> I still don't understand how I can reproduce the problem: Is there an
input sample and command line for which I can reproduce A/V desync or is
this ticket only about a warning that a third-party tool shows?
1. You get a negative start_time with ffprobe for format and audio stream
2. With the segment muxer the first segment always exceeds segment
duration (in spite of forced key frames etc.)
3. asetpts=PTS-STARTPTS does not make the audio start at 0 as it's
supposed to do
