Disable hardware decoders due to broken failure modes

Even though we do not ship the necessary software to make these
work out of the box, libavcodec does not correctly disable these
to clients when no software implementation exists.

Additionally, the codec preferences seem to be wonky and need to
be tweaked before we turn these back on.
