PCAM_NEW_FRAME_ROUTINE callback function

Description

[CamNewVideoFrame is not supported and may be altered or unavailable in the future. Instead, use CamNewVideoFrameEx. ]

A camera minidriver's CamNewVideoFrame callback function initializes a new video frame context structure.

Parameters

`DeviceContext`

Pointer to the camera minidriver's device context.

`FrameContext`

Pointer to the camera minidriver's frame context.

Remarks

Camera minidrivers that must maintain backward compatibility with the original USBCAMD must use the USBCAMD_DEVICE_DATA structure and its associated callback functions (that is, callback functions that do not contain the "Ex" suffix).

USBCAMD calls the camera minidriver's CamNewVideoFrame callback function at IRQL = DISPATCH_LEVEL.

This function is optional.
