[FFmpeg-user] How do I accelerate fisheye to hequirect conversion with cuda?

[Alexander Winnig]

This is my command

ffmpeg -y -i in.mp4 -vf 
v360=input=sg:ih_fov=118.2:iv_fov=69.5:output=hequirect:w=2924:h=2924 
-b:v 102400k -bufsize 5000k -c:a copy out.mp4

|ffmpeg -y -hwaccel cuda -hwaccel_output_format cuda -i in.mp4 -vf 
v360=input=sg:ih_fov=118.2:iv_fov=69.5:output=hequirect:w=2924:h=2924 
-c:v h264_nvenc -preset slow -b:v 102400k -bufsize 5000k -c:a copy out.mp4|
