The differences between advanced and main/simple profiles also complicate
the issue - for advanced profile there is a well-defined standalone
bitstream format, so I'd be tempted to have the codec decode that, and get
the demuxers to pull out any necessary extradata and put it into the
bitstream. For main and simple profiles the carriage of stream metadata is
format-dependent, so there's no obvious nice way to give it to the codec...
