I am mildly interested in this, but since I live in
PAL-country, I don't know enough about it.
Could you explain how the flag is useful for you?
(I simply don't understand why you don't want to output
the 24fps video with 24fps, but I am obviously missing
something. Or is the original mixed telecine-progressive
material? Then the next sentence is even more important,
because I don't think we have such a sample for h264.)
Please provide a sample.
