Simulcasting to Restreamer using OBS

Step 1: Obtain Restreamer RTMP Details

1. Open your Restreamer web interface, typically found at http://localhost:8080 or the IP of your Restreamer host machine.
2. On the Restreamer interface, navigate to the section where you define the “External RTMP Streaming”. Here, Restreamer will provide an RTMP URL and Stream Key for external broadcasting. Take note of these details.

Step 2: Configure OBS Streaming Settings

1. Open OBS and click on ‘Settings’ in the bottom right corner.
2. Click on the ‘Stream’ tab on the left sidebar.
3. In the ‘Service’ dropdown, select ‘Custom…’
4. For the ‘Server’, enter the RTMP URL you obtained from Restreamer. It should look something like: rtmp://localhost/live or based on your Restreamer host’s IP:
   • rtmp://your-restreamer-ip/live
5. For the ‘Stream Key’, input the Stream Key provided by Restreamer.
6. Click ‘OK’ to save your settings.

Step 3: Start Simulcasting

1. Back in the main OBS window, make sure you’ve selected the scenes and sources you wish to broadcast.
2. Click on the ‘Start Streaming’ button in OBS. This will begin broadcasting to Restreamer.
3. To validate that your stream is being sent to Restreamer, go back to the Restreamer web interface and check the stream’s status. You should see a live preview if everything is set up correctly.

Step 4: Forward Stream from Restreamer

Restreamer offers the possibility to relay (or forward) your stream to other platforms or servers. This feature enables you to take your single OBS stream and distribute it to multiple platforms without additional strain on your broadcasting machine.

1. Access Restreamer’s External Streaming Section:
   Open the Restreamer interface and navigate to the “External RTMP Streaming” section. Here, you’ll find options to relay your stream to external platforms.
2. Specify the External RTMP URL:
   For platforms like Twitch, YouTube Live, or Facebook Live, you’ll need to obtain the RTMP URL and stream key from the respective platform’s broadcasting settings. Input the RTMP URL in the designated field within Restreamer.
3. Enter the Stream Key:
   Alongside the RTMP URL, platforms will provide a unique stream key. Input this stream key in the designated field in Restreamer. Ensure you keep this key secret; revealing it can allow unauthorized broadcasts on your channel.
4. Optional Settings:
   Restreamer might have additional options, such as adjusting the video bitrate or resolution for the outgoing stream. Depending on your needs and the requirements of the platform you’re streaming to, you might want to adjust these settings.
5. Start Relaying the Stream:
   Once all settings are in place, click on the ‘Start’ button in Restreamer’s “External RTMP Streaming” section. Your OBS stream will now be forwarded to the platform you’ve specified.
6. Monitor Your Stream:
   It’s a good practice to monitor your stream on the destination platform for a few minutes to ensure everything is running smoothly. Check for any lag, audio desync, or other potential issues.
