I've never heard the term "MMCO" yet. So your reply is a bit
over the top of my head. But if it's possible somehow to detect
seekable frames simply by parsing the bitstream, then of course
that would be the ultimate solution.
Would you mind going into a bit more detail on how that would
be done technically? This is something I could use in my own (non
libav related) projects, too. So I find this quite interesting.
