Follow up

You reported motion version 3.2.11 but your log belongs to svn trunk. Motion doesn't support ALL version of ffmpeg only those stabled in linux distros and BSD , so trunk is not supported. Please use a ffmpeg version deployed by any distro or BSD.

I tried latest version of ffmpeg : svn-r17694 ( FFmpeg version SVN-r1769 )

with latest svn revision of motion trunk-r442 and got no problem :

LIBAVCODEC_BUILD 3412992 LIBAVFORMAT_BUILD 3415808

So probably you didn't compile on the rigth way ffmpeg as is explained in FAQ and other question support :

- ffmpeg :

./configure --enable-share ; make ; make install ; ldconfig

- motion :

./configure --with-ffmpeg=/usr/local ; make ; make install
