If the camera has not already been activated, a one time spin up may incur some auto exposure as well as initial streaming frame delays. The camera should be considered a global resource accessible for shared consumption but not exclusive to any caller. The camera may go inactive due to lack of active consumers or headset idleness.

VRTrackedCamera_GetVideoStreamFrameBuffer back to summary

public static int VRTrackedCamera_GetVideoStreamFrameBuffer(long hTrackedCamera, int eFrameType, ByteBuffer pFrameBuffer, CameraVideoStreamFrameHeader pFrameHeader)

Copies the image frame into a caller's provided buffer. The image data is currently provided as RGBA data, 4 bytes per pixel. A caller can provide null for the framebuffer or frameheader if not desired. Requesting the frame header first, followed by the frame buffer allows the caller to determine if the frame as advanced per the frame header sequence. If there is no frame available yet, due to initial camera spinup or re-activation, the error will be VR#EVRTrackedCameraError_VRTrackedCameraError_NoFrameAvailable. Ideally a caller should be polling at ~16ms intervals.

Parameters

eFrameType:int

one of:

VR#EVRTrackedCameraFrameType_VRTrackedCameraFrameType_Distorted

VR#EVRTrackedCameraFrameType_VRTrackedCameraFrameType_Undistorted

VR#EVRTrackedCameraFrameType_VRTrackedCameraFrameType_MaximumUndistorted

VRTrackedCamera_GetVideoStreamTextureD3D11 back to summary

public static int VRTrackedCamera_GetVideoStreamTextureD3D11(long hTrackedCamera, int eFrameType, long pD3D11DeviceOrResource, PointerBuffer ppD3D11ShaderResourceView, CameraVideoStreamFrameHeader pFrameHeader, int nFrameHeaderSize)

Access a shared D3D11 texture for the specified tracked camera stream.

The camera frame type VR#EVRTrackedCameraFrameType_VRTrackedCameraFrameType_Undistorted is not supported directly as a shared texture. It is an interior subregion of the shared texture VR#EVRTrackedCameraFrameType_VRTrackedCameraFrameType_MaximumUndistorted. Instead, use GetVideoStreamTextureSize with VRTrackedCameraFrameType_Undistorted to determine the proper interior subregion bounds along with GetVideoStreamTextureD3D11() with VRTrackedCameraFrameType_MaximumUndistorted to provide the texture. The VRTrackedCameraFrameType_MaximumUndistorted will yield an image where the invalid regions are decoded by the alpha channel having a zero component. The valid regions all have a non-zero alpha component. The subregion as described by VRTrackedCameraFrameType_Undistorted guarantees a rectangle where all pixels are valid.
