Comment (by Cigaes):

 Replying to [comment:16 cehoyos]:
 > Why are you reencoding the output files of the segment muxer? I don't
 think this is supposed to work.

 There is no reason for it not to: the output of the segment muxer are
 normal files with proper timestamp, and that is all that is required of

 Of course, the transcode command line destroys the timestamps, and that is
 probably the cause of the error; {{{-copyts}}} should help; hopefully, the
 old bugs of the TS muxer with timestamps will not be a problem here.
