RTMP (Real-Time Messaging Protocol) pull refers to the process of retrieving or pulling a live video stream using the RTMP protocol. RTMP is a protocol designed for high-performance transmission of audio, video, and data over the internet. It is commonly used for live streaming.

In the context of PullRTMP :

1. RTMP Protocol: RTMP is a streaming protocol developed by Adobe Systems for the transmission of audio, video, and data over the internet. It operates on top of the Transmission Control Protocol (TCP).
2. Pulling the Stream: When you “pull” an RTMP stream, it means you are receiving or fetching the stream from a source server. This is in contrast to “pushing” a stream, where the source server actively sends the stream to one or more destination servers.
3. Use Cases: pullRTMP  is often used in scenarios where you want to redistribute a live stream from its source to other servers or services. For example, a content delivery network (CDN) might use pullRTMP to grab a live stream from a broadcaster’s server and distribute it to viewers around the world.
4. Configuration: To perform an RTMP pull, you typically need to configure the server or device that will be pulling the stream to connect to the source server where the live stream is originating. This involves specifying the RTMP URL or stream key of the source stream.

It’s worth noting that while RTMP has been widely used in the past for live streaming, newer protocols like HLS (HTTP Live Streaming) and DASH (Dynamic Adaptive Streaming over HTTP) have gained popularity due to their compatibility with a broader range of devices and network conditions. Always consider the specific requirements of your streaming setup and the compatibility of the chosen protocol with your target audience’s devices
