tianyifeng 58a63c82aa Calculate HLS live playlist refresh interval accurately
Previously, we calculated the next playlist reload time by adding the target duration (or half of it, depending on whether there is a real update in the new playlist snapshot) from the last load completion time, which makes the reload interval as long as `targetDuration(or half of it) + lastLoadDuration`. While still complying to the standard that "the client MUST wait for at least the target duration before attempting to reload the Playlist file again", this could cause buffering when the playback position is close to the end of live window. This change is to calculate the reload interval accurately by not adding the term `lastLoadDuration`.

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.
