There is a new Couch Games Software on Google+ (http://goo.gl/1WQNDl): make sure to subscribe if you are interested in news about this app!WARNING: this is a beta version, and although it seem to work fine on a lot of devices, it sports such astonishing features as:
• sub-par graphics and plain CSS contents• clumsy controls• limited features• embarrassing User Interface• limited movie formats compatibility----
Theater for Cardboard allows you to enjoy your own 2D and 3D movies in a virtual cinema, for free (it also supports panoramic 360° and 180° movies)!
Do you have your Google Cardboard ready (or, why not, a better headset, like the Homido VR)? Good! Just upload the movies on your phone (or open them directly from a browser or a 3th party application!), load them with this app, and enjoy!
Theater for Cardboard supports SBS, Over/Under and Red-Cyan anaglyph formats, as well as plain 2D movies in all formats originally supported by your phone (go for the .mp4 files for a sure hit: your mileage might vary with other formats), and can be used both on devices with a cardboard trigger, or with the ones without one (with a keyboard or a classic focus control scheme).
.srt subtitles encoded in UTF-8 are also supported, and can be selected manually, or automatically detected if they are named like the video.
Make yourself at home: check the "Options" menu and configure the theater to your liking!
The movie represented on the virtual screen ("Elephants Dream" (c) copyright 2006, Blender Foundation / Netherlands Media Art Institute / www.elephantsdream.org), can be freely downloaded in both SBS and over/under version at the URL: https://orange.blender.org/blog/elephants-dream-in-stereoscopic-3d
