Question

我正在使用Microsoft Interop Library从PowerPoint演示文稿创建视频。PowerPoint演示文稿包含内部嵌入式视频和动画。

Interope库运行良好，当在Visual Studio中运行应用程序时，我们能够成功创建视频。当我们在IIS服务器中部署代码时，视频创建仍然可以成功进行，但是，视频内部嵌入在演示文稿中不起作用。

是否有人对IIS和Visual Studio的这种行为有任何了解？ 我们已经检查了IIS中的Mime类型以及所有扩展名.mov。 .mp4已经存在

这是代码：

var videoRelativePath = "\\UserData\\User_" + templateObj.UserId + "\\VideoTemplate\\Vid_" + timeStampNew + ".mp4";
            var videoPath = _environment.ContentRootPath + videoRelativePath;
            ErrorLoging.LogMessageInLogFile(System.DateTime.Today.ToLongTimeString() + " - " + "Initializing powerpoint application for video creation");
            Microsoft.Office.Interop.PowerPoint.Application ppApp = new Microsoft.Office.Interop.PowerPoint.Application();
            Microsoft.Office.Interop.PowerPoint.Presentations oPresSet = ppApp.Presentations;
            ErrorLoging.LogMessageInLogFile(System.DateTime.Today.ToLongTimeString() + " - " + "OPening the presentation Instance");
            Microsoft.Office.Interop.PowerPoint._Presentation oPres = oPresSet.Open(
              videoFileNameForConversion,MsoTriState.msoFalse,MsoTriState.msoFalse,MsoTriState.msoFalse);
            //System.Threading.Thread.Sleep(180);
            oPres.UpdateLinks();
            try
            {
                //CreateVideo(string FileName, bool UseTimingsAndNarrations, int DefaultSlideDuration, int VertResolution, int FramesPerSecond, int Quality)
                ErrorLoging.LogMessageInLogFile(System.DateTime.Today.ToLongTimeString() + " - " + "Calling CreateVideo ");
                oPres.CreateVideo(videoPath);
                while (oPres.CreateVideoStatus == Microsoft.Office.Interop.PowerPoint.PpMediaTaskStatus.ppMediaTaskStatusInProgress || 
                oPres.CreateVideoStatus == Microsoft.Office.Interop.PowerPoint.PpMediaTaskStatus.ppMediaTaskStatusQueued)
                {
                    System.Threading.Thread.Sleep(10000);
                }
             }

            catch (Exception er)
            {
                ErrorLoging.LogErrorInLogFile(er);

            }
