2.5.5 AdvDVP_Start

Syntax

int AdvDVP_Start(int nDevNum, int SwitchingChans,
HWND Main, HWND hwndPreview)

Parameters

nDevNum:

Specifies the device number(0~3).

SwitchingChans: Single video input or switching

between video muxes.

0:

single

channel.

1: two channels (mux0, mux1).

2: three channels (mux0, mux1,
mux2).

3: four channels (mux0, mux1,
mux2, mux3).

Main:

A main window handle.

hwndPreview:

A windows handle for display area.
This parameter is only valid, when
the “SwitchChans” is zero. When
the value of this parameter is NULL,
the video will not be rendered.

Return Value

SUCCEEDED: Function

succeeded.

FAILED:

Function

failed.

SDKINITFAILED:

SDK not initialized.

DEVICENUMERROR:

Invalid device number.

Description

This function starts video capturing on a specified
capture port.
The capture state would be set as “RUNNING” after a
successful start. If the channels share frames (i.e.
