It is likely that the problem comes from using a version of the ffmpeg library different from what gegl expects -- possibly due to having multiple versions of the library on your system. If you don't want to spend time figuring out how to solve that, the simplest solution, I believe, is to rebuild gegl using the --without-libavformat configure option.
