Stream SRT with OBS or between OBS instances

Send SRT video between OBS instances across internet or local LAN

tl;dr;

• On your source OBS, open the OBS "stream" settings
  
  SERVER:  replace the IP/FQDN and port to reflect your system
  srt://Destination_WAN_or_LAN_IP_Address:PORT?latency=200000
  
  STREAM KEY:
  leave entry blank
  
  
• On the destination OBS (OBS receiving the SRT feed)
• create a "media source"
• UNCHECK "Local File"
• Uncheck "Restart playback when source becomes active"
• for "INPUT" put in the following syntax
  
  srt://LocalOBS_IP:PORT?mode=listener&latency=5000

• If you are sending this video across the internet, Open firewall ports on internet for your receiving OBS to allow the UDP port into your network and point it to the IP of your OBS that is receiving the video
• Click start stream, video should show up

DETAILED instructions

On your source OBS system

• go to the stream settings and put in the following:
  
  srt://Destination_WAN_or_LAN_IP_Address:PORT?latency=200000
  
  Example syntax.  This example in this document uses port 37491.
  srt://333.444.555.666:37491?latency=200000

SET OBS TO RECIEVE SRT VIDEO

• In OBS, we'll create a new scene called "SRT LISTENER" 
• create a Media Source 

Inside MEDIA SOURCE

• UNCHECK "Local File"
• Uncheck "Restart playback when source becomes active"
• in "INPUT" we'll put in the following syntax
  srt://LocalOBS_IP:PORT?mode=listener&latency=5000
  
  "LocalOBS_IP" is the local IP of the computer running your receiving OBS application.

If the computer's IP is 192.168.0.5, the IP we put in the OBS system.  This example uses port 37491.

    srt://192.168.0.5:37491?mode=listener&latency=5000

Select OK to save your changes.

Now you need to open the port in your firewall of your receiving network connection.
You will need to open a UDP port and point it to the IP of your OBS receiving computer. 

In this example, if you were sending the video across the internet, you would open port 37491 and point it to 192.168.0.5
Search for instructions for your router's firewall configuration settings to get details how to do this.

Assuming the receiving end is ready, press "START STREAMING" on your source OBS and it show the green box in the lower right corner of OBS.
