Virtual reality video documentation

Virtual reality video scope of support

Radiant Media Player is committed to supporting the latest innovation in the online video world. As part of this commitment we support VR video (viewable through a head-mounted display) and 360 video in our player.

Supported input format

Radiant Media Player supports playback for VR 180 video (also known as 180 3D video or side by side videos) viewed in a VR headset, through HLS, DASH & progressive download. VR 180 is a video file containing 2 channels of video for the left and right eye, but for only the front facing 180 degree field of view. A more detailed explanation about VR and 360 video formats can be found here.

This works for live or on-demand video content. Given the nature of side by side videos (which can easily scale up to 4K resolution) using an adaptive bitrate streaming like HLS or DASH technology is generally recommended. Example of VR-ready side-by-side video compatible with Radiant Media Player:
