Remove dependency on libavformat
...
When searching for ffmpeg or libav we currently look for libavformat and search for a specific version. We have no use for the libavformat library as we only use libavcodec and (indirectly) libavutil. The version numbering in libavformat is also completely irrelevant for our use.
With this commit, we will look for libavcodec instead.
