Re: [gentoo-user] libav and ffmpeg on the same computer issue once again

[Gregory Woodbury]

I had a similar problem with some packages wanting virtual/ffmpeg  and
it wouldn't take the -libav USE flag without adding a keyword for
~amd64 on the virtual.
(yes, I am going the opposite way from you, but the cause seem the
same -- various USE flags are not yet adjusted in the stable
branches.)

Perhaps we need to request "stabilization" for some of the newer
packages to solve this.
