- Added logic to parse media duration from the `mdhd` box for accurate frame rate calculation. - Fallbacks to track duration from `tkhd` when `mdhd` contains invalid or missing data. - Avoids incorrect frame rate calculations in MP4 files with an edit list (`elst`) box. - Adds frame rate calculations for partially fragmented MP4 files. - Verified accuracy with tools like `mediainfo` and `ffprobe`. Issue: androidx/media#1531 **Note**: The slight difference in frame rate values in dump files that aren’t MP4s with an edit list or fragmented MP4s isn’t due to differences in `tkhd` and `mdhd` duration values (which should be identical for non-edited or non-fragmented files). Rather, it’s because they are calculated using different timescales. The `mvhd` box defines a global movie timescale, which is used for the track's `tkhd` duration. Meanwhile, each track’s `mdhd` box defines its own timescale specific to its content type, which we now use for more accurate frame rate calculation. PiperOrigin-RevId: 676046744
ExoPlayer SmoothStreaming module
Provides support for SmoothStreaming content in ExoPlayer.
Getting the module
The easiest way to get the module is to add it as a gradle dependency:
implementation 'androidx.media3:media3-exoplayer-smoothstreaming:1.X.X'
where 1.X.X is the version, which must match the version of the other media
modules being used.
Alternatively, you can clone this GitHub project and depend on the module locally. Instructions for doing this can be found in the top level README.
Adding a dependency to this module is all that's required to enable playback of
SmoothStreaming media items added to ExoPlayer in its default configuration.
Internally, DefaultMediaSourceFactory will automatically detect the presence
of the module and convert a SmoothStreaming MediaItem into a SsMediaSource
for playback.
Similarly, a DownloadManager in its default configuration will use
DefaultDownloaderFactory, which will automatically detect the presence of
the module and build SsDownloader instances to download SmoothStreaming
content.
For advanced playback use cases, applications can build SsMediaSource
instances and pass them directly to the player. For advanced download use cases,
SsDownloader can be used directly.
