Here (debian sid) it doesn't work becase avformart.h includes in this way:


 40 #include "libavcodec/avcodec.h"


and the error:

In file included from /home/kde-devel/src/kdenlive/KDE4/src/renderer.cpp:28:
/usr/include/ffmpeg/libavformat/avformat.h:40:32: error:
libavcodec/avcodec.h: No such file or directory

Maybe(in my case) /usr/include/ffmpeg should be  in include path too?
