Hello,

When I try to use any gegl operation eg - load on running the file i get the
error -
Message: Module '/usr/local/lib/gegl-0.1/ff-load.so' load error: /usr/local/lib/gegl-0.1/ff-load.so: undefined symbol: avcodec_decode_video2

can anyone help??

just guessing, but when you ran autogen.sh to configure gegl, did you have this output.

checking for AVFORMAT... yes checking libavformat/avformat.h usability... yes checking libavformat/avformat.h presence... yes checking for libavformat/avformat.h... yes checking linux/videodev.h usability... yes checking linux/videodev.h presence... yes checking for linux/videodev.h... yes

So do you have avformat.h

Do you have videodev.h

As I said, just a guess

I searched for avformat.h and found it on my system -

/usr/include/libavformat/avformat.h

what actually is this error from??

Do you have videodev.h

Again, I am only guessing but avcodec_decode_video2 is a variable or function for decoding video.

What system are you using. just install anything that looks like avformat, libavcodec, ffmpeg, anything to do with video then recompile gegl and try again.

you are simply missing something.

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.
