[FFmpeg-user] missing h264_cuvid

I think the problem is more on the decoder you are using.
Apparently your ffmpeg is compiled to support cuvid.... but if your stream is dvb-s mpeg2 maybe you should use this decoder:

V..... mpeg2_cuvid          Nvidia CUVID MPEG2VIDEO decoder (codec mpeg2video)

Hello.
I'm not sure but you have to compile at least with --enable-cuda --enable-cuvid --enable-nvenc.
Can you try compiling with those enabled?

Moreover i don't know if you want/need --enable-opencl
