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.
