In 49e3b03885bd0c00fcd9b64c2f4d6b77ad68b62a we turned on SW encoders / decoders
on account of some devices having broken HW *encoders* and also our desire for
using simulcast.
Well, the astute reader may have noticed that only *encoding* was mentioned.
Indeed, we should be able to keep using the HW decoder just fine.
