Topic: Add QSVenc Decoder option in SVP-Code

Seems like the video is being decoded by the CPU which is bottle-necking while encoding with hevc_nvenc. I think given the option to either decode with cuda or QSVenc should translate into way faster trans-coding speeds.

Re: Add QSVenc Decoder option in SVP-Code

the video is decoding using the whatever-is-set-in-mpv-conf decoder (which is "d3d11va-copy" by default)

however we'll release mpv built with QS and x265 encoders support, probably tomorrow
