You can feed pictures to your Portsdown from a PC-based video application such as vMix or OBS. For vMix the workflow is:
- Start vMix and enable the external output. The settings are described in detail here.
- Use ffmpeg running on the PC to capture the "DirectShow" output from vMix and encode it into a transport stream to be sent to the Portsdown
- Set IPTS input (from the "Encoding" menu) on the Portsdown and select transmit.
The complex part of this process is the encoding on the PC.
Use of a Batch File For Video Encoding on a PC
The notes here are based on this batch file File:vMix2PortsdownH264DVB-S2.zip, which you should download, unzip and store in a sensible place on your PC. You will need to run it every time you set up transmissions from vMix or OBS. You will also need to edit it before using it for the first time.
