Recently, the popular video watching application for virtual reality headsets, Bigscreen , released a videoplayer update that will allow you to play your own video files. Offering the opportunity to watch movies for all compatible virtual reality headsets such as Oculus Quest, Oculus Rift, Oculus Go, HTC Vive, Valve Index, all SteamVR headsets, and Windows Mixed Reality, Bigscreen won great acclaim from users with this update.

If your friend also has the same file, it synchronizes the playback time of the file, making it compatible for you to watch together. However, keep in mind that it doesn’t broadcast to others by streaming your files online. The player, which can play 2D (2-dimensional) and 3D (3-dimensional) videos with multi-monitor support on Windows, does not yet support 180/360 degree videos.
