c# record from adult stream and save video

Hello, for my customer I need a c# application to record streaming from chaturbate. Its adult webcam streaming site, where models streams their content. Stream is public. Perfect way is to add urls of streams to app and the app starts recording those streams. When stream ends, app saves the video to the folder. You can find working solution in python on github (or I can send it to you). It works well for me, but I need working solution in C# for future edits. So if you know python, it should be piece of cake. I expect clean code with description. Its important. Thank you, Matej
