OBS - Open Broadcast Studio
Open Broadcast Studio is a free and open source software for video recording and live streaming. Used with a separate software video encoder, such as F1EJP's FreeStreamCoder, it can give a semi-professional look to the content sent to a Portsdown DATV transmitter. Create scenes made up of multiple sources including window captures, images, text, browser windows, webcams, capture cards and more.
Hardware
You will need a capable PC. It should have an Intel i5-10500 processor or better, 16GB RAM, an SSD and ideally an nVidia graphics card that supports NVENC video encoding. GTX1070, GTX1660, RTX A2000 or better are suitable models. It's also possible to use the QuickSync video encoder built into the Intel processor mentioned above or later versions with acceptable results.
Your Portsdown and PC must be connected to the same Ethernet network. Usually, you would add a cable from your Portsdown to a spare LAN port on the Internet router. Alternatively, use a small ethernet switch in the shack with a feed back to the router. Don't be tempted to use WiFi for either the Portsdown or the PC; the results will be disapointing.
Software
Your PC should be running Microsoft Windows 10 or 11 and be updated to the 22H2 release. If using an nVidia graphics card it is essential to use the latest drivers. See the nVidia website.
Download OBS v27.2.4. It's not the latest version, but can be found (amongst others) from this archive: https:// www.filehorse.com/download-obs- ... /download/ and install it. Later versions will not work with the Virtual Camera below, so ignore any requests to upgrade to a newer version.
Download the Virtual Camera v2.05 plugin from here: https://obsproject.com/forum/resources/ ... .949/[url][/url] The installer should find the OBS installation and place the files in the right place.
Download FreeStreamEncoder from here: http://www.vivadatv.org/viewtopic.php?f=78&t=1007 Create a folder in the root of your C: drive named F1EJP (C:\F1EJP) Copy the downloaded file to the new folder.
Software configuration
Once you have set the Portsdown up and connected to the network, get its IP address from the Info button at the bottom of the M2 menu. Typically it will be 192.168.1.xxx where xxx is a number from 2 to 253. Run the FreeStreamCoder and select the middle tab. Enter the Porstdown's IP address in the
OBS configuration

In Conclusion
Please note the above guide is just that a guide as every set up will be different to the next so experimentation may be necessary to get it working 100%
