[FFmpeg-user] Interleaving problem

Tue Oct 8 22:04:18 EEST 2019

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.

Sample:
