Nginx RTMP is a TCP-based convention intended to keep up low-dormancy associations for sound and video spilling. To expand the measure of information that can be easily transmitted, streams are part into littler sections called parcels. RTMP additionally characterizes a few virtual channels that work autonomously of one another for bundles to be conveyed on. This implies video and sound are conveyed on discrete channels all the while, To  get more information click here to visit the official website.
