用AVIFile函数制做AVI文件基本步骤

• AVIFile,AVIFileOpen,AVIFileCreateStream....制做AVI文件，基相实现方法。

  AVIFileInit();

  //创建AVI文件

  if(AVIFileOpen(&m_aviFile,aviFileFullName,OF_CREATEOF_WRITE,0))

  {

  MessageBox("create file '"+aviFileFullName+"' error");

  return;

  }

  //设置视频流格式

  AVISTREAMINFOW m_aviVideoStreamInfo;

  m_aviVideoStreamInfo.fccType = streamtypeVIDEO;

  m_aviVideoStreamInfo.fccHandler = 0;

  m_aviVideoStreamInfo.dwFlags = 0;

  m_aviVideoStreamInfo.dwCaps = 0;

  m_aviVideoStreamInfo.wPriority = 0;

  m_aviVideoStreamInfo.wLanguage = 0;

  m_aviVideoStreamInfo.dwRate = 5; //每秒5帧

  m_aviVideoStreamInfo.dwScale = 1;

  m_aviVideoStreamInfo.dwQuality = 0;

  m_aviVideoStreamInfo.dwSuggestedBufferSize = m_ImageWidth*m_ImageHeight*3;

  m_aviVideoStreamInfo.dwStart = 0;

  m_aviVideoStreamInfo.dwInitialFrames = 0;

  m_aviVideoStreamInfo.dwSampleSize = 0;

  m_aviVideoStreamInfo.rcFrame.left = 0;

  m_aviVideoStreamInfo.rcFrame.top = 0;

  m_aviVideoStreamInfo.rcFrame.right = m_ImageWidth;

  m_aviVideoStreamInfo.rcFrame.bottom = m_ImageHeight;

  m_aviVideoStreamInfo.dwEditCount = 0;

  m_aviVideoStreamInfo.dwFormatChangeCount = 0;

  strcpy((char *)m_aviVideoStreamInfo.szName,"ScreenCap.avi");

  m_aviVideoStreamInfo.dwLength = 0;

  //设置音频流格式

  AVISTREAMINFOW m_aviAudioStreamInfo;

  m_aviAudioStreamInfo.fccType = streamtypeAUDIO;

  m_aviAudioStreamInfo.fccHandler = 0;

  m_aviAudioStreamInfo.dwFlags = 0;
