I m facing an issue with this link that I can't seem to resolve.

The m3u8 display either the video track or the audio track, but never both, though they exist.

I put the same command on 2 different shells and on one I get the audio track, or the video one on the other..

Question: Since I have seen a site properly using this link (I had audio and video on the jwplayer webplayer) how can I use ffmpeg (or any other program ) to grab both input and output them in a single file? Doesn't work either on SMPlayer

I tried to use -analyzeduration 1000M -probesize 1000M in ffmpeg parameters but it doesn't help
