ibaker 7b8895d655 Use Mp4WebvttDecoder for WebVTT content in DASH MP4 containers
This was broken by 74a9d8f680
because DashManifestParser switched to setting Format.sampleMimeType to
text/vtt while SubtitleDecoderFactory was still expecting
application/x-mp4-vtt. This change teaches SubtitleDecoderFactory to
check both Format.containerMimeType and Format.sampleMimeType.

I'll investigate a follow-up change to remove
MimeTypes.APPLICATION_MP4VTT completely (it's currently still used in
AtomParsers).

ExoPlayer DASH library module

Provides support for Dynamic Adaptive Streaming over HTTP (DASH) content.

Adding a dependency to this module is all that's required to enable playback of DASH MediaItems added to an ExoPlayer or SimpleExoPlayer in their default configurations. Internally, DefaultMediaSourceFactory will automatically detect the presence of the module and convert DASH MediaItems into DashMediaSource instances 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.
