Making it a versatile solution for an array of interactive content delivery needs. This gives a major reason for RTMP to remain relevant and popular despite the emergence of more new streaming protocols. 

Moreover, RTMP streaming protocol works on TCP (transmission control protocol). It sends the smaller data in a static order until they reach the final destination. It is being widely used for ingesting the data, performing streaming, and then transcoding it into HLS for multi-device support. Most streaming platforms like YouTube, Facebook, and more are leveraging RTMP to ensure low latency and stability. 

Pros of RTMP

Here are the basic advantages of using RTMP streaming that can be achieved while incorporating it into your video streaming:
