I’d like to use cuda gpu as below. But ffmpeg keep saying that
“Impossible to convert between the formats supported by the filter ‘Parsed_hwupload_cuda_0’ and the filter ‘auto_scale_2’
[fc#0 @ 0000018ff3ff4e80] Error reinitializing filters!

How to fix the issue?

I have change options, but no luck.
