Re: glav error opening .avi file

Hallo,

my fault. You have a .wav file an need to add that to the video file.
So you can skip this command: cat audio.wav | mp2enc -v 2 -V -o sound.mp2

And just use that command:
lavaddwav video_without_sound.avi audio.wav output.avi

I hope that works.

Regards, Bernhard
