Apparently, there is an application that states it can convert videos to the VR format. I've checked its page and it appears that it does what it says, but if I were you I would take it with a grain of salt.
Convert a video to a new technology isn't just a simple operation like add video, convert, save, play.
You can give it a try using the following link: http://www.ifunsoft.com/ifunvideoconverter.php
Note: Make sure your antivirus is turned on in case the software is bundled with other apps.
