I'm using a Yuan 4K60 capture card with the end goal of capturing the video
in a lossless format. I need it to be lossless as the clips will be used to
test hardware h264 encoders.

Only gets me x0.5 and the buffer overflows.
Is there a way of accelerating rawvideo decoding? Would using my colleagues
1080 make a difference? Thanks.

Hi James,
I get the same issue with this command:
ffmpeg -f dshow -video_size 3840x2160 -framerate 6/1001 -rtbufsize
21 -pixel_format bgr24 -i video="MZ0380 PCI, Analog 01 Capture" -c:v
h264_nvenc -preset lossless -f null -
Is there a way to accelerate the decoding of rawvideo?

I think I've figured it out. When I use nv12 or yuv420p as the input and output
pixel format, I get x1 performance. If I use bgr24/rgb24 as the input and
yuv444p as the output, I get around x0.3.
But even when I use bgr0 for the input and output, I get less than x1. Does
anyone know what exactl

What is the source of the video? From my quick googling, lens information and
other metadata is needed for fisheye to equirectangular conversion.

consider also libx264 "ultrafast" preset, GL!
