# YouTube Live streaming

Media Blocks SDK .Net

YouTube supports RTMP (Real-Time Messaging Protocol) for live streaming, allowing content creators to broadcast live video and audio streams over the internet with minimal delay. This protocol is vital for delivering smooth, high-quality live feeds that are suitable for everything from personal vlogging to professional broadcasts.

Use the YouTubeSinkSettings class to set the parameters.
