stereoscopic mplayer

Experimenting with my VR920 3D stereo glasses I found a patch to enable stereoscopic support in mplayer (thanks to Stuart Levy). With this patch I can now watch 3D movies on my eyewear under linux. Let me tell you, it’s a really cool experience.

The patch should work at least with nvidia quadro boards, probably with some others. It can also be used with CRT and generic shutter glasses. You can download the patch from here:


Some stereoscopic sample movies for trying it out can be found on

For Gentoo users I modified the mplayer ebuild to include the patch. Download from here:


To use it just copy the mplayer subtree from the portage tree to /usr/local/portage/media-video/mplayer and remove the ebuilds. Copy the new ebuild to that directory and the patch to the “files” directory. Then run

ebuild /usr/local/portage/media-video/mplayer/mplayer-1.0_rc2_p28058-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 a new experience in the 3rd dimension.

Addon: Updated modified ebuild for the new version in portage tree:
