The includes here on my system are:
#include <ffmpeg/libavformat/avformat.h>
#include <libavcodec/avcodec.h>
#include <ffmpeg/libswscale/swscale.h>

and not:
#include <libavformat/avformat.h>
#include <libavcodec/avcodec.h>
#include <libswscale/swscale.h>

This worked, so erhaps the builddepends could be updated to include >
