I'll try and figure these out and post back here if I do.
In the meantime, since this behavior affects input/output, it would be
nice if the "dup" functionality were moved to a libavfilter, so that
1) it could be more understandable and 2) others not using FFmpeg
would have access to it (call it "sanitize_video_input" or whatever
you like).
Cheers!
