Actually, I used clips with mp3 and didn't have to do anything. The 
video source is 24fps, but after it goes to mp4 and back to ts segments 
video frame timestamps are different a little bit: in original movie all 
video frame timestamps increase monotonically (by 3715 if I'm correct), 
but after conversion to mp4 they increase by 3730 3700 3730 3700, so 
that overall timing is the same, but difference between frames is not 
constant. In that case live http stream breaks after a couple of minutes 
of playback: video becomes very slow while audio plays normal.
