BUG: multiple definition of `file_protocol'

I used the latest svn from ffmpeg, configured it with "./configure" (and make, make install) and got the daily snap of motion (20071128-051001). I then configured motion with "./configure --with-ffmpeg=/usr/local". I got a TON of "undefined reference to" until I added "-lavutil" in the LIB section of the Makefile. The only thing it complains about now is file_protocol. 3.2.9 has this problem but also 20071128-051001.

How did you compile ffmpeg ?

I tried to reproduce in debian etch with ffmpeg svn -r11130 and no errors.

btw if you install ffmpeg in /usr/local don't need to specify --with-ffmpeg=/usr/local

* ffmpeg

./configure --enable-shared ; make ; make install

* motion
