OpenVR SDK 1.0.17
IVRProperties:
- Prop_CameraStreamFormat_Int32 - value from the openvr_driver.h ECameraVideoStreamFormat indicating the expected delivery format of the device
- TrackedProp_IPCReadFailure
IVRTrackedCamera:
- CameraVideoStreamFrameHeader_t:: ulFrameExposureTime - additional field which carries the time in absolute system ticks of when the frame exposure happened, and the time of the frames pose.
- CVS_FORMAT_YUYV16 - new opener_driver.h ECameraVideoStreamFormat value indicating 16-bit YUYV raw image encoding
OpenVR C API:
- Fixed cNewInput and rchRenderModelComponentName having an incorrect type
IVRCompositor FrameTiming:
- Added frame prediction and throttling bits to reprojection flags. Use the macros VR_COMPOSITOR_ADDITIONAL_PREDICTED_FRAMES and VR_COMPOSITOR_NUMBER_OF_THROTTLED_FRAMES for easy access. These values can be used to provide a better job at updating game simulation time for rendered frames when unable to meet native refresh rate requirements.
- Added m_nNumVSyncsReadyForUse for tracking how long each frame took to render.
- Added m_nNumVSyncsToFirstView for tracking how many vsync intervals before a given frame was first viewed (i.e. scanned out). This may differ from NumVSyncsReadyForUse if the frame was predicted further ahead since frames will never be displayed earlier than the time they were predicted to.
- See https://developer.valvesoftware.com/wiki/SteamVR/Frame_Timing for more details.
Driver API:
- Added TrackingResult_Fallback_RotationOnly, which drivers can return if they have lost positional tracking but wish to still provide rotation-only tracking.
