Setting the target conpatibility only seems to work for Java. Added the
equivalent Kotlin config options to the docs.

Also configure the FFmpeg context to ignore errors as far as possible (this

ExoPlayer methods must not be called from any thread besides the specified
app thread. Therefore we shouldn't use them here. Using a regular Handler
instead is fully equivalent.

This also applies when seeking or transitioning to unprepared media, which
isn't clear from the current documentation.

DataSpec.FLAG_ALLOW_CACHE_FRAGMENTATION is added to indicate to the
cache when fragmentation is allowed. This flag is set for progressive
requests only.
To avoid breaking changes, CacheDataSink defaults to ignoring the flag
(and enabling fragmentation) for now. Respecting the flag can be
enabled manually. DownloaderConstructorHelper enables respecting of
the flag.

We currently forget whether a source is seekable at re-preparation. This was
implemented intentionally this way under the assumption that we really can't seek
until we have loaded the seek map again. However, seek operations are only
allowed after a media period is prepared. So there is no harm in remembering
whether a source is seekable.
This problem currently prevents reusing ClippingMediaSources with
ExtractorMediaSource and a non-zero start clip position.

ExoMediaCrypto.requiresSecureDecoderComponent() is removed, and
FrameworkMediaCrypto.forceAllowInsecureDecoderComponents is made
public to allow determining whether a secure decoder is required
to be implemented in MediaCodecRenderer.

There were some edge cases in which we'd forget to release DRM
sessions. For example if we read a format and acquired a
pendingDrmSession (in onInputFormatChanged), then immediately
read another format and overwrote pendingDrmSession, we'd
forget to release the one that's been overwritten.
This change hopefully makes release much clearer. We keep a list
of all drm sessions we're currently holding. Whenever we update
either drmSession or pendingDrmSession, we release any other
sessions that are in the list.

The window object is used without being filled with data. This used to work
well for most cases as the same live stream is sending regular updates and the
first update is almost never used if it's not the first item in a playlist.
It causes problems when the first timeline update of a live stream is actually
used for playback (e.g. when the live stream is lazily prepared in a playlist
and played first).

[Problem]
We drop matching control codes even if they are not received on
consecutive frames.
The specification says
"(4) If the first transmission of a control code pair passes parity,
it is acted upon within one video frame. If the NEXT frame contains
a perfect repeat of the same pair, the redundant code is ignored."
Keyword is the NEXT. The frames must arrive immediately after
each other.
See https://www.law.cornell.edu/cfr/text/47/79.101
[Solution]
Set an additional flag when any data is processed. Control code
duplication checks should be limited only for the first control
byte pairs processed after any control code.
[Test]
Sarnoff tests have equivalent CEA708 and CEA608 Streams.
This is the initialization part of mitigating issue #4253. The
remaining work is on the writing side, and is simply a case of
having startFile return File instances that are sharded into
sub-directories. We still need to decide what scheme we want
to use for doing that.

Calls to File.length() can be O(N) where N is the number of files
in the containing folder. This is believed to be true for at least
FAT32. Repeated calls for the same file tend to be faster,
presumably due to caching in the file system, however are still
surprisingly expensive. Hence minimizing the number of calls is
preferable.

They are not longer needed anywhere, are error-prone (because of threading
requirements), and complicate testing and using MediaSources without a player.
PiperOrigin-RevId: 227871157
We currently either use the app thread returned by the player or the thread
the commands are called on depending on whether the media source is already
prepared or not.
This change lets the application decide which callback thread to use. As a
side effect, we also don't longer need access the player instance passed to
MediaSource.prepare.
