Using chunkless preparation greatly improves start up time if the master playlist declares CODECS for the renditions. Hence, we turn this on by default as it benefits most well-defined HLS master playlists. The only known reason why developers may want to turn this feature off is when the renditions contain muxed closed-caption tracks that are not declared in the master playlist. So this change also updates the documentation and RELEASENOTES to point out this caveat. PiperOrigin-RevId: 413950036
ExoPlayer HLS module
Provides support for HTTP Live Streaming (HLS) 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-hls: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.
Using the module
Adding a dependency to this module is all that's required to enable playback of
HLS media items added to ExoPlayer in its default configuration. Internally,
DefaultMediaSourceFactory will automatically detect the presence of the module
and convert an HLS MediaItem into an HlsMediaSource for playback.
Similarly, a DownloadManager in its default configuration will use
DefaultDownloaderFactory, which will automatically detect the presence of
the module and build HlsDownloader instances to download HLS content.
For advanced playback use cases, applications can build HlsMediaSource
instances and pass them directly to the player. For advanced download use cases,
HlsDownloader can be used directly.
