Hi,

I try to extract sound only from an DVD video with Mencoder. I use DevedieGUI.

As I only want the audio file I select "Audio only" (frameno) under video and "Uncompress" (raw PCM) under audio which then copies me a file (the file should be rawPCM but I dont know as I'm not able to play it) e. g. to RAM.

I'd like to convert this file then to e. g. aiff or wave format?

Does anybody have an idea how to do this?

Thanks for your help.

Regards

Christoph

IIRC play16 is able to convert raw sound data ...

MEncoder doesn't actually support outputting raw audio, when you select frameno it will create an AVI containing just the audio stream...

To do what you want to do you should actually use MPlayer, and instead of using AHI to play audio you can make it output raw pcm or wavs with "-ao pcm" (check the docs), to avoid unnecessarily playing/decoding the video as well you can use "-novideo".

Does MorphOS version of mplayer support -dumpaudio? I can't test it myself, as my Radeon broke

Sure, but -dumpaudio will dump the audio-stream as stored on the DVD, ie, if it's AC3 you will get an AC3 stream, this isn't what he wants...

Hi all,

thanks for your feed-back. It seems that I wasnt clear enough. What I'd like to do is to extract audio from an DVD as e. g. an aiff or wave file which seems not to be possible.

What I was able to do though is to extract raw pcm which then I could encode to an mp3 after extraction, but I was not able to transform the raw pcm file to an aiff or wave.

So I wanted to know how to transform the raw pcm file to aiff or wave.

Thanks for your help.

mplayer .. -dumpaudio -dumpfilename ...ac3
ac3dec .. MODE aiff ..

You may lookup the correct parameters yourself.

thank you.

What do you mean? MPlayer does just that, like I told you, using "-ao pcm:file=foo.wav"...

@ CISC

thanks very much for your help, it's working fine when used as you told me.

Thanks again.
