- Parse all attributes that may exist in either the AdaptationSet or
in the child Representation elements at both levels.
- Correctly infer TYPE_TEXT for Representation elements whose mimeType
is application/mp4 and whose codecs attribute indicates a known text
codec type.
Issue: #689
Remove MPEG TS stream filtering based on AudioCapabilities.
Pass AudioCapabilities to MediaCodecAudioTrackRenderer so it can choose between
passthrough/raw and decoding for AC-3 tracks.
- Generalize rendererEnabledFlags to be selected track indices through
ExoPlayerImpl/ExoPlayerImplInternal.
- Selecting an out-of-bound track index (e.g. -1) is equivalent to
disabling a renderer prior to the generalization.
- A prepared TrackRenderer that exposes 0 tracks is equivalent to a
TrackRenderer in the STATE_IGNORE state prior to the generalization.
Issue #514.
On NVIDIA Shield, recreated passthrough AudioTracks have incorrect playback head
positions, due to shared state with the previously destroyed passthrough
AudioTrack. Calling AudioTrack.flush() before AudioTrack.release() ensures this
state is cleared.
This is a safe change so I have not made it a device-specific workaround. The
combined time for flush and release is less than 10 ms (with flush normally
taking less than two ms).
Everything I've seen that uses ExoPlayer sets it to true, and
setting it to false is poorly supported / likely to result in
bad initial A/V sync after each seek.
Both FragmentedMp4Extractor and WebmExtractor now invoke seekMap() with
SeekMap.UNSEEKABLE if there isn't an index in the stream, so DASH playbacks
will end up printing this warning every 5 seconds or so. This is obviously
not desirable, so this CL just removes the warning! The alternative would
have been to print a warning if the value is anything other than UNSEEKABLE,
but it doesn't really seem worth it.
This is useful to allow playback of individual segments from a
DASH stream as regular fmp4 files. These segments don't typically
contain a segment index. For playback to start, we need to invoke
seekMap with the UNSEEKABLE index. We do this if we haven't seen
a segment index when we encounter an mdat box (if one were present,
it would have been located earlier than this point).
1. [Cleanup] Remove unused Track types, including TYPE_TIME_CODE.
2. Add subtitle track type, which is different to the existing text type.
3. Set duration on the media formats for text and subtitle tracks. This
was causing the player to report unknown media duration for mp4 files
containing such tracks.
4. Make TextTrackRenderer do the right thing when not started.
Issue: #635
- Make UnrecognizedInputFormatException public so the app can more easily handle
it when it is propagated to onPlayerError.
- Format the description using the simple class names for the extractors.
- Don't retry loading after it's thrown, but just throw immediately.
- ExtractorSampleSource takes an array of extractors to test for suitability.
- Extractors now implement a sniff() method that returns whether they can
extract samples in the input stream's format.
- Switch demo app samples to use format detection.
Issue: #438
1. Fix seeking in test2.mkv by handling non-default timescale
after duration.
2. Fix handling of missing cues in test6.mkv by allowing playback
to continue (but all seeks will reset to t=0).
Issue #631
The ID_SEGMENT can only be read once, as seeing the element a second time is
assumed to indicate that the file contains multiple segment elements (which is
not supported).
This change allows the element to be read twice if it is at the same position,
so that retrying loading from the start can succeed.
1. Workaround for decoders that fail to handle the END_OF_STREAM flag.
2. Revert processing of final output buffer if it's non-empty. This
introduced another bug (#596)

Issue: #596
SubtitleLayout no longer trigger re-layouts of the view hierarchy.
Instead, the SubtitleLayout just invalidates itself. This is made
possible by making SubtitleLayout a regular View that draws each Cue
directly onto the canvas, rather than having SubtitleLayout be a
ViewGroup with a child View for each Cue.
The SubtitleLayout is now properly aligned with the surface.
This means the subtitles remain on top of the video in portrait
mode, rather than being huge and below it.
Prior to this change, there was a bug where playback would
fail with the following steps:
1. Start playback.
2. Pause playback.
3. Disable all renderers.
4. Enable at least one renderer.
5. Resume playback.
The new logic assumes that an input format change will be
followed by an output format change, but I think this is
pretty much guaranteed. If this weren't to happen then the
new pixel aspect ratio wont be picked up, but I think it's
extremely unlikely (it would require the format to stay
exactly the same except for the pixel aspect ratio, which
would be bizarre).
1. An optional U+FEFF BYTE ORDER MARK (BOM) character.
2. The string "WEBVTT".
3. Optionally, either a U+0020 SPACE character or a U+0009 CHARACTER
TABULATION (tab) character followed by any number of characters that
are not U+000A LINE FEED (LF) or U+000D CARRIAGE RETURN (CR) characters.
4. Exactly one WebVTT line terminators to terminate the line with the file
magic and separate it from the rest of the body.
Issue: #580
Improve Mp4Extractor test.
Add support for Xiph lacing in Matroska files.
Add support for EBML lacing in Matroska files.
Handle the initial sticky intent for HDMI audio plug.
An accumulation of several fixes:
1. Change to HlsExtractorWrapper is just a move + documentating
things that were already true + adding a precondition in the
configureSpliceTo method.
2. Change in HlsSampleSource.readData ensures that configureSpliceTo
and hasSamples aren't called on an extractor that isn't prepared.
3. The other change in HlsSampleSource ensures the correct "previous"
TsChunk is used. If a TsChunk fails to load and is replaced, the
previous chunk should be the one before that whose load completed
successfully.
4. Determine switchingVariantSpliced based on the actual format of the
previous chunk, so it's set correctly in the case of a TsChunk load
failure and subsequent replacement.
This fixes the case where we need to switch from one variant to
another during preparation, having loaded zero samples, because
the first chunk for that variant gave us a 404 error. In this
case the first extractor will have no samples, and there will
be a second extractor that does.
