- Admit we don't know the mime type (using unknown mime types) rather
than passing the container mime type.
- Pass the correct mime type for opus, vp9 and vp8, and remove the incorrect
container checks in the corresponding extensions.
- With this change, you can select from the individual video formats in
the demo app, as well as the regular "auto" (adaptive) track.
- DashRendererBuilder no longer needs to create MultiTrackChunkSource
instances for the multiple tracks to be exposed.
- 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.
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.
- 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.
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.
