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).
If the manifest server response arrived after the player was released, the
renderer builder would set up renderers for a released player, causing an
exception to the thrown in the DASH case.
Also fix Issue #657
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).
