Apps can expose spectator, drone, or avatar views as Camera2 devices. Understand GPU lifecycle, formats and cost.
Direct answer
Meta VR OS Native SDK's Virtual Camera Publisher allows an XR application to publish virtual cameras visible to Android consumers via the Camera2 API. You can provide spectator, drone or avatar views, with up to three cameras and rates of up to 60 frames per second, using RGBA or YUV formats. The application must render only when a consumer opens the camera, synchronize frames and handle termination correctly to avoid idle GPU expenditure. The feature requires specific permission and validation on the device; The documentation states that testing via Link is not supported.
The virtual camera becomes a system contract
The consumer sees a Camera2 device. Identity, capacity, resolution, and state need to remain stable throughout the session.
Rendering must follow demand
Producing frames without a consumer wastes GPU and battery. Open resources at effective start and release everything after closing or error.
Format changes cost and integration
RGBA favors direct rendering; YUV can serve video and broadcast. Conversion, copying and synchronization should be part of the performance budget.
Multiple views expand production
Viewer, drone and avatar can feed recording, remote support or transmission, as long as privacy and consent are addressed.
Nexus Reading
Set resolution and fps by use case, measure GPU and latency, test repeated opening and closing, and maintain fallback when the camera is unavailable.
