I'm trying to get live feed from TPLink TL-SC3171G IP cam in C# app. I've tried using AForge.NET library but no luck. The sample code from AForge.NET doesn't work for me. I'm getting "The remote server returned an error: (401) unauthorized access."
I can access the cam via browser with basic ip adress: "http://192.168.168.20". In app I've tried with:
"http://username:password@192.168.168.20""http://username:password@192.168.168.20:port"Can you please help me with some direction. It really doesn't have to be AForge.NET library.
This is the code:
