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
