The audio is sometimes choppy between segments.

It occurs very often. Do you know the reason of it?

I have changed -t flag on -hls_time and it works for me.

I'm also searching for an solution, but looks like it impossible by design if transcoding runs independantly

@GomZik Thanks for sharing! I will look into this document. Learning a lot here. The independent transcoding seems to be the issue. I did not know this when I started this project since I just wanted to learn about video encoding.

Best what I have done - it is transcoding audio separately using one ffmpeg command, but it also takes a lot amount of time for single media file (koef is something about 3x)
