ExoPlayer supports DASH with multiple container formats. Media streams must be demuxed, meaning that video, audio and text must be defined in distinct AdaptationSet elements in the DASH manifest (CEA-608 is an exception as described in the table below). The contained audio and video sample formats must also be supported (see the sample formats section for details).
