These support both software and hardware encoding.
Video encoders can take input in either of nv12 or yuv420p form
(some encoders support both, some support only either - in practice,
nv12 is the safer choice, especially among HW encoders).
Hardware-accelerated encoding is supported via D3D11, including hardware
Hardware-accelerated encoding requires D3D11, including hardware
scaling capabilities through the scale_d3d11 filter.
To list all available options for the MediaFoundation encoders, use:
@command{ffmpeg -h encoder=h264_mf}
@command{ffmpeg -h encoder=<encoder>} e.g. @command{ffmpeg -h encoder=h264_mf}
