  • 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 &lt;= 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()));
    
     }

var uploader = WebSecurity.CurrentUserId;
    
var date = DateTime.Now.Date;
    
var extention = "";
    
if(IsPost){
    
 var numFiles = Request.Files.Count;
    
 if(numFiles &lt;= 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();

    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;
