Hi,
i have GPU GTX660Ti on debian buster 64bit, cpu intel core i7.
I have fresh install debian and install latest driver and cuda from
website nvidia, no repository of debian.
If convert file h264 with cpu it's ok, if use gpu i have error.
The video prova.ts is recorder from decoder sat.
The command used is:
ffmpeg -y -threads 8 -vsync 0 -hwaccel cuda -i prova.ts -r 24 -c:v
h264_nvenc -filter_complex yadif=parity=tff:deint=all,scale=1920:1080
-b:v 3M -c:a aac -b:a 192k -ar 48000 prova.mp4
This is output

Thanks.
Best regards.
Michele

Michele,
Use this:
ffmpeg -y -threads 1 -hwaccel cuda -i prova.ts -r 24 -c:v
h264_nvenc -filter_complex yadif_cuda,scale_cuda=1920:1080
-b:v 3M -c:a aac -b:a 192k -ar 48000 prova.mp4
Notes:
You're using nvdec hwaccel. Lower thread count for the decoder to 1, and
likewise use filters running on the GPU to prevent the need for hwdownload
filters.
Don't work, this is output
