• The Mac-Forums Community Guidelines (linked at the top of every forum) are very clear, we respect US law and court precedence when it comes to legality of activity.

    Therefore to clarify:
    • You may not discuss breaking DVD or BluRay encryption, copying, or "ripping" commercial, copy-protected DVDs.
    • This includes DVDs or BluRays you own. Even if you own the DVD or BluRay, it is still technically illegal under the DMCA to break the encryption. While some may argue otherwise, until the law is rewritten or the US Supreme Court strikes it down, we will adhere to the current intent of the law.
    • You may discuss ripping or copying unprotected movies or homemade DVDs.
    • You may discuss ripping or copying tools in the context that they are used for legal purposes as outlined in this post.

Handbrake doesn't demux like what the OP appears to want, handbrake will transcode.

Demuxing is the process of taking a file that contains both video and audio and splitting it into separate files for video, audio, etc.

Now, if the OP mis-spoke and just wants to convert the file to a different container/possibly different codec, handbrake will work.

I honestly don't know of what to use to demux a flv.

Now you can transcode the flv to something like an mkv, then use mkvtools which contains mkvextract (although you have to use the command line) and extract the audio/video/etc.

There was a little app called BBDemux but not sure if it still works in modern versions of OSX. If the FLV were converted into say Quicktime or other formats, QuickTime Pro will let you rip the audio separate from the video, but the OP wants a free solution. I will check and see if BBDemux is still around.

Edit: Yes it is.

It's been a long time but I did way back need the music from a video I made and it did the trick. Not sure it will work with FLV though, but that can be converted.

I generally use Quicktime Pro with the Perian plugin so I can open the FLV directly in QT, then edit from there. :) But still, not free.

Yes, that does work for me also. Since like you said, the OP is looking for something free I did not mention it but it does work.
