I guess you’re using the Pi4? If so, I just realized that the video player object, regardless of what raw is set to, doesn’t have a texid() method attached. In fact it’s not even implemented for the Pi4. So right now chroma keying won’t work there unfortunately. I’ll see that this get fixed. Sorry about the confusion.
