splitmuxsink Filename with Datetime

[Armin Erkert]

Hi,

I can find the a wrapper and I tryed to add a SignalHandler with


public delegate void MyDelegateNewFormat(object sender, GLib.SignalArg args);

....

splitElement.AddSignalHandler("format-location", new  
MyDelegateNewFormat(NewFormat));

.....

static void NewFormat(object sender, GLib.SignalArgs args)
{
}

But running this Error

System.ArgumentException: Object of type 'System.EventArgs' cannot be  
converted to type 'GLib.SignalArgs'.
