Previously that was implicit, it was the passthrough dance:
- MimeTypes.getEncoding(inputFormat) did not
implement RAW MIME, so it was returning INVALID_ENCODING for PCM
- and allowPassthrough was returning
MimeTypes.getEncoding() != INVALID_ENCODING
- which was setting codecInfo.passthrough, and passthroughEnabled.
Thus Util.isEncodingPcm(encoding) is the opposite of
(MimeTypes.getEncoding(inputFormat) != C.ENCODING_INVALID)
This was rather implicit and brittle as anyone
could add support for audio/RAW in
MimeTypes.getEncoding and break PCM playback.
As a result make it explicit that allowPassthrough
must always return false in PCM.

The transition in EPII happens based on the duration of the periods, not
the windows. So use this duration in case they are not the same.
Also make sure to send the message at duration-1 because the playback position
at the duration is technically already the first position in the next item.
PiperOrigin-RevId: 294669335
This simplifies sending messages to the end of a stream. This was
already possible, but users needed to wait until the duration is known
before sending the message. This duration resolution can happen as part of the message position resolution.

- Replace tests specific to HTTP request headers with tests that

This is a preliminary step toward adding a DataSpec.Builder,
which is needed for sanity when adding DataSpec.customData.
The existing absoluteStreamPosition field is very error prone,
because anyone using a Builder to adjust the request position
will need to remember to adjust two values:
dataSpec
.buildUpon()
.setAbsoluteStreamPosition(x)
.setPosition(x)
.build();
Furthermore, the difference between position and
absoluteStreamPosition is irrelevant in nearly all cases. In
the core library, the difference is only relevant when initializing
AES encryption/decryption to write/read cache files.
Replacing absoluteStreamPosition with uriPositionOffset will
simplify the code block above to:
dataSpec
.buildUpon()
.setPosition(x)
.build();

Once we receive an update from a masked source, we first start the
preparation of an already pending period, and only then notify the
player of the new timeline. If the period prepares immediately inline,
the MediaPeriod.onPrepared callback arrives before the

and causes issues when the player tries to lookup information in the
timeline that doesn't exist yet.

We currently apply new parameter checkpoints from an absolute media

However, the media start time may change when unexpected discontinuities
happen (the start time doesn't actually change, but we change it to
correct for this discontinuity). This then invalidates the absolute
media time in the playback parameter checkpoints (which should have been
corrected as well).
Avoid this problem by also only applying the new start position
from the checkpoint. We don't have to save the start position anymore
because it will cancel itself out.
Also add some documentation and code clarification for improved

PiperOrigin-RevId: 290749201
There are a couple of problems with how positions in PlaybackInfo are set at
the moment:
1. PositionUs isn't allowed to be C.TIME_UNSET. This is prevented by always
resolving to the current default position if needed.
2. In some places a window position was used as a period position. Use correct
position resolution procedure.
3. When creating a placeholder position to restart playback, we used the first
period in a window, not the one where the default position is.
4. The start position for ads was in some cases set to 0 without checking
the ad resume position.

If an exception is thrown between updating the timeline and updating
the position in playbackInfo, the state may be inconsistent.
Exceptions are expected to be thrown while updating the player state
and we should handle such cases in a consistent way.
Similar to how we handle the same situation in seekToInternal,
the state is updated in a final block such that it gets updated to the
latest state even if an error occurs. Moving both the timeline and
position update together also ensures they always stay consistent.

This restructure moves all the position resolving code to a static method and
removes the dependency of the MediaPeriodQueue on having an up-to-date timeline.
Both steps allow simplified reasoning about the code as the static method can't change
the state of the player, and there is no risk the queue can use the wrong timeline.
These propoerties allow to fix a bug causing inconsistent states in a follow-up step.

All events issued from ExoPlayerImpl (i.e. Player.EventListener events) currently
try to use the media period data from the playing media period as set in the
playback thread queue. This is only correct as long as there no pending masking
operations in ExoPlayerImpl. That's why we currently disable this whenever the timeline
is empty or a seek is pending. Since adding all the playlist API methods to the player,
this is no longer the right choice. Moreover, we don't have a definite API that tells
AnalyticsCollector when a playlist API call has been handled (and we don't want to
have one).
We can fix this by always using the current Player position information as the source
of truth (instead of the media period queue). This is definitely more correct and also
works while a masking operation is pending. To fill in the additional information from
the media period queue, we can look up a matching media period. This may not be the
first one in the list if an operation is pending.
The new methods are similar to the previous tryResolveWindowIndex method, but:
1. They are always used (i.e. the current Player state is the main source of truth)
2. They also check the correct ad playback state, that was just ignored previously.

Doing so prevent Codec which is a big object with
JNI to be garbage collected.
As the codec can not be hold in the listener, there
is no way to call release, as it must be called on
the same codec.
As a result the release method is also removed.
The downside is that at runtime some callbacks may be
dropped but it should be a short transitive state.
This also simplifies lifecycle of the listener as
the client does not have to know if release needs
to be called or not.
An alternative would have been to hold a weak ref,

This method has two use cases:
1. Seeking. Calls are immediately preceded by a call to rewind(), and
the returned value isn't important unless it's ADVANCED_FAILED (i.e.
the caller is only interested in success and failure).
2. Advancing. The return value is important unless it's ADVANCED_FAILED,
in which case the caller wants to treat it as 0.
This change creates separate methods for each use case. The new seekTo
methods automatically rewind and return a boolean. The updated advanceTo
method returns 0 directly in cases where ADVANCED_FAILED was returned.
Arguments that were always hard-coded to true by callers have also been
removed.

Currently the following sequence of events happens at automatic period transitions:
1. Update queue (=release old playing period)
2. Disable unused renderers
3. Enable newly needed renderers
This order requires difficult to follow workarounds in AnalyticsCollector for all
events related to step 2 (disable renderers). The current media period has already
been advanced so can't be used. The current workaround saves the last known playing
media period that was published as part of a PlaybackInfo update in ExoPlayerImpl.
This works in most cases, but is inherently wrong because the published state in
ExoPlayerImpl may be completely unrelated to the updates happening on the playback
thread (e.g. if many other operations are pending).
Simplify and fix this problem by changing the order of the events above:
1. Disable unused renderers.
2. Update queue
3. Enable newly needed renderers.
This way the current playing media period can be used for both renderer disable
and renderer enable events, thus it's correct in all cases and the workaround
in AnalyticsCollector can be removed.

This optimization allows a ChunkSampleStream to output track
formats as soon as they're parsed during an InitializationChunk
load, rather than waiting until after the InitializationChunk
load is completed.
In DASH VOD, a single InitializationChunk typically loads the
moov and sidx atoms in that order. Hence for long form content
where the sidx is a non-trivial size, this may result in the
track formats being output a non-negligible period of time
sooner than was previously the case. This allows downstream
renderers to start codec initialization sooner, potentially
decreasing startup latency.
For a single test stream on a fast & stable network, this
pretty consistently reduced elapsed time until both audio and
video codecs have been initialized from ~0.5s to ~0.3 seconds
on a Galaxy S8. For 5 test runs without and with these patches,
the eventTime logged by EventLogger for the second decoder
init were:
Without (secs): 0.47 0.47 0.45 0.48 0.46
With (secs) : 0.32 0.33 0.34 0.31 0.40
PiperOrigin-RevId: 289845089
The current order of operations means that the Format is only passed
to the chunk's output after the DataSource has been opened. This
means that establishing the network connection and the downstream
renderers initializing their codecs are effectively serialized to
occur one after the other.
In the new order, the Format is passed to the chunk's output before
the DataSource has been opened. This allows the downstream renderers
to initialize their codecs in parallel with the network connection
being established, and hence latency at the start of playback is
reduced.

We currently have a currentMediaPeriodId and an activeSessionId that are more

Simplify this logic by using a single currentSessionId field and the respective

the same method to make it easier to reason about the code.
This change also fixes a subtle bug where events after a seek to a new window

As discovered whilst investigating #6798, there are cases
where these methods are not correctly. They were added as
convenience methods that could be overridden by concrete
DownloadService implementations, but since they don't work
properly it's preferable to require application code to
listen to their DownloadManager directly instead.
Notes:
- The original proposal to fix#6798 stored the state change
events in memory until they could be delivered. This approach
is not ideal because the events still end up being delivered
later than they should be. We also want to fix the root cause
in a different way that does not require doing this.

sense that a server might return 416 (which we don't consider
for blacklisting) if the segment is unavailable, rather than
the 404 (which we do consider for blacklisting) that we expect
when media segments are only specified using a URL.

The Download constructor considers it invalid to have a failure
reason if the download isn't in the failed state. Unfortunately,
calling DefaultDownloadIndex.removeAllDownloads when there's a
failed download will change the state without clearing the reason.
If the downloads are then read back from the DefaultDownloadIndex
we end up violating the Download constructor assertion.
This change clears the failed reason for any existing rows in the
invalid state, and also fixes the root cause that allows invalid
rows to enter the table in the first place.

- Make extractor output samples that are uniformly distributed
with respect to time, with a target of ~10 samples per second.
The old approach could in theory put every frame into its own
sample, which would be very inefficient downstream because we'd
need to pass them individually to MediaCodec. It could also put
data corresponding to a long duration of time into a single
sample (e.g. if the sample rate of the content is low), which
is bad downstream because we decide whether to set the decodeOnly
flag on a per sample basis. More generally, the new approach
is more predictable :).
- Stop using the WavSeekMap to get sample timestamps, and instead
calculate them directly from the number of frames output. It's
more obviously correct, particularly for data formats like IMA
ADPCM where we'll need to adjust the data prior to output.

In MatroskaExtractor, if the last cue time exceeds the duration
specified in the header, then we end up generating a negative
duration chunk as the last item in the SeekMap. We should probably
not do this, so drop it instead.
Note: Matroska does have a CueDuration element, but it's not used
in the one problematic file I've found.

Currently, resetting the internal state related to the codec in done in 4 places
in MediaCodecRenderer:
1. In the constructor to set some sensible initial default.
2. In flushOrReleaseCodec to reset state after flushing
3. In releaseCodec to reset state to default values for a released codec.
4. In initCodec to reset state to defaul values for a new codec.
There are actuall only two types of state reset operations:
1. Resetting state for a released codec, so that a new codec isn't influenced by
previous codecs.
2. Resetting state after flushing an existing codec. This is a subset of (1).
So to simplify the class, this change moves all state resets to two methods
corresponding to the two cases above.

Also change IcyInfo.rawMetatadata from String to byte[]
ICY doesn't specify the character encoding, and there are streams

We previously used Locale.fromLanguageTag and then toLanguageTag to automatically
filter out invalid tags and to replace deprecated tags. However, this only works
for API 21+.
This change does no longer rely on the platform methods and instead:
1. Keeps invalid tags as they are. This may help if developers rely on
non-spec-complaint language tags (for example, #6681).
2. Adds a list of deprcated tags and their modern replacements to our code
3. Normalizes some short codes that have been superseded by macrolanguage codes by
their macrolanguage equivalent.

which is format type dependent).

This avoids needing to jump through type paremeter hoops to create a
sub-classable Cue.Builder.
Cue should have a standard set of fields, because it will be
consumed by renderers that don't know what type it is. The
existing subclass fields are only used inside their respective
packages, so can be part of a wrapper object instead.
This lays the groundwork for converting Cue's multiple constructors
into a Builder pattern.

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)

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.

Refator to lift a method to create (and destroy) the OnFrameRenderedListenerV23() and split destroying the Handler from removing the MediaCodec onFrameRenderedListener to avoid double call to codec.setOnFrameRenderedListener()

Saves around 200 lines of code. High level overview:
- Rename SampleQueue to SampleDataQueue.
- Rename SampleMetadataQueue to SampleQueue.
This CL should not introduce behavior changes. The only significant
changes in synchronization should be:
+ Add synchronized keyword to isReady.
- Seems to be necessary.
+ Add synchronized keyword to SampleQueue.sampleMetadata.
- Before this change, SampleQueue.sampleMetadata could acquire the
SampleMetadataQueue lock three times in a single method call.
Other miscellaneous improvements:
+ Put all private methods at the bottom.
+ Move release() to the right category.

If LoadControl.shouldContinueLoading returns false and the renderers are not
ready for playback using the already buffered data, playback is stuck.
To prevent this situation, we always continue loading if the buffer is almost
empty. We already have a similar workaround for when
LoadControl.shouldStartPlayback returns false even if loading stopped.
Having both workarounds allows playback to continue even if the LoadControl
tries to prevent loading and playing all the time.

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.
