I have a Fujifilm Finepix Real 3D camera which takes pictures as MPO files (as does the iPhone 3D Photo app). The Pigusus VR Media Player app for the Oculus will view these photos in the native MPO format without having to convert them to side-by-side images, and is very convenient for going through a file of 3D MPO images and viewing them as you would work through a file of 2D images on a PC. It will also view any side-by-side images you may have. The Pigusus app is not free, but it is inexpensive (currently under $10).
The Pigusus app will not directly play the 3D AVI Video files created by the Fujifilm camera, however, there is a workaround. The 3D AVI files can be edited and exported as side-by-side video files with the free StereoMovie Maker app for PC (stvmkre), and these side-by-side files can be viewed on Pigusus.
Note that there is also a free StereoPhoto Maker (stphmkre) application for PC by the same company that can be used to edit your 3D photos or create 3D photos from individual side-by-side photos.
It would be nice if Oculus had native support for MPOs, but this appears not to be the case.
Hiya, little bit late to the party but I used to do this with a program called Panorama Stitcher on the Mac. I could then send back to my phone and upload to google maps for viewing on the Wander app.
I could also upload to Facebook and also transfer via USB straight to my oculus to view it there in a high quality..
