In the case of MP4 containers, it looks like we will have a relatively simple
way to get the demux to detect a change and emit a new caps event to the
decoders downstream (since video resolution is mandatory in the container
metadata).  However, in the case of MPEG2 transport streams, the container
itself does not have information about video resolution.  The elementary
streams probably carry this information, but you would have to have
codec-specific code in the demux to parse into the video headers to find the
resolution.

I am not an expert in MPEG2 TS, but is there a way to get the video resolution
so that a new caps event can be sent by the demux?
