if I understand correctly I should
1) patch the fps to 29.97 or 30
2) always disable progressive sequence (lavc always sets it)
3) leave progressive frame as is
4) every frame must have either TFF or RFF, so when they are not
set I should alternate them every two frames?
and what when TFF is always set?


Can someone confirm or correct?
A link to a complete explanation would help a lot, thanks.
