Created attachment 534322 [details] build.log I get the following error trying to emerge ffmpeg-9999: (ERROR: ffnvcodec requested but not found 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.) It has been like this for a couple weeks or so. I think they moved something around upstream.
Same problem here.
I also experienced the same issue. In my case, per the ffbuild/config.log, it is a result of an outdated nv-codec-headers. Today's ffmpeg-9999 wants >=8.1.24.2, but the only one in gentoo's tree is 8.1.24.1. I think we need a nv-codec-headers-9999.ebuild to go with ffmpeg-9999 now.
