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.
