You did not show us the complete, uncut console output as is strongly suggested here for every request.

[FFmpeg-user] Interleaving problem
Hi, I need a "good" interleaved mpeg-ts media. I have found that the ffmpeg is unable to re-interleave the input data. As can be seen on the packet list below, the audio and video packets are not interleaved well. There are several video packets and several audio packets. Is it possible to force ffmpeg to mix the packets better? Command: ffmpeg -i input.ts -max_delay 100 -c:v mpeg1video -c:a mp2 -ac 1 -vf showinfo -af asetnsamples=n=100,ashowinfo -f mpegts -max_delay 100 out.ts The options (max_delay, asetnsamples) have no positive effect in this case.
