Comment (by dgillier):

 Ok, sorry I did not understand what testsrc is. So forget my comment on

 My understanding is that the segmenter don't create correct .mp4 segment,
 as they not readable by any player as is.
 I get correct (but perhaps they are not) .mp4 files by adding a ffmepg -
 in.mp4 -c copy -out.mp4 file second pass to the segmented files.

 The problem is, after the 24th -30min- segment file, the declared duration
 is wrong (negative) and you cannot navigate in the file.

 When I applied the same process (because the segmented .mp4 file are not
 readable) with video only files, the files duration is 0s.
 So yes it is basically the same problem, wrong duration (negative one for
 files with audio, 0 duration for file with just video)...
