[FFmpeg-user] missing h264_cuvid

[Daniel]

Hello everyone,

I am trying to decode stream using h264_cuvid decoder but unfortunately 
i get the following error : "Unrecognized hwaccel: h264_cuvid.
Supported hwaccels: vdpau vaapi cuvid " same time if i request 
"/usr/local/bin/ffmpeg -decoders |grep -i h264 " i get this result:

  V..... h264_cuvid           Nvidia CUVID H264 decoder (codec h264)

can you tell me if ffmpeg is missing h264_cuvid decoder or it could be 
something else.The stream i am trying to decode is dvb-s mpeg2 that's 
why i doubt about the decoder i have to use(i would like to use hwaccel 
decoder).

Thank you
