USBCAMD_DEVICE_DATA structure (usbcamdi.h)

This structure is obsolete and is provided to maintain backward compatibility with the original USBCAMD. New camera minidrivers should use the USBCAMD_DEVICE_DATA2 structure.

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

Syntax

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.

CamProcessUSBPacket

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

CamNewVideoFrame

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

CamProcessRawVideoFrame

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

CamStartCapture

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

CamStopCapture

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

CamConfigure

Pointer to the camera minidriver defined CamConfigure 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.

CamAllocateBandwidth

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

CamFreeBandwidth

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

Remarks

A camera minidriver passes a USBCAMD_DEVICE_DATA structure to USBCAMD as a parameter to the USBCAMD library routine USBCAMD_AdapterReceivePacket in the original USBCAMD.
