Comment (by malakudi):

 Will try to do it as soon as possible. FYI, if there is a cuda filter in
 the command (scale_npp, yadif_cuda etc), then there is no issue again.

 For example, this works:

 {{{
 ./ffmpeg-git -hwaccel nvdec -hwaccel_output_format cuda -f mpegts -i
 input_sd_interlaced_50i_mbaff.ts -vf scale_npp=w=544 -vcodec h264_nvenc
 -refs 4 -bf 3 -c:a copy -f mpegts -y /dev/null
