ffmpeg can transcode both audios on "dual avi"?

[CactusMan]

Hello.

I need to use ffmpeg to do this job to automate this task with a lots of AVI. Need some help here because so far, my searchs on net only talks about the command "map" from ffmpeg to one audio only. The docs from ffmpeg lacks of command examples too.

I guess you have read http://howto-pages.org/ffmpeg/#map ?

Yes I already read it yesterday. But none answer my questions. It's not states if there is or there isn't the possibility of transcoding both audios or not. This is not the most important question... I can transcode two audios separated. My doubts is how ffmpeg works with dual audio. Can mux or can not?

Make sure you have a recent version of ffmpeg - different versions of ffmpeg accept different parameters.

This works with FFmpeg version 0.9:

ffmpeg -i input.vob -map 0:0 -map 0:1 -map 0:2 -map 0:3 -map 0:4 -vcodec libx264 -vb 2000k -acodec ac3 -ab 224k test.avi

'input.vob' is a file ripped from a DVD (with 1 video and 4 audio streams). ffmpeg outputs an AVI with 1 h264 video stream and 4 ac3 audio streams.
