This comes from compiling (and then failing to link) ffmpeg's h264_vda which
should have been disabled by passing --disable-hwaccels to ffmpeg in the first
place.
Simple solution is to explicitly disable using VDA (VideoDecoderAcceleration)
in the ffmpeg config stage. Note that VDA is going to be deprecated in 10.11
anyway. See attached patch.
