Comment 4 for bug 438788

Thank you for reporting this to Ubuntu. We cannot sync this from Debian as is since it fails to build from source. I'm attaching the build failre, the relavent portion is here:
gcc -o ffmpeg2theora src/iso639.o src/ffmpeg2theora.o src/theorautils.o src/subtitles.o src/index.o src/avinfo.o -lvorbisenc -lvorbis -lm -ltheoraenc -ltheoradec -lavcodec -lavdevice -lavformat -lpostproc -lswscale -loggkate -lkate -logg
/usr/bin/ld: src/ffmpeg2theora.o: undefined reference to symbol 'av_free@@LIBAVUTIL_50'
/usr/bin/ld: note: 'av_free@@LIBAVUTIL_50' is defined in DSO /usr/lib64/libavutil.so.50 so try adding it to the linker command line
/usr/lib64/libavutil.so.50: could not read symbols: Invalid operation
