Using OBS with Portsdown

OBS can be used as a fully flexible video source for the Portsdown DATV system. The program interfaces in to the Portsdown over a wired network connection via an ffmpeg script developed by Evariste F5OEO.

Preparing the system

Software

As well as downloading OBS and ensuring it runs on your PC, you will also need to download ffmpeg from https://ffmpeg.org/ - ffmpeg should then be installed on your PC at C:/ffmpeg

Hardware

You will need to setup the Portsdown to talk to your PC via a network cable, WiFi wont work reliably. I set the Portsdown up with a fixed IP of 10.0.0.1 by adding the text ip=10.0.0.1 to the cmdline.txt file found in the root of your SD card.

Once you have set the Portsdown up and can confirm the network is working, you need to set up OBS.
