OBS Multiple RTMP Output Plugin is a tool for streaming into several destinations simultaneously from OBS Studio. Generally, by default, with OBS Studio, one can stream to only one destination at a time. However, with this plugin, you can send your stream to multiple destinations—for example, YouTube, Twitch, and Facebook Live—at the same time.
Open the Multiple RTMP Outputs Plugin page on OBS. Click 'Go to download'.
Choose the plugin for your operating system and install it.
Select Docks in the header bar. You can see the 'Multiple Output' plugin has been added.
Select it to add Custom RTMP destinations by clicking 'Add new target'.
