I've downloaded (legally) an MP4 movie fro archive.org. I want to play it on my new Archos Gmini 400 which plays

"MPEG-4 SP with MP3 or ADPCM stereo sound, up to 640x400 @ 30 f/s, AVI file format. Reads XviD and DivX®** 4.0 & 5.0. Play Music Video in MPEG-4"

I'm told the reason it doesn't work is it likely has AAC audio. Is there a tool I can use to strip out and re-encode just the audio. I'm a newbie at this stuff but not an idiot ;-)

Thanks in advance
Bill

Think it was me that said that. If so I also said that the mp4 container is most likely an issue.

mencoder.exe -ovc copy -oac mp3lame input.mp4 -o output.AVI would I guess work. You would I think end up with mp4v for a FourCC though which may not work. Not sure if -FourCC DIVX works with -ovc copy.

Otherwise you could Demux the streams using say mp4box, re-encode the audio, then remux.

Would be much better if all these players just supported mp4 (official MPEG-4 container) instead of AVI, asf, etc.

You did say the container would be an issue.

Demuxing, converting the audio and remuxing sounds like the ticket

Thanks
