It should work as-is - the image I tested wasn't against 1.2M3, but that's what I'll now build and try again myself. So just for more information, all this used to work using emgd 1.8, but the same thing with 1.10 no longer does? Could you also send the debug output for that and also the output of 'gst-inspect'? The licensing implications are mentioned in the EMGD documentation, but I've also discussed them with Jeffrey Moore, so you might want to talk to him about the details for your project.
