I need to convert an mp4 video to wav.

Is there a way to do that in Fedora 13?

Thank you

Do you mean you just want to pull out the sound?  ffmpeg will do it,
something like

   ffmpeg -i file.mp4 -o file.wav

There are a zillion options, so be sure to 'man ffmpeg'.

Good eyes!

I hate it when I do that - make a typo and *not* see it!

That did the trick!

Thank you

Maybe because you actually want ...wmv, not ...mwv?

Steven,

Thank you very much for taking the time to reply.

I actually goofed - I meant wmv not wav.

I looked at 'man ffmpeg'

and am failing to get the correct ffmpeg to convert from mp4 to wmv,

I tried
$ ffmpeg -i ./LegalShield-and-IDT-Overview.mp4 LegalShield-and-IDT-Overview.mwv

I'm guessing I'm missing an encoder.
