Comment (by oromit):
./ffmpeg -r 50 -c:v mpeg2_cuvid -deint adaptive -i ~/00001.ts -sn -an -qp
22 -c:v h264_nvenc -y out.mkv
Works fine for me on release/3.4, release/4.0 and master.
Note the -r 50 as input option, for the file which is originally 25 fps.
You need to manually specify that, as ffmpeg.c is not up to the challenge
of changing the fps from inside of a decoder.
