If so, what other topics should we have in the agenda? I'm interested in attending, even if so far I have limited involvement in that area. Looking forward we're considering usage of ML accelerators in libcamera for various purposes, so an open ecosystem will be crucial for us. -- Regards, Laurent Pinchart
