 > There may be gaps between timestamps. You still can not grasp the fact
 that interleave picks the least timestamp in each case and not some N-th
 frame.

 notice that it needs strictly monotonic increasing timestamps.



 Paul,

 A week ago in my very first "ffmpeg architecture question" I wrote: "I
 assume that frame numbers are assigned at the input of the filter chain as
 frames are encountered ... Is what I've written correct? Authoritative
 confirmation or correction of this architectural detail is desired."

 Later that day I wrote: "When (and where in the filter complex) does
 ffmpeg assign frame numbers? I would guess that ffmpeg assigns frame
 numbers (0 1 2 3...) at the input, based on the PTSs of the arriving
 frames. The alternative would be that ffmpeg defers assigning the 'next'
 frame number (n+1) to a frame only when the frame succeeds to the output
 (or a queue), but I don't think that's what ffmpeg does. Again, this is a
 very important architectural detail, and I seek confirmation from a
 developer (Paul?)."

 Note: "based on the PTSs of the arriving frames". Note: "I seek
 confirmation from a developer (Paul?)".

 Instead of supplying the necessary information, you attacked me and wrote
 that I didn't know anything and that I am a troll.
