ibaker b8c8ce0ee0 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). Issue: #7985 PiperOrigin-RevId: 334771672		2020-10-17 12:09:13 +01:00
