One year ago I provided a patch for mplayer which included support for quad-buffered stereo, enabling mplayer to display stereoscopic movies. In the meanwhile mplayer-1.0_rc4_p20101114 arrived in portage. As before with the original patch from Stuart Levy, my one does not work anymore due to some changes in mplayers gl2 driver. So I had to modify the patch again to work again with newer mplayer versions. You may download the updated patch from here:
The patch should work at least with nvidia quadro boards, probably with some others. It can be used with CRT and generic shutter glasses or HMDs like the Vusix VR920. Some stereoscopic sample movies for trying it out can be found on www.3d.wep.dk.
The Gentoo way
For Gentoo users I again modified the mplayer ebuild from portage to include the patch. The modified ebuild is available here:
The older ebuild and patch are still available on mygnu.de.
To use the ebuild it just copy it to /usr/local/portage/media-video/mplayer and copy the the patch to the “/usr/local/portage/media-video/mplayer/files” directory. You probably have to create these directories. Then run
ebuild /usr/local/portage/media-video/mplayer/mplayer-1.0_rc4_p20101114-r1.ebuild digest
Be sure to include the following line in your /etc/make.conf.
Then just re-emerge mplayer.
Now start mplayer with -vo gl2:stereo and enjoy the experience in the 3rd dimension again.
