While play media (using Play() method) with https url getting exception:

An unhandled exception of type 'System.NullReferenceException' occurred in PresentationCore.dll

Additional information: Object reference not set to an instance of an object.

Is there any alternate way to make it working?

I have written below code:

MeMediaElement.Source = new Uri(txtPath.Text, UriKind.RelativeOrAbsolute);
MeMediaElement.Play();

  • I'm afraid there is not an easy solution for that. What about downloading file to local disk and then streaming? – Orkun Bekar Dec 29 '15 at 08:39
  • No. that will be not good way when file size is very large like More then 10MB. – user3378939 Dec 29 '15 at 11:39
