I'm trying to merge two cd-s into 1 file and also boost sound volume 200%, I tried this using avconv tool, but I only got cd1 and without an boost in sound:
nohup avconv -i cd1.avi -i cd2.avi -vcodec libx264 -acodec libvo_aacenc -r 30000/1001 -vol 512 merged.mp4
I used same syntax as for ffmpeg, any ideas why it didn't work? I can't find documentation for -vol for avconv. and also info about merging files is scarce.
