I have wasted another week trying to get this to work. I have attached the sample code I am using and images with the resultant output. I have also attached my system analyser output.
As far as I can see from the limited samples and documentation, LumaKeyEnable does not work and is broken. If you are able to let me know if this is a bug then can you suggest a work-around or how I could implement a more useful ChromaKey functionality in hardware? I am on a tight schedule and need to deliver my project.
