This guide concerns RTMP (Real-Time Messaging Protocol), a service that allows you to stream multimedia content in real time over the Internet:

• It is a proprietary protocol developed by Adobe, and its use requires the configuration of a dedicated RTMP server or the use of RTMP hosting services.
• Viewers can access the live stream using a RTMP-compatible media player, such as VLC.

By default, RTMP is blocked by Infomaniak's security rules..

• Refer to this other guide to open the corresponding port.
