How to send stream to server without any compression?
Any video you plan to stream from a host machine to another endpoint, or multiple endpoints, will have to be encoded. The question is what is your source? Are you streaming a live video feed? If so, in order to stream uncompressed you’d first have to have your capture setup to injest the video as an uncompressed format, 4:4:4. Even with just 1080, you are talking huge amounts of data. 

For uncompressed, to stream over the internet, youre going to need a serious rock solid network uplink... 1000mbps up or greater depending on the frame size.
