If you writeing hls error, can you try to write mpegts again to check if the problem is hls problem or the stream problem? and maybe the problem is happened in the UDP stream ?

To make this a valid ticket please provide an input file that allows to reproduce and the command line you tested together with the complete, uncut console output.

comment:3 Changed 4 months ago by krs_vital

its not a stream problem, because in main udp stream sound works fine, and after restart ffmpeg sound apears to! this problem may appear on other streams and I can't figure out what it depends on.

I noticed that when there is a problem with the signal on the satellite, the probability of occurrence of this problem is very large

There is nothing you can do, the message is not meant for users of the ffmpeg command line utility.

Please explain how I can reproduce the "sound disappears" issue with the sample you uploaded by providing the command line you tested together with the complete, uncut console ouptut and reopen this ticket.
