The browser cannot play this type: no decoder plays the configured type, or a decoder can't decode the stream's codec.
No decoder in this browser plays the frame's kind and type; it was dropped.
A media fragment arrived before any init segment, or an encoded chunk before any key frame, and was dropped.
The browser rejected a piece (decode error, or out of buffer space after trimming).
Media arrived faster than it could be played, or while no element was attached, and the oldest was dropped.
Why playout reported a problem.
