To anyone ever reading this thread:
I don’t know if the things written here are true for analog video, I don’t know
about other software but a lot that was written here is certainly wrong when
thinking of FFmpeg, do not use it as gu
Mark,
"recurse" works if your timestamps are correct.
Carl Eugen said that, too. How could the timestamps be wrong?
Well, I think the timestamp isn't "wrong", but it's "not as you expect".
If a filter has two inputs and the input frames have different
timestamps, then what's the timestamp
Upon rereading this thread, I see an error early on. I correct it, below.

pdr0,
I think you're a champ.
I can tell you're academic. Well, in addition to engineering for 25 years, I also taught: For 3-1/2
years in the U.S. Air Force. and for 1/2 year at a university.
Give the students one good example. That's all it generally takes. Then, when they run into a
