patch, works fine for me

Please make x11-libs/libXvMC optional: xvmc does not support h264 and vp8 and is useless for me. I consider xvmc obsolete and do not want to have anything related to it in my systems. Attached patch works fine for me: KDE session restarts, watching video with mplayer2 works.

P.S. Seems there is missing sys-fs/udev RDEPEND and possibly udev USE.
Also what about adding debug, dga, kms-only, xaa USE flags? Not sure about "userptr" and "async-swap" options.

Seems reasonable. I don't want to expose all those other options though.

On it.

[Comment 3 Rémi Cardona (RETIRED) 2012-09-11 21:18:52 UTC]

Fixed in portage and x11 overlay.

FTR, XvMC support is really small, and though I know it's only useful for MPEG-2, we forced it in for everyone since its deps were really limited. The USE flag is indeed a nice improvement.

I want to thank you for a very nice and clean patch, it makes our job a whole lot easier. :)

Cheers
