[FFmpeg-user] What does ffmpeg do when packs switch?

[Mark Filipak]

I guess I need some schooling...

What does ffmpeg do when packs switch from hard-telecine to 
soft-telecine right in the middle of a GOP?

Of course, a link would be a fine response, but I've not found such a 
link (and I've been researching this stuff for months).

I certainly hope that the answer isn't that ffmpeg doesn't care about 
it. I hope the answer isn't that ffmpeg just takes what the decoder 
outputs because in one case the decoder outputs 5 frames (3 frame 
pictures and 2 field pictures that are sequential, not concurrent) and 
in the other case the decoder output 4 frame pictures.

Regards, and Thanks,
Mark.
