Custom RTMP is a feature that allows you to connect your streaming channel to a video broadcaster with specific parameters provided by the streaming platform of choice. 

To use Custom RTMP, you will need two RTMP values from the platform you want to stream to: 

· Server URL

· Stream Key / Stream ID

Using a custom RTMP (Real-Time Messaging Protocol) setup on YouTube offers several advantages:

1. Increased control and flexibility: With a custom RTMP setup, you have more control over your streaming workflow. You can adjust the streaming parameters and settings according to your unique requirements, including the video bitrate, resolution, and audio quality. This level of customization allows you to optimize your stream for the best possible viewer experience.

2. Compatibility with third-party software and hardware: Custom RTMP allows you to integrate third-party software and hardware solutions into your streaming setup. You can use professional broadcasting software or hardware encoders that offer advanced features and functionalities. This flexibility enables you to enhance the production quality and incorporate additional elements like graphics, overlays, and multiple camera angles.

3. Private or restricted streaming: A private or restricted live streaming event is a broadcast meant to be streamed to a select group of people rather than to the public. Using a custom RTMP setup, you can stream privately or restrict access to your stream. This is useful when limiting your viewership to specific individuals or groups. For example, you can host an internal company event or provide exclusive content to a select audience.

4. Branding and customization: A custom RTMP setup lets you brand your live streams. You can overlay graphics, logos, lower thirds, and other visual elements to personalize the stream and reinforce your brand identity. This branding helps create a professional and cohesive streaming experience for your viewers.

5. Redundancy and backup options: Custom RTMP setups often provide options for redundancy and backup streams. You can configure failover mechanisms that automatically switch to backup servers or streams if the primary connection experiences issues. This ensures a more reliable and uninterrupted streaming experience for your viewers.

6. Analytics and tracking: Custom RTMP setups may offer more detailed analytics and tracking options than the standard YouTube streaming interface. You can integrate analytics tools or access more comprehensive data about your viewership, such as audience demographics, viewer engagement, and viewing duration. These insights can help you measure the success of your live streams and make informed decisions for future events.

Limitations of Custom RTMP Live Streaming

One important point to remember about using custom RTMP for live streaming is that while you can broadcast to new destinations and platforms, you cannot display live comments on your show. Instead, you would need to either monitor them on a separate screen or monitor and mention them during your broadcast or go back and respond to them after the broadcast has ended.

In addition, you cannot see the number of live viewers on your broadcast or schedule your live stream.

It’s important to note that using a custom RTMP setup on YouTube requires technical expertise and additional setup compared to using the native YouTube streaming interface. It’s recommended to test and familiarize yourself with thoroughly the setup before broadcasting live to ensure a smooth streaming experience.
