[FFmpeg-user] ffmpeg cuvid not transcoding properly

[Andy]

It seems like again I hit the wall. While one mpeg2 source works with
the mpeg2_cuvid option, the other gives me troubles.

ffmpeg -threads 1 -vsync 1 -hwaccel cuvid -c:v mpeg2_cuvid -deint 1
-drop_second_field 1 -i 'http://0.0.0.0:46007' -c:v h264_nvenc -vb
