Comment (by markfilipak):

 I'd like to make another comment. It's about the documentation.

 showinfo is in https://ffmpeg.org/ffmpeg-filters.html#showinfo. It says
 "pts
     The Presentation TimeStamp of the input frame"
 That is clearly untrue. Clearly, it's the decoder's output. But it's that
 misleading statement in the documentation that led me to conclude that
 FFmpeg has a bug.

 show_frames is in https://ffmpeg.org/ffprobe-all.html, but it's
 essentially undocumented.

 Oh, I'd also like to make a comment about "non-monotonic DTS". Today I
 again attempted to find a way to concat my 4 segments. I added "-muxdelay
 0" when I saw that having just "-copyts" didn't preserve timestamps. When
 I added "-muxdelay 0" I got many hundreds "non-monotonic DTS" notices.
 That does not seem reasonable.
