MPEG-2 Program Stream Muxing
on Apr 21, 2011 at 3:50:37 pm

I had a problem when i am trying to mux 2 sounds:

I do:

ffmpeg -i anime.aif -ar 22050 -ab 64k anime.mp2
ffmpeg -i bertrand.mp3 -ar 22050 -ab 64k bertrand.mp2

ffmpeg -fflags genpts -i anime.mp2 -ar 22050 -ab 64k -aq 500 -i bertrand.mp2 -ar 22050 -ab 64k -aq 500 -f vob final.mpg -newaudio

The two files anime.mp2 and bertrand.mp2 mux together in final.mpg but the sound quality is bad.

What can i do, please help me ???

This is really just putting two streams into one file, not mixing the two files together into one stream. AFAIK, FFmpeg will not mix two audio files into one stream. Have a look at SoX for a good solution to mix two together.
