C#使用PPT组件的CreateVideo方法实现视频生成

POWERPOINT.Application objApp = null; //初始PPT应用对象
POWERPOINT.Presentation objPresSet = null; //初始文稿对象
 
objApp = new POWERPOINT.Application(); //创建实例化PPT应用
objApp.DisplayAlerts = POWERPOINT.PpAlertLevel.ppAlertsNone; //关闭一切提示
 
string pptfilename="c:\\test.pptx"; //要打开的PPT文件名
 
//打开文件，创建实例化PPT文稿对象
objPresSet = objApp.Presentations.Open(pptfilename, Microsoft.Office.Core.MsoTriState.msoFalse, Microsoft.Office.Core.MsoTriState.msoFalse, Microsoft.Office.Core.MsoTriState.msoFalse);
 
string MP4_FileName = "c:\\test.mp4";    //输出的MP4文件名
bool UseTimingsAndNarrations = false; //指示是否使用计时和旁白
int DefaultSlideDuration = 5;  //观看幻灯片的持续时间（单位：秒）
int VertResolution = 720;   //幻灯片的分辨率
int FramesPerSecond = 30;   //每秒的帧数
int Quality = 100;  //幻灯片的质量水平，最高100
 
//创建视频开始
objPresSet.CreateVideo(MP4_FileName, UseTimingsAndNarrations, DefaultSlideDuration, VertResolution, FramesPerSecond, Quality);
 
//由于该方法是异步的，需要实时监控生成进度
while (objPresSet.CreateVideoStatus == POWERPOINT.PpMediaTaskStatus.ppMediaTaskStatusInProgress)
{
    System.Threading.Thread.Sleep(1000); //间隔1秒监控1次
}
 
//生成完毕，执行其它操作...
