The ability to create 360º videos is as easy as shooting regular video with cameras such as the Ricoh Theta. Online social media sites, such as YouTube, are beginning to provide the ability to load and share these videos online.
These abilities are still in their infancy, and for example, YouTube requires that the video be update with specific metadata that identifies the video as a equirectangular 360º video format for this to work. Also, playback is limited to only desktop computers running Google Chrome or Android devices.
Update – It appears that the Firefox browser works now too.
