PCAM_STOP_CAPTURE_ROUTINE_EX callback function

Description

A camera minidriver's CamStopCaptureEx callback function performs any processing after the stream is stopped.

Parameters

BusDeviceObject

Pointer to the camera minidriver's device object created by the USB hub.

DeviceContext

Pointer to the camera minidriver's device context.

StreamNumber

Indicates the stream number.

Return value

CamStopCaptureEx returns STATUS_SUCCESS or an appropriate error code. This return value is the completion code for the read IRP.

Remarks

USBCAMD calls the minidriver's CamStopCaptureEx callback function immediately after the isochronous video stream is stopped. Typically, a camera minidriver selects an alternate setting within the USB video streaming interface that uses no additional bandwidth.

The original USBCAMD does not call CamStopCaptureEx.

This function is required.
