Hi all,
I have the following question: I want to statically link my application
with a specific version off the ffmpeg libraries (20900) because we want
to use more than version of ffmpeg on the same machine. So, for this I
have done:
./configure --enable-static --enable-gpl --enable-libfaac
--enable-libfaad --enable-libx264 --enable-nonfree
make && make install
till now everything is just fine.
Now, I want to build link my application with ffmpeg:
gcc -Wall -g live_segmenter.c -o live_segmenter \
/usr/local/src/ffmpeg-20900/libavcodec/libavcodec.a
/usr/local/src/ffmpeg-20900/libavformat/libavformat.a
/usr/local/src/ffmpeg-20900/libavutil/libavutil.a \
/usr/local/src/ffmpeg-20900/libavdevice/libavdevice.a \
/usr/local/src/ffmpeg-20900/libswscale/libswscale.a \
/usr/local/src/ffmpeg-20900/libpostproc/libpostproc.a \
-lpthread -lbz2 -lm -lz -lfaac -lmp3lame -lx264 -lfaad
and I get the following output:

Do you have any idea what might cause this? I have observed that if I
add more libraries to the ffmpeg configure script (for example
--enable-libxvid) then I get even more undefined references to code
which has "xvid" in its name.
Thanks,
frc
