DXVA2/D3D11VA work perfectly fine, on Windows i see no huge reason to
use NVDEC (and the same can probably be said for whatever AMD
solution) - and in fact from a user (and developer) perspective its
much nicer to just use the same hwaccel on all hardware. But Linux is
another matter. I don't know how well AMD works with VAAPI or VDPAU
(if at all), but at least for NVIDIA VDPAU has its issues and VAAPI is
not supported at all (except with a VAAPI VDPAU adapter, which  has
the same issues, obviously)

Until you guys actually provide Linux support, adding a HWAccel might
not be that advantageous for the user-base.
