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)

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.

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.

The MediaMetricsListener currently just looks at the mime type and
doesn't use the inference based on the URI if no mime type is set.

Also change default type to OTHER to avoid classifying streams from
URLs without clear file extension as progressive.

Adaptive video and audio selections will be limited to formats with
the same level of DecoderSupport and HardwareAccelatationSupport, unless
specifically allowed by new flags.

If different levels of decoder support are available, prefer primary
over fallback decoders and hardware-accelerated over software decoders
(in this order). For video, also prefer more efficient codecs, if both
are supported by hardware-accelerated primary decoders.

This change moves the video track selection to the generic
selection method introcuced for audio and text. This ensures
we can apply the same criteria for fixed and adaptive video
track selections. Implicitly, this reorders the preferences
for adaptive tracks to give non-quality preferences (like
preferred MIME type or preferred role flags) a higher priority
than number of tracks in the selection.

This does currently only happen by chance in replaceStream (called from
enable) if the stream previosly played read until C.TIME_END_OF_SOURCE.

enable already makes all changes done in resetPosition (except resetting
the reading position), so it's less error-prone and makes the intention
clearer if the same code is called from both enable and resetPosition.

The effect of this bug was quite limited because the numerical value
of readingPositionUs was only relevant for periods with changing
durations and server-side inserted ads.

The app will be notified about fallback using a callback on
Transformer.Listener. Fallback may be applied separately for
the audio and video options, so an intermediate internal
FallbackListener is needed to accumulate and merge the track-specific
changes to the TransformationRequest.

We currently run (almost) the same code for all track types.
De-duplicate this by using a single method that takes functional
interfaces for track-type dependent logic.

This has the benefit that all track-type dependent logic is
contained within their subclasses and the generic logic doesn't
need to make any assumption about the eligibility of tracks for
selection or adaptation, and doesn't need to access Parameters.

Make this change for audio and text only for now. Video can
be updated in a subsequent change.

This value is the default used by widevine_test at

PiperOrigin-RevId: 421781437

The existing wording would be correct if prefixed with
"Returns false if [...]", but it seems confusing to a document a boolean
method in terms the condition it returns false - so I reworded it in
terms of when it returns true.
