Trying to deinterlace with Bob NVEnc; job crashes

[Selur]

Any idea why:

ffmpeg -y -loglevel fatal -noautorotate -nostdin -threads 8 -i "G:\TestClips&Co\files\test.avi" -map 0:0 -an -sn -c:v mpeg4_cuvid -deint 1 -vf zscale=rangein=tv:range=tv -pix_fmt yuv420p10le -strict -1 -vsync 0 -f yuv4mpegpipe - | ...

would abort with:

Unknown encoder 'mpeg4_cuvid'

mpeg4_cuvid is listed when using "ffmpeg -decoders".

Same with h264_cuvid:

ffmpeg -y -noautorotate -nostdin -threads 8 -r 30000/1001 -analyzeduration 24M -probesize 24M -i "G:\TestClips&Co\files\MPEG-4 H.264\00001.MTS" -map 0:0 -an -sn -c:v h264_cuvid -deint 1 -vf zscale=rangein=tv:range=tv -pix_fmt yuv420p10le -strict -1 -vsync 0 -f yuv4mpegpipe - |  ...

gives:

Unknown encoder 'h264_cuvid'

Are the cuvid decoders not usable with yuv4mpegpipe-pipe output?
