SDK / exoplayer

This only affects playbacks using the
experimentalUseProgressiveMediaSourceForSubtitles method.

Also update the SingleSampleMediaSource instantiation to be more
similar, to try and highlight differences like this in future.

In some cases we need to update the PlaybackParameters at period
boundaries, for example when switching from live to VOD and live
playback speed adjustment was still active at the point of switching.

Currently, we send the update when the playing MediaPeriod changes in
EPII, which is slightly too late because the new speed gets only applied
after the entire existing AudioTrack buffer has been played out.

We can time the update slightly better by updating the values at the
point where we change the reading period. This makes the update slightly
too early because it also applies to all samples currently in the
decoder. But generally, this is a lot better because the time spent
in the decoder is likely to be considerably lower than the duration of
the AudioTrack buffer.

Note that this change isn't perfectly aligning to the period boundary,
but reduces the number of samples with the wrong speed to a minimum.
If we are getting around to add additional code that allows updating
the speed at exactly the boundary, it also needs to be triggered from
the reading period update, so the new code location is also helpful in
the future.

When I locally link to exoplayer source modules as described in the README and I
do this directly into a fig/citc client, I get an error saying
"missing_aar_type_workaround.gradle': 79: unexpected token: || @ line 79, column
29.". I can fix this by wrapping the expression in parenthesis (¯\_(ツ)_/¯).

I don't think this file lands in the public source tree, but if we want to
correct this, it may help someone from the team.

This CL can be ignored and reverted also.

This CL looks good? Just LGTM and Approve it!
This CL doesn’t look good? This is what you can do:
* Revert this CL, by replying "REVERT: <provide reason>"
* File a bug under go/error-prone-bug for category ErrorProneStyle if the change looks generally problematic.
* Revert this CL and not get a CL that cleans up these paths in the future by
replying "BLOCKLIST: <provide reason>". This is not reversible! We recommend to
opt out the respective paths in your CL Robot configuration instead:
go/clrobot-opt-out.

This was resolved in https://github.com/google/ExoPlayer/commit/081700f72b2a43e1e0d01a0130cf283c7d59b9bc where the
Video/AudioSamplePipeline call this method before calling
the FallbackListener.

(and a few other GH issues related to invalid RTP-Info header)

PiperOrigin-RevId: 423283017

Issue: google/ExoPlayer#9775

We got a few issues for this on GH already. Some RTSP servers do not provide
track timing in PLAY responses, or the timings are invalid.

Missing timing means the RTSP stream is not seekable. Added method to
1. Update the timeline that seek is not possible
2. Report read discontinuity so that playback can start from the beginning.

If the output sample MIME type is inferred from the input
but is not supported by the muxer, we fallback to transcoding
to a supported sample MIME type.
The audio and video renderers need to make sure not to select the PassthroughSamplePipeline for this case. Which sample MIME type
to choose is decided by the EncoderFactory.

PiperOrigin-RevId: 423272812

To avoid the `MediaPeriodQueue`to discard the reading period, we can set the next ad of an ad group early and then (possibly) only change it's duration once we receive the actual duration. This way we avoid a rebuffering as a result of the reading period being discarded.

The change also takes care to properly set ad break and their durations when we join the live stream at the moment when an ad is playing.

We currently only end sessions on Timeline updates if the associated media
is no longer in the playlist. But we should also end all sessions that are
finished as a result of the timeline update (similar to how this is done for
discontinuities). This issue was introduced by https://github.com/google/ExoPlayer/commit/394ab7bcfd53bc8ffb8d2e37a5aeb71fef04d13c

Links should use []() instead of ()[].

PiperOrigin-RevId: 423073748

We currently don't check which session is causing a network transfer
(it could be a preloaded item in a playlist). To clearly associate
network transfer data with sessions, we need to keep track of
transferred bytes and transfer time per session.

PiperOrigin-RevId: 422867845

We may fall back to a different sample MIME type because
a) the sample MIME type inferred from the input is not supported
by the muxer or b) no encoders are available for the the requested
sample MIME type.

PiperOrigin-RevId: 422849036

With this change, the MediaCodecAudioRenderer configures the MediaCodec
to not downmix audio only if spatialization can be applied. This way,
decoders who are downmixing by default are left doing so when
spatialization cannot be applied. The renderer re-initializes the codec
when spatialization properties change mid-playback.

TransformationRequest is otherwise immutable, so if we modify the
transformationMatrix in place (done before this cl) this may cause
confusing behaviour for apps when they reuse a TransformationRequest.

PiperOrigin-RevId: 422822916

Currently, we keep the values for dropped/played frames, audio underruns
and current formats from the last session, causing double reporting
of counters and wrong track change reasons for formats. All these
values should be reset when the active session is finished, so that the
new session can start from scratch.

PiperOrigin-RevId: 422798406

Currently, we always end the current session if onSessionFinished is
called. However, the finished session may not be the active one (for
example when discarding prebuffered items in a playlist). To make this
code more robust, we can save the active session id explicitly and only
end this session.

PiperOrigin-RevId: 422788542

After implementing fallback, it won't always be possible to
differentiate between muxer and encoder as the cause of an output
format not being supported.

This change adds more standard metadata fields to Cast metadata including the artwork URL that makes the cast device show the artwork in the Cast route dialog (https://screenshot.googleplex.com/uj4n4Jqd7it9bob) and the Cast device.

This change also discriminates between media with an audio MIME type and others. For audio MIME type the Cast metadata is set to MEDIA_TYPE_MUSIC_TRACK which changes the layout and shows artwork and additional audio meta data to be displayed (https://screenshot.googleplex.com/ASy3KDcsTdJDM2T).

This change enables the ImaServerSideAdInsertionMediaSource for multi-period content. The global ad playback state is split into pieces for each period and the window and period durations are calculated accordingly in the ServerSideAdInsertionTimeline.

For multi-period live content (DASH), the ad playback state is not set with this change. This is deferred to a follow up CL. Splitting is very tricky. For each timeline update the windowStartTimeUs may vary for some milliseconds relative to the start of the period.positionInWindowUs. This requires to either introduce some fuzzy logic or to choose a different approach than for multi-period VOD. Because mistakes within the playback states of subsequent moving live windows produces crashes, it seems sensible to defer this for now and keep this change in a separate future CL (unblock further work, easy to rollback).

In this state, live DASH stream are working and the ad overlay is placed over the player correctly bu the SDK. However, ads are not reported by the position discontinuity event. Similarly, the player.isPlayingAd() does never returns true when a ad period is playing.
