As far as I know, x11-libs/libXvMC does not work with the binary nvidia drivers -- and is, in fact, wholly unnecessary here -- the only file that could possibly be useful is /usr/include/X11/extensions/XvMClib.h x11-drivers/nvidia-drivers-1.0.8776 installs /usr/lib64/libXvMCNVIDIA.so whether xvmc is in USE or not -- and this is the library that should be used. media-video/mplayer-1.0_pre8 follows the nvidia USE flag, and links against that, giving me a flawlessly working mplayer -- but media-video/mplayer-1.0_rc1 ignores that flag and depends on libXvMC, making it entirely useless for XvMC playback on nvidia devices. It's possible that I'm entirely wrong, and there's a new way of doing XvMC, or there's some sort of trick with eselect -- though I did check eselect modules. If this is the case, please update http://www.gentoo.org/doc/en/nvidia-guide.xml to reflect the right way of getting XvMC working. Reproducible: Always Steps to Reproduce: 1. USE="xvmc nvidia" emerge mplayer 2. mplayer -vo xvmc -vc ffmpeg12mc /some/file.vob 3. notice that somebody broke mplayer's XvMC support Expected Results: Either: mplayer should honor USE="nvidia" like it has in the past mplayer probably should not depend on x11-libs/libXvMC if USE="xvmc nvidia" OR: documentation should be updated to explain how this is supposed to work obligatory "emerge --info": elite ~ #

Seems like media-libs/xine-lib is similarly changed. Nothing in either ebuild, or in the changelogs, suggests that XvMC support is any different... Am I reading this wrong? Is x11-libs/libXvMC the "wrapper library", that magically finds XvMCNVIDIA? Aha. Finally found it. /etc/X11/XvMCConfig, which exists on my system, was set to libXVMCNVIDIA.so -- needed to be libXvMCNVIDIA.so. Yes, it was the v in XvMC. Sometimes I hate Unix case-sensitivity. Anyway, changing "product" to "documentation" -- would be nice if there was some warning, somewhere -- or better, if x11-libs/libXvMC would notice video card USE flags and set its config file appropriately, when installed.
What installed /etc/X11/XvMCConfig? Has nothing to do with documentation...
(In reply to comment #2) > What installed /etc/X11/XvMCConfig? Has nothing to do with documentation... Has everything to do with documentation. But I just checked: elite ~ # equery b /etc/X11/XvMCConfig [ Searching for file(s) /etc/X11/XvMCConfig in *... ] elite ~ # Apparently, I put XvMCConfig there earlier, and forgot about it. Maybe the library itself changed case, or maybe XvMCConfig never worked. Or maybe it was a postinstall script. Whatever the case, how is this not a documentation issue? Have you read the website I sent you to? This is a config file -- it should be documented like every other config file. Or, put another way: elite ~ # man xorg.conf Formatting page, please wait... elite ~ # man XvMCConfig No manual entry for XvMCConfig elite ~ # The bug in documentation is that there is no documentation, even though it's a mind-numbingly simple file (or setting). It should be there in the nVidia guide, at the very least -- and if the file is modified via USE flags, it should say so. I'll gladly write the documentation if you like, it would be less than a page, but surely there should be something, right?
Just FYI: without that file you only get XvMCWrapper: Could not open config file "/etc/X11/XvMCConfig". So I actually think this is a bug in x11-libs/libXvMC which IMO preferably should at least try to create a somewhat useful default configuration.

Anyone want to write such a patch? :)
*** Bug 173901 has been marked as a duplicate of this bug. ***
try to give app-admin/eselect-xvmc a whirl. I just added it.
Doug's eselect-xvmc should indeed make everything simpler. Please don't hesitate to open a new bug if eselect-xvmc gives you any trouble. Thanks
