I'm trying to install FFMPEG with MS-GSM support, and I was reading a
thread on this list dealing with "[PATCH] MS-GSM support: draft for
review" (started by Michel Bardiaux on Nov 6).

As I understood, I must download the revision 6917, right?
svn checkout --revision 6917 svn://svn.mplayerhq.hu/ffmpeg/trunk ffmpeg

And I installed the library (on Linux Fedora Core):
[]# ./configure --enable-gpl --enable-mp3lame --enable-shared
--prefix=/usr --enable-libgsm
[]# make
[]# make install

But I get an error message when trying to convert an AVI video to FLV:
[]# ffmpeg -i video.avi -ar 22050 -ab 32 -f flv -s 320x240 video.flv

As I'm concerned, this means my FFMPEG doesn't support the 0x0031
(MS-GSM) codec. What am I doing wrong? Thank you very much.
