 Summary of the bug:

 I'm trying to combine the OpenCL version of the nlmeans filter with the
 nvenc HEVC encoder without copying frames to system memory based on
 @philipl's suggestion from [https://trac.ffmpeg.org/ticket/8512#comment:4
 #8512] but I'm getting errors:

 {{{
 [Parsed_hwupload_0 @ 000001e080a88980] Query format failed for
 'Parsed_hwupload_0': Function not implemented
 Error reinitializing filters!
 Failed to inject frame into filter network: Function not implemented
 Error while processing the decoded data for stream #0:1
 }}}

 How to reproduce:
 {{{
 ffmpeg -hwaccel nvdec -hwaccel_output_format cuda -i in.mkv
 -init_hw_device cuda -filter_hw_device cuda0 -filter:v
 "hwupload=derive_device=opencl,nlmeans_opencl,hwupload=derive_device=cuda"
 -c:v hevc_nvenc -preset p7 -rc vbr -cq 24 -c:a copy out.mp4
