ibaker 8b9bf5e7cd Add DASH CEA-608 playback test 
This was generated by combining the existing `ts/bbb_2500ms.ts` test
asset and a temporary `.srt` file using
https://cloud.google.com/transcoder/docs/how-to/captions-and-subtitles

This doesn't directly reproduce the problem fixed by
7ca26f898d,
because the CEA-608 subs are structured differently to the stream I
discovered the problem with (from Issue: androidx/media#887). However this test
does fail if that fix is reverted after
486230fbd7.

I'm also not able to repro the character duplication reported in
Issue: androidx/media#887 by just changing the manifest in this CL. I'm not yet
sure on the exact differences between the stream provided on GitHub
and this stream.

This stream does provide some regression protection, because it
currently fails with 'new' subtitle parsing
(`DashMediaSource.Factory.experimentalParseSubtitlesDuringExtraction(true)`),
though I'm not sure on the exact reason for that yet.

ExoPlayer DASH module

Provides support for Dynamic Adaptive Streaming over HTTP (DASH) 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-dash: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 DASH media items added to ExoPlayer in its default configuration. Internally, DefaultMediaSourceFactory will automatically detect the presence of the module and convert a DASH MediaItem into a DashMediaSource for playback.

Similarly, a DownloadManager in its default configuration will use DefaultDownloaderFactory, which will automatically detect the presence of the module and build DashDownloader instances to download DASH content.

For advanced playback use cases, applications can build DashMediaSource instances and pass them directly to the player. For advanced download use cases, DashDownloader can be used directly.
