3GP to AVI: how to at the best?

Asked by Uqbar

I need to convert 3GP video files to AVI.
I've tried mencoder (the one I know the best) with something like:
mencoder -oac pcm -ovc lavc ...
but the result is very poor.
Any int?

P.S.
This is exactly the opposite of another question (https://answers.launchpad.net/ubuntu/+question/19631).

Despite I have libamr installed.
As far as I understand, this is more or less the same approach as using mencoder, though.

Does your suggestion instead mean I need to install wine and then the Windows software in order to use the MediaConverter?

... and with the Windows version of theMedia Converter I get an error saying it cannot access the files.
I suspect is the problem with the \ and the / in the path.

1. mmc-src.zip is not compilable/runnable under Linux.
2. .deb file is for i386 while I run (as the majority of people) amd64 architecture
3. For the .tgz I didn't even think about doing manual install.

After having run:
sudo dpkg --force-architecture -i ./mmc_1.4.0_i386.deb
I got the package installed. After running it I got a decent conversion: GOOD.
I hope that in the future at least the shared libraries in that DEB file will be available also for amd64 architecture.

Grazie, Marcobra.
