  19 avril 2014, par user3549636

  FFmpeg isnt converting videos (or saving them, I honestly dont know) and isnt even giving me any error, whats wrong ? heres my code :

      @{
  
  WebSecurity.RequireAuthenticatedUser();
  
  var db = Database.Open("PhotoGallery");
  
  var fileName = "";
  
  var uploader = WebSecurity.CurrentUserId;
  
  var date = DateTime.Now.Date;
  
  var extention = "";
  
  if(IsPost){
  
   var numFiles = Request.Files.Count;
  
   if(numFiles <= 0){
  
       ModelState.AddError("fileUpload", "Please specify at least one photo to upload.");
  
   }
  
   else{
  
       var fileSavePath = "";
  
          var uploadedFile = Request.Files[0];
  
      fileName = Path.GetFileNameWithoutExtension(uploadedFile.FileName).Trim();
  
          extention = Path.GetExtension(uploadedFile.FileName).Trim();
  
      string ndom = Path.GetRandomFileName();
  
      var none = ndom.Remove(ndom.Length - 4);
  
      fileSavePath = Server.MapPath("~/Images/userpics/" +
  
        none + extention);
  
      uploadedFile.SaveAs(fileSavePath);
  
  
  
  
  
  string AppPath = Request.PhysicalApplicationPath;
  
  string inputPath = AppPath + "~/Images/userpics/" + fileName + extention;
  
  string outputPath = AppPath + "~/Images/userpics/" + fileName + ".flv";
  
  string imgpath = AppPath + "~/Images/userpics/thumbnails/";
  
  string cmd = " -i" + " " + inputPath + " " + outputPath;
  
  System.Diagnostics.Process proc = new System.Diagnostics.Process();
  
  proc.StartInfo.FileName = Server.MapPath("~/bin/ffmpeg.exe");
  
  proc.StartInfo.Arguments = cmd;
  
  proc.StartInfo.UseShellExecute = false;
  
  proc.StartInfo.CreateNoWindow = true;
  
  proc.StartInfo.RedirectStandardOutput = false;
  
  proc.Start();
  
  
  
  
  
       var insertCommand = "INSERT INTO Videos (FileTitle, UploadDate, UserId, ext, Name) Values(@0, @1, @2, @3, @4)";
  
       db.Execute(insertCommand, fileName, date, uploader, extention, none + extention);
  
  
  
       Response.Redirect(Href("~/Photo/View", db.GetLastInsertId()));
  
       }
  
  }
  
  }
  
  <h1>Upload Video</h1>
  
  
  
  <form method="post" enctype="multipart/form-data">
  
  @Html.ValidationSummary("Unable to upload:")
  
  <fieldset class="no-legend">
  
      <legend>Upload Photo</legend>
  
      @FileUpload.GetHtml(addText: "Add more files", uploadText: "Upload", includeFormTag: false)
  
      <p class="form-actions">
  
          <input type="submit" value="Upload" title="Upload photo" />

• using ffmpeg in asp.net razor (C#)

  18 avril 2014, par user3549636

  I know questions like this are all over the internet but I believe my case is different, I have a ASP.NET Webpage (Razor C#) and I have a whole video sharing website ready BUT I still don't understand, How can I convert videos to mp4 and webm using ffmpeg on the upload page and instead of having the original saved and added to the database i want the converted version added. heres my upload page code :

      @{
  
  WebSecurity.RequireAuthenticatedUser();
  
  var db = Database.Open("PhotoGallery");
  
  var fileName = "";
  
  var uploader = WebSecurity.CurrentUserId;
  
  var date = DateTime.Now.Date;
  
  var extention = "";
  
  if(IsPost){
  
   var numFiles = Request.Files.Count;
  
   if(numFiles <= 0){
  
       ModelState.AddError("fileUpload", "Please specify at least one photo to upload.");
  
   }
  
   else{
  
       var fileSavePath = "";
  
          var uploadedFile = Request.Files[0];
  
      fileName = Path.GetFileNameWithoutExtension(uploadedFile.FileName).Trim();
  
      extention = Path.GetExtension(uploadedFile.FileName).Trim();
  
      string ndom = Path.GetRandomFileName();
  
      var none = ndom.Remove(ndom.Length - 4);
  
      fileSavePath = Server.MapPath("~/Images/userpics/" +
  
        none + extention);
  
      uploadedFile.SaveAs(fileSavePath);
  
      var insertCommand = "INSERT INTO Videos (FileTitle, UploadDate, UserId, ext, Name) Values(@0, @1, @2, @3, @4)";
  
       db.Execute(insertCommand, fileName, date, uploader, extention, none + extention);
  
       Response.Redirect(Href("~/Photo/View", db.GetLastInsertId()));
  
       }
  
      }
  
      }
  
  <h1>Upload Video</h1>
  
  
  
  <form method="post" enctype="multipart/form-data">
