    128 FFmpeg now uses its own slightly modified runtime-loader for nvidias CUDA/nvenc/nvdec related libraries. 
    129 If you get an error from configure complaining about missing ffnvcodec, this is what you need: http://git.videolan.org/?p=ffmpeg/nv-codec-headers.git;a=summary 
    130  
    131 It has a working Makefile with an install target: {{{make install PREFIX=/usr}}} 
    132 FFmpeg will look for its pkg-config file, called ffnvcodec.pc. Make sure it is in your PKG_CONFIG_PATH.

    148 The note about ffnvcodec from nvenc applies for cuvid/nvdec as well. 
    149  
    150 CUVID, which is also called nvdec by NVIDIA now, can be used for decoding on Windows and Linux. 
    151 In combination with nvenc it offers full hardware transcoding.
