About CastXR SDK
CastXR SDK streams your Unity XR application from a standalone headset to a Windows PC in
real time — typically under 100 ms on a local network, peer-to-peer over WebRTC, with no
capture card and no cloud service.
NO CODE TO WRITE
Import the package and run two menu items. The setup wizard installs the WebRTC dependency,
creates a config asset and adds a configured object to your open scene. A second wizard
verifies the Android and OpenXR settings streaming needs and fixes them one click at a time.
Then build your APK exactly as you already do.
There are no SDK calls to make, no prefabs to wire and no callbacks to implement.
WHAT YOU GET
- Real-time video and audio — hardware H.264 on the headset, Opus audio, carried by WebRTC
- Zero-configuration discovery — a headset on the same Wi-Fi appears on the PC by itself.
No IP addresses, no pairing codes, no router changes
- Live quality control — change resolution, frame rate and bitrate per headset while it
streams, without restarting
- Self-healing sessions — the stream recovers on its own when a headset sleeps, loses
tracking or leaves the play boundary
- Many headsets at once — watch a room full of headsets side by side on one PC
- Full C# source — read every line before you ship it
FREE TO EMBED
No activation check, no runtime fee, no phone-home. Embed it in commercial projects at no
cost. The SDK contains no licence check of any kind.
YOU ALSO NEED THE FREE RECEIVER
This SDK is the sender. The video has to arrive somewhere, so you need CastXR Viewer for
Windows on the PC — free on the Microsoft Store, signed and distributed by Microsoft.
Free forever for one headset at up to 720p. No account, no key, no time limit — enough to
develop, test and ship with. Paid tiers lift the limits; nothing in this SDK is time-limited.
WHAT IT DOES NOT DO
CastXR only streams applications built with this SDK — software you or your team built. It
cannot capture other applications on the headset, or the system menus. That is a design
decision, not a missing feature.
REQUIREMENTS
- Unity 6000.0 or newer
- com.unity.webrtc 3.0.0 or newer (the setup wizard installs it)
- A standalone Android XR headset — Android build target, IL2CPP, ARM64, Vulkan
- Windows 10 1809 or newer for the receiver
Note: com.unity.webrtc 3.0.0-pre.7 and -pre.8 silently transmit no video on Android with
Vulkan. Use 3.0.0 or newer. The setup wizard checks this for you.
SUPPORT
Manual, troubleshooting and contact details ship with the package.
