ERROR: cuvid requested, but not all dependencies are satisfied: ffnvcodec

If you think configure made a mistake, make sure you are using the latest

version from Git.  If the latest version fails, report the problem to the ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net. Include the log file "ffbuild/config.log" produced by configure as this will help solve the problem.

 

解决方法：安装NVIDIA headers

git clone https://git.videolan.org/git/ffmpeg/nv-codec-headers.gitmakesudo make install

然后重新configure：
