NVEnc Preview

[Dan64]

Answer from __AI__: Quick tested it with another 1920x1080 mp4, 4:2:0 video I have here and it worked, so ffmpeg's rawvideo loaded it ok, but your mp4 file did not work. I suspect that height mod might be a problem, it is 4 for 300, maybe mod 8 is needed for ffmpeg. Would resizing it to 304 help for example? Source video, not in vapoursynth.

I tried:

E:\VideoTest\TestSubs\NVEncC.exe --avhw --input "E:\VideoTest\TestSubs\TestSubs-1.mp4" -c raw --vpp-resize spline36 --output-res 720x304 --output-csp yuv420 --output-depth 8 --output-format raw --output - | E:\VideoTest\TestSubs\ffplay.exe -f rawvideo -pixel_format yuv420p -video_size 720x304 -i -

but the output image "is green"  maybe the problem is in ffplay version used.
I'm using:
