Use Mp4WebvttDecoder for WebVTT content in DASH MP4 containers · 7b8895d6
This was broken by https://github.com/google/ExoPlayer/commit/74a9d8f680995f2096c59fde6cd1ef6e85bb4d55 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). Issue: #7985 PiperOrigin-RevId: 334771672
