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:

Maybe not only hls segmenter, you can try use -f segment
or just use three task process single every stream, maybe have same
result.
