Hi Tiago,
this is a very smart solution, thank you so much for your effort. Actually I try to stream a camera by python script,
but is very very slow, in your C# app it works on realtime. Is it possible to find a way to embedded the streamer into
javascript html file, so it will be easier to use it?

Many thanks

Hi @TiagoPrata i'm creating several streams from different pcs to monitor them in a single page but it's only letting me open 6 streams and no more. I don't know if this is a thread pool limit or a browser limitation, as some say, becose it doesn't work in any of mine (chrome, edge and firefox). I'm working on a Windows machine by the way. Can you help me, please?
