WMA Audio in AVI file

[windranger]

Hi,

I have an AVI file which has the audio encoded as Windows Media Audio (WMA); it plays on PC but it doesn't on a TV video player.

What I want to do is:
- demux the file into video and audio
- convert audio to mp3
- mux the new audio with the video

What tools would be needed for this and what are the steps to follow...?

I tried to extract audio with Vdub (File->Save WAV), but the wav file has no sound in it (although it has about 20Mb); I can't play it with any player (Winamp, etc) so it's not good.

Thanx

You can try

avidemux, open avi, under video choose copy and under choose mp3 and save as a new avi.

or if that wont work

ffmpeg command line version(put all files in same folder and run from the command prompt):
ffmpeg -i video.avi -vcodec copy -acodec mp3 -ab 128k newvideo.avi

and last

Try open the avi directly in goldwave or audacity beta and see if it can read the audio and then save as a mp3.

Thanks Baldrick,
But I'm on Windows and it seems ffmpeg doesn't have an installer... (it's just a file with a wierd "7z" extension!)

Try google for 7z....or use a gui for ffmpeg like WinFF(don't know if you can use the video copy mode then though).

Thanks Baldrick,

I tried with ffmpeg and it doeasn't work. I get the message attached from the command prompt...
Any ideas why this behavior..?

Try installing this: DivX WMA Audio
...then load the video in VirtualDub and try converting the audio to MP3 as normal there (with the video set to Direct Stream Copy, unless you want to convert that as well).

easy...use Avanti

Hi guys and thanks for the tips.

I tried with DivX WMA Audio, but VDub still couldn't open the file..

I tried with Avanti and I get an output avi file, but it can't be played with anything (classic WMP, etc). VDub sais that the file has no avi index or header!

It's so strange, cause it's such a simple thing that I want to do but still I can't ge around..

Is there any simpler, basic way to do it...?
