VC++視訊採集的步驟

VC6.0視訊採集的步驟:
1、插入攝像頭,安裝驅動 VCap2800 USB2.0 DRV(windows 7)或者Vcap2820 sdk,兩者依次嘗試
注意:驅動有一下幾種,如果USB2.0 DRVB不成功!!可以換驅動VCap2820 sdk進行嘗試!!!
2、G:\VC++視訊採集資料\USB2800\Vcap2820 sdk\Vcap2820 sdk目錄下的 devwdm.ax 放到c:\windows\system32\目錄下
3、開啟 “執行”,輸入 Regsvr32 c:\windows\system32\devwdm.ax 進行註冊驅動
4、建立VC工程,基於對話方塊
5、新增devwdm.dll devwdm.h devwdm.lib到專案中,這些是攝像頭的相關API
5、在StdAfx.h檔案中載入動態連結庫
#pragma comment(lib,"devwdm.lib")
- // stdafx.h : include file for standard system include files,
- // or project specific include files that are used frequently, but
- // are changed infrequently
- //
- #if !defined(AFX_STDAFX_H__1357FC0D_0191_4DD3_8CB5_4A15DA0B970C__INCLUDED_)
- #define AFX_STDAFX_H__1357FC0D_0191_4DD3_8CB5_4A15DA0B970C__INCLUDED_
- #if _MSC_VER > 1000
- #pragma once
- #endif // _MSC_VER > 1000
- #define VC_EXTRALEAN // Exclude rarely-used stuff from Windows headers
- #include <afxwin.h> // MFC core and standard components
- #include <afxext.h> // MFC extensions
- #include <afxdisp.h> // MFC Automation classes
- #include <afxdtctl.h> // MFC support for Internet Explorer 4 Common Controls
- #ifndef _AFX_NO_AFXCMN_SUPPORT
- #include <afxcmn.h> // MFC support for Windows Common Controls
- #endif // _AFX_NO_AFXCMN_SUPPORT
- //註冊動態連結庫
- #pragma comment(lib,"devwdm.lib")
- //{{AFX_INSERT_LOCATION}}
- // Microsoft Visual C++ will insert additional declarations immediately before the previous line.
- #endif // !defined(AFX_STDAFX_H__1357FC0D_0191_4DD3_8CB5_4A15DA0B970C__INCLUDED_)
6、新增標頭檔案到響應的cpp應用檔案中,進行測試
- #include "devwdm.h"
- void CVideoDemoDlg::OnOK()
- {
- // TODO: Add extra validation here
- devwdm_InitCard(0,m_static.m_hWnd,300,400);//初始化
- devwdm_StartVideoPreview(0);//啟動
- // CDialog::OnOK();
- }
