increase audio volume durinng the encoding

Pierpaolo Gullˆa
Hi guys ,

I'm using ffmpeg for convert some avi to mpg with good result.
The only problem is that the audio volume is very low.

I use this oprion for encode the files:

ffmpeg -i /root/video/sorgenti/xvid_virtualdub/1-10minuti.avi -vcodec
mpeg2video -r 25.00   -aspect 4:3 -b 4000k -mbd rd -flags +trell -mv0
-cgop -cmp 2 -subcmp 2 -acodec mp2 -ab 192k -ar 48000 -ac 2 -s 720x576
-y  /root/video/compressi/ffmpeg_agency/mp2/xvid_virtualdub/1-10minuti.mpg



There is a command for increase audio volume?


Thanks for your help

Pierpaolo

If you grep the usage for "volume" you will see:

-vol volume         change audio volume (256=normal)

I did not try this, but I think that if you choose -vol 512 you will get
double the volume (+3dB ???)
