 Replying to [comment:5 krs_vital]:
 > the first stream is copy of the main stream, but 1 and 2 is streams from
 encoder, i think therefore timestamps are differ, it can be seen in
 playlists by #EXTINF tag:

 > but why hls segmenter cut main stream by different timestamps?
 Maybe not only hls segmenter, you can try use -f segment
 or just use three task process single every stream, maybe have same
 result.
