Did you try with ccache disabled, yet?
(In reply to comment #4) > Did you try with ccache disabled, yet? ^ reopen after testing, thanks
do you have libav installed? It look like this is some missing include...
Provide output of `emerge -pv --nodeps virtual/ffmpeg media-video/libav media-video/ffmpeg` Try upgrading ffmpeg (or libav) Try current alsa-plugins-1.0.27 Let us know which versions caused the failure Unlikely this is any of a problem with current versions in the portage
