USBCAMD_DEVICE_DATA2 structure (usbcamdi.h)

  • Article

The USBCAMD_DEVICE_DATA2 structure specifies the entry points for a camera minidriver's functions that USBCAMD calls.

Syntax

typedef struct _USBCAMD_DEVICE_DATA2 {
  ULONG                             Sig;
  PCAM_INITIALIZE_ROUTINE           CamInitialize;
  PCAM_INITIALIZE_ROUTINE           CamUnInitialize;
  PCAM_PROCESS_PACKET_ROUTINE_EX    CamProcessUSBPacketEx;
  PCAM_NEW_FRAME_ROUTINE_EX         CamNewVideoFrameEx;
  PCAM_PROCESS_RAW_FRAME_ROUTINE_EX CamProcessRawVideoFrameEx;
  PCAM_START_CAPTURE_ROUTINE_EX     CamStartCaptureEx;
  PCAM_STOP_CAPTURE_ROUTINE_EX      CamStopCaptureEx;
  PCAM_CONFIGURE_ROUTINE_EX         CamConfigureEx;
  PCAM_STATE_ROUTINE                CamSaveState;
  PCAM_STATE_ROUTINE                CamRestoreState;
  PCAM_ALLOCATE_BW_ROUTINE_EX       CamAllocateBandwidthEx;

Members

Sig

Reserved. Do not use.

CamInitialize

Pointer to the camera minidriver defined CamInitialize callback function. This entry point is required.

CamUnInitialize

Pointer to the camera minidriver defined CamUnInitialize callback function. This entry point is required.

CamProcessUSBPacketEx

Pointer to the camera minidriver defined CamProcessUSBPacketEx callback function. This is an optional entry point. If the minidriver does not implement this function, it must point to an empty function.

CamNewVideoFrameEx

Pointer to the camera minidriver defined CamNewVideoFrameEx callback function. This is an optional entry point. If the minidriver does not implement this function, it must point to an empty function.

CamProcessRawVideoFrameEx

Pointer to the camera minidriver defined CamProcessRawVideoFrameEx callback function. This is an optional entry point. If the minidriver does not implement this function, it must point to an empty function.

CamStartCaptureEx

Pointer to the camera minidriver defined CamStartCaptureEx callback function. This entry point is required.

CamStopCaptureEx

Pointer to the camera minidriver defined CamStopCaptureEx callback function. This entry point is required.

CamConfigureEx

Pointer to the camera minidriver defined CamConfigureEx callback function. This entry point is required.

CamSaveState

Pointer to the camera minidriver defined CamSaveState callback function. This is an optional entry point. If the minidriver does not implement this function, it must point to an empty function.

CamRestoreState

Pointer to the camera minidriver defined CamRestoreState callback function. This is an optional entry point. If the minidriver does not implement this function, it must point to an empty function.

CamAllocateBandwidthEx

Pointer to the camera minidriver defined CamAllocateBandwidthEx callback function. This entry point is required.

CamFreeBandwidthEx

Pointer to the camera minidriver defined CamFreeBandwidthEx callback function. This entry point is required.

Remarks

A camera minidriver passes a USBCAMD_DEVICE_DATA2 structure to USBCAMD as a parameter to USBCAMD service USBCAMD_InitializeNewInterface.

Camera minidrivers that must be backward compatible with the original USBCAMD library must use the USBCAMD_DEVICE_DATA structure.
