[FFmpeg-user] Several audio tracks encoding issue

[Andrey Aleksandrovich]

I have still no result :(

As it is mentioned there
http://ffmpeg.org/trac/ffmpeg/wiki/Encoding VBR (Variable Bit Rate) mp3 audio
the parameter -q:a:1 5 tells encoder (libmp3lame) to use "audio
quality" at value 5, which means ~120-150Kbps VBR.
But, the command:

$ ffmpeg -i v.avi -i a1.wav -i a2.wav -map 0:0 -map 1:0 -map 2:0
-q:v:0 3 -q:a:0 5 -q:a:1 5 final.avi

generates bad second audio track (32Kbps, instead of specified quality setting).
What's wrong? How to set this correctly?
