already at end-of-input and {@code allowEndOfInput=true}: Return {@code false}.
+ *   <li>Encounter end-of-input during read/skip/peek/advance: Throw {@link EOFException}
+ *       (regardless of {@code allowEndOfInput}).

Subject: [PATCH 795/807] Fix mdta handling on I/O error

An I/O error could occur while handling the start of an mdta box, in
which case retrying would cause another ContainerAtom to be added. Fix
this by skipping the mdta header before updating container atoms.

Subject: [PATCH 796/807] MatroskaExtractor naming cleanup

- Change sampleHasReferenceBlock to a block reading variable, which is
  what it is (the distinction didn't matter previously, but will do so
  when we add lacing support in full blocks because there wont be a 1:1
  relationship any more.
- Move sampleRead to be a reading state variable.
- Stop abbreviating "additional"

Subject: [PATCH 797/807] MatroskaExtractor naming cleanup II

- Remove "lacing" from member variables. They're used even if
  there is no lacing (and the fact that lacing is the way of
  getting multiple samples into a block isn't important).

Subject: [PATCH 801/807] MatroskaExtractor: Constrain use of sample state
 member variables

This change constrains the use of sample state member variables to
writeSampleData, finishWriteSampleData and resetWriteSampleData.
Using them elsewhere gets increasingly confusing when considering
features like lacing in full blocks. For example sampleBytesWritten
cannot be used when calling commitSampleToOutput in this case
because we need to write the sample data for multiple samples
before we commit any of them.

Issue: #3026

Subject: [PATCH 802/807] MatroskaExtractor: Support lacing in full blocks

Caveats:

- Block additional data is ignored if the block is laced
  and contains multiple samples. Note that this is not
  a loss of functionality (SimpleBlock cannot have block
  additional data, and lacing was previously completely
  unsupported for Block)

- Subrip and ASS samples are dropped if they're in laced
  blocks with multiple samples (I don't think this is
  valid anyway)
