Simulcasting is works with the following encoders only:
- Livestream Producer
- Livestream Tricaster Plug-in
- Livestream Studio (including HD31, HD51, HD550, etc.)
- Broadcaster mini
- Broadcaster Pro
- Livestream app for iOS (iPhone, iPad)
- Livestream app for Android
- Teradek VidiU/VidiU Pro
- Stream via RTMP from any third-party encoder (e.g. OBS)
If your encoder is not listed here (e.g. Broadcaster V1, Teradek Cube) and has a direct streaming integration with Livestream, then, unfortunately, it will not be able to simulcast.
All software, firmware, and hardware need to be updated to their most recent versions in order to successfully simulcast.
