tonihei 1044cfe82a Turn on HLS chunkless preparation by default.
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.

Release notes

1.0.0-alpha01

AndroidX Media is the new home for media support libraries, including ExoPlayer. The first alpha contains early, functional implementations of libraries for implementing media use cases, including:

  • ExoPlayer, an application-level media player for Android that is easy to customize and extend.
  • Media session functionality, for exposing and controlling playbacks. This new session module uses the same Player interface as ExoPlayer.
  • UI components for building media playback user interfaces.
  • Modules wrapping functionality in other libraries for use with ExoPlayer, for example, ad insertion via the IMA SDK.

ExoPlayer was previously hosted in a separate ExoPlayer GitHub project. In AndroidX Media its package name is androidx.media3.exoplayer. We plan to continue to maintain and release the ExoPlayer GitHub project for a while to give apps time to migrate. AndroidX Media has replacements for all the ExoPlayer modules, except for the legacy media2 and mediasession extensions, which are together replaced by the new media3-session module. This provides direct integration between players and media sessions without needing to use an adapter/connector class.
