- It's not possible to determine a period's duration just from the
corresponding Period element in a DASH manifest. It's necessary
to look at the start time of the next period (or the duration of the
manifest for the last period) to determine how long a period is. We
don't currently do this in the parser, and hence set duration incorrectly.
We also set period start times incorrectly because we don't set it to
equal to sum of the durations of prior periods in the case where it's
not explicitly defined.
- We're currently propagating these (incorrect) values all over the place
through data-structures that we build when parsing the Period element.
- This CL removes this redundancy, storing only the start time of each
period in Period elements, and not propagating it elsewhere. It's then
used when required in DashChunkSource.
- Video track is always marked as adaptive, the resolution is
stripped out (since it's otherwise just set to whatever the
resolution of the first selected variant is), and the max
dimensions are set.
Issue #514
- Migrate demo app to use new APIs.
- Add multi-track support for ExtractorSampleSource case.
- Add multi-track support for SmoothStreaming use case.
The final step is to add support back for the DASH use case and
delete MultiTrackChunkSource. This is blocked on multi-period support
landing, in order to prevent a horrendous merge conflict. We also
need to update HLS to expose sensible track information.
Issue: #514
multi-track support upstream to the ChunkSource interface.
This change does not yet make use of the newly exposed APIs. This
will come in a subsequent CL.
Issue #514.
- 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.
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.
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
- 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
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.
1. Remove requirement for TrackRenderer implementations to report
current position, unless they are time sources.
2. Expose whether renderers have media to play. The immediate benefit
of this is to solve the referenced GitHub issue, and also to only
display the appropriate Audio/Video/Text buttons in the demo app
for the media being played. This is also a natural step toward
multi-track support.
Github issue: #541
This makes it so that it's no longer necessary to specify the number
of downstream renderers to HlsSampleSource, FrameworkSampleSource and
ExtractorSampleSource, by forcing the downstream renderers to register
with the SampleSource instances in their constructors. This eliminates
a common source of subtle client bugs where the passed value is incorrect.
- There's definitely potential for more code sharing in these
classes, but deferring for now.
- Also made no-scheme default to file://, and allowed smoothstreaming
URLs to be specified with or without the /Manifest suffix.
This also fixes a technical mistake where HlsChunkSource is fed
seekPositionUs=-1 when obtaining the first chunk. This is wrong,
but the usage of this variable within HlsChunkSource enforces that
the seek must stay within bounds, so we get away with it.
