Arch is offering ffmpeg in the main repositories while the developer is developing against libav. Installing libav from the AUR instead of ffmpeg makes this unpaper package work again. The developer just merged a patch to make it compatible with ffmpeg *and* libav. So the next release, 6.1 published as of today, should work with both libavcodec providers (until they get incompatible again ;-) ).
