`subtitle` is only guaranteed to be non-null if
`nextSubtitleEventIndex != C.INDEX_UNSET`. The null check added in
0efec5f6c1
was too early.

This was broken by 74a9d8f680
because DashManifestParser switched to setting Format.sampleMimeType to
text/vtt while SubtitleDecoderFactory was still expecting
application/x-mp4-vtt. This change teaches SubtitleDecoderFactory to
check both Format.containerMimeType and Format.sampleMimeType.
I'll investigate a follow-up change to remove
MimeTypes.APPLICATION_MP4VTT completely (it's currently still used in
AtomParsers).

In the test, a real instance of SimpleExoplayer plays two identical Mp3 files.
The GaplessMp3Decoder will write randomized data to decoder output on receiving
input. The test compares the bytes written by the decoder with the bytes
received by the AudioTrack, to verify that the trimming of encoder delay/
padding is correctly carried out.
Test mp3 has delay 576 frames and padding 1404 frames. File generated from:
ffmpeg -f lavfi -i "sine=frequency=1000:duration=1" test.mp3
This change needs robolectric version 4.5, which is not currently released (2020 Sep 30).

When I moved ParsableByteArray#data behind a getter I replaced some
assignments with calls to reset(byte[]):
ce2e6e2fd6
reset(byte[]) deliberately sets `limit` to `data.length`, in order to
handle cases that were reassigning `data` but not updating `limit`.
However OggPacket was already using `limit` to track where to write
'new' data into the array, so changing `limit` to `data.length` caused
us to try and write new data beyond the end of the array.
I looked at other uses of reset(byte[]) in ce2e6e2fd6
and condluded the only other usage in MatroskaExtractor is legit and
shouldn't be updated like this (because MatroskaExtractor previously
*wasn't* correctly updating/maintaining `limit`).

Non-realtime AudioTrack playback speed was not taken into account when
extrapolating the old mode's position, causing the position not to
advance smoothly.
This should be a no-op when not using AudioTrack playback params for
speed adjustment.

On receiving a fetch error for an ad that would otherwise play based on an
initial/seek position, the pending content position wasn't cleared which meant
that position reporting was broken after a fetch error. Fix this by always
clearing the pending position (if there was a pending position that will have
triggered the fetch error).
Also deduplicate the code for handling empty ad groups (fetch errors)
and ad group load errors.

Remove the SynchronousMediaCodecBufferEnqueuer interface
since we only keep the AsynchronousMediaCodecBufferEnqueuer
implementation.

Retry AudioTrack init and write for 100ms before
giving up and aborting playback.
This was tested by throwing every 2 init/write and
making sure playback did not stopped.

This issue has been observed on a test app stress
testing setEndOfStream.
The issue has not been observed on ExoPlayer,
probably due to timing differences, but it is fixed
preventively.

This seems to be an exact copy of sample.adts. Update the test to use
the same sample but just output to a different dump file.

The shrinking didn't mention that users of the existing
ProgressiveMediaSource need to pass in ExtractorsFactory.EMPTY to the
SimpleExoPlayer.Builder as well.
Also updated the release notes to mention the changed shrinking
guidance.

We have a workaround for uneven sample stream durarions in playlists that
assumes a renderer allows playback if it's reading ahead or waiting for
the next stream.
652c2f9c18 changed this logic to no longer require to
wait until the next stream is prepared due to a change in how we advance
media periods in the queue. However, the code falsely still requires the
next stream to exist (even if it's not prepared). This can cause a stuck
buffering state when the difference in the duration of the streams is more
than what we buffer ahead because we never create the next stream in such
a case.
Note: DefaultMediaClock.shouldUseStandaloneClock has roughly the same logic
and also doesn't require the next stream to be present.
Also fix a test that seemed to rely on this stuck buffering case to test
stuck buffering detection. Changed the test to not read the end of stream
to ensure it runs into the desired stuck buffering case.

This allows to use the same logic from multiple places without duplicating
it, encapsulates in its logical place, and allows to change the available
segments based on the new availabilityTimeOffset value.
The overall effect of this change is a no-op.
