Topic: Does SVP require copy-back decoding? (re: RIFE, etc)

I'm using MPV (and MPC-HC/DirectShow) but I have a question...

Does SVP require copy-back decoding with RIFE (or SVP interpolation) ?

I'm wondering if we can use non-copyback because all of the processing is happening on the GPU and the avoid the frame copying back to system memory and back again to the GPU?

Unless you have a very weak GPU then you are not loosing anything by using copy-back. Plus I'm not sure that  "all" of the processing is done in GPU. I use software decoding by default anyway. There was some confusion recently but it looks like you can get away with not using copy-back and mpv (or I think actually ffmpeg) will do it for you anyway. So again, I'm not sure you are gaining anything because it looks like some sort of copy-back process still takes place. Hopefully a dev will have a more definitive answer.
