Virtual reality video scope of support

Radiant Media Player is committed to supporting the latest innovation in the online video world. We are pleased to announce support for virtual reality video through head-mounted display with Radiant Media Player 5.5.

Supported input format

Radiant Media Player supports playback for side by side videos, used in the context of a VR headset, through HLS, DASH & progressive download. 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:

Supported environments

In order to provide side by side videos, used in the context of a VR headset, Radiant Media Player makes use of the WebXR Device API. We use three.js as VR framework (this framework is publicly available under MIT license). As of version 5.5 we support the Oculus platform.

We support the Oculus browser, Samsung Internet VR and Firefox Reality.

Example of supported devices: Oculus Go, Oculus Quest & Samsung Gear VR
