HW transcoding isn’t working smoothly with Nvidia GPU

I’m using 436.02 with HEVC hw decoding of 4k HDR streams.

For me, HW decoding only works when there’s a display plugged into the Quadro. In addition, I have to extend the display to the second GPU as well. To make it a bit less likely for random things to show up there, I set Quadro to 800x600 and configure the displays so that they only touch at a corner.

It’s a bit of a hack, but it’s the best I could find.

(This is on Windows, I haven’t tested Linux)

The new transcoder does seem to help somewhat, though I’m still noticing a bit of occasional buffering: it definitely seems less than before though.
