此命令行工作正常：
$ ffmpeg -vsync 0 -hwaccel cuda -hwaccel_output_format cuda -i input_video.mkv -vf scale_cuda=720:404 -c:v hevc_nvenc -preset p7 -rc vbr -rc-lookahead 20 -b:v 2000k -bufsize 5M -maxrate 2000k -g 250 -an -sn output_video.mkv
但如果我添加-pix_fmt p010le或-pix_fmt yuv420p10le选项，我会收到错误：
$ ffmpeg -vsync 0 -hwaccel cuda -hwaccel_output_format cuda -i input_video.mkv -vf scale_cuda=720:404 -pix_fmt p010le -c:v hevc_nvenc -preset p7 -rc vbr -rc-lookahead 20 -b:v 2000k -bufsize 5M -maxrate 2000k -g 250 -an -sn output_video.mkv
Impossible to convert between the formats supported by the filter 'Parsed_scale_cuda_0' and the filter 'auto_scale_0'
