SharePoint 2013 - Document Library upload c#

Question

I'm trying to upload video using c# to SharePoint 2013 document library, every time the code runs I get a "file not found" exception, it only throws errors with .mp4 files. If I upload a jpg or any other file format for that matter it will work. What am I doing wrong? Thanks in advance for the help.

        string result = string.Empty;

        try
        {
            //site url
            ClientContext context = new ClientContext("siturl");

            // The SharePoint web at the URL.
            Web web = context.Web;

            FileCreationInformation newFile = new FileCreationInformation();
            newFile.Content = System.IO.File.ReadAllBytes(@"C:\test.mp4");
            newFile.Url = "test.mp4";

            List docs = web.Lists.GetByTitle("Learning Materials2");

            Microsoft.SharePoint.Client.File uploadFile = docs.RootFolder.Files.Add(newFile);
            context.Load(uploadFile);
            context.ExecuteQuery();
        }catch(Exception Ex)
        {

        }

Answer 1

string fileName=@"C:\test.mp4";

using (var clientContext = new ClientContext(siturl))
{
     using (var fs = new FileStream(fileName, FileMode.Open))
     {
         var fi = new FileInfo(fileName);
         var list = clientContext.Web.Lists.GetByTitle("Learning Materials2");
         clientContext.Load(list.RootFolder);
         clientContext.ExecuteQuery();
         var fileUrl = String.Format("{0}/{1}", list.RootFolder.ServerRelativeUrl, fi.Name);
         Microsoft.SharePoint.Client.File.SaveBinaryDirect(clientContext, fileUrl, fs, true);
     }
 }
