How to extract Audio from Rmvb?

[iwod]

It is an "Cook" audio stream. Is there any way i could extract it?

[space1999]

Have you already tried ffmpeg? :confused:

ffmpeg -i input.rm -acodec copy output.aac

[iwod]

Doesn't work

[roozhou]

ffmpeg -i input.rm -vn -acodec copy output.aac

[iwod]

I am sorry it seems i was getting wrong info ( ?? ) It is not AAC but cook audio file. How do convert it out ?

[roozhou]

Try mmg from mkvtoolnix.

ffmpeg can decompress Cook Audio

(or at least the command-line "ffmpeg -codecs" says so).

@Midzuki
iwod said "extract" not "decode". Transcoding is always easier than remuxing.
