Well, the linker tries to link to the first library of the right name, with all the needed symbols. Because of the .1d, that library comes before the .52. At least thats what I think happens. You could try renaming the wrong libraries to some backup name, like libavcodec.backup.so.1d, which will keep the linker from using it, I hope. Then recompile your app, and see what happens.Oh, and the libavformat.so is a symlink to the latest version of libavformat, which in this case is libavformat.so.52
