Resuming:
* maybe OFFSET could be specified for each demuxer
* width/height could be specified by a size option calling av_parse_video_size()
* framerate could be specified by a framerate option calling
av_parse_video_rate()
* av_get_pix_fmt() result needs to be checked
Since av_parse_video_size/rate fails for 0x0 or 0/0 you may need to do
a further check when such values are allowed (for example in the V4L2
demuxer), for example you could set the default to "auto" meaning 0/0
which is also more explicit and thus better from the usability POV.
