Propagate elapsedRealtimeUs to the video renderer. This allows
the renderer to calculate and adjust for the elapsed time since
the start of the current rendering loop. Typically this is <2ms,
but there situations where it can go higher (normally when the
video renderer ends up processing more than 1 output buffer in
a single loop).
Also made variable naming more consistent throughout the package.
- Use native frame release timing in video renderer for
smoother video playback.
- Avoid unnecessary memory copy steps in audio renderer.
- Use non-blocking AudioTrack API.
This allows ManifestFetcher to both execute the initial
manifest load and be plugged into an ExoPlayer ChunkSource,
where it can be used for repeated manfiest refreshes during
live playback.
2. Common interface for manifest parsers.
- This effectively moves the common interface from the Fetcher level
(i.e. ManifestFetcher) to the Parser level (i.e. ManifestParser).
- The motivation here is to allow the implementation of components that
can work with a generic ManifestParser implementation.
- Add constants class. Currently housing a single lonely variable,
which is used generally throughout the library, and so no longer
nicely fits into a specific class.
- Rename a few other constants to add clear units.
- Made minor tweak to ExoPlayer documentation.
This paves the way for SegmentTemplate and SegmentList based
mpds, which will implement DashSegmentIndex directly rather than
parsing an index from the media stream.
- Define DashSegmentIndex.
- Make use of DashSegmentIndex in chunk sources.
- Define an implementation of DashSegmentIndex that wraps a SegmentIndex.
- Add method that will allow Representations to return a DashSegmentIndex
directly in the future.
- Add support for non-contiguous index and initialization data in media streams.
For the Webm case this isn't enabled yet due to extractor limitations.
- Removed ability to fetch multiple chunks. This functionality does not extend
properly to SegmentList and SegmentTemplate variants of DASH.
