If I want to collect desktop data and filter some windows, what API can Microsoft provide? The magnification API was used before, but the key API MagSetImageScalingCallback is no longer maintained, and there is a memory leak problem with this API, which can not be used well. So I'd like to ask what new API can I use to support this function? Mainly want to get YUV data
You can check Capturing an Image to see if it helps. YUV bitmap is supported. For filter, you can use SetWindowDisplayAffinity with WDA_EXCLUDEFROMCAPTURE (new introduced in 20H1) (excluded windows area is transparent) or with WDA_MONITOR (excluded windows area is black)

Worth to mention that starting from version 20H1 old API works BAD and it's broken and nobody cares. WDA_MONITOR just does not work.
So it's pure regression, and this stupid bug exist in both 20H1 and 20H2 in all minor build from .1 to the latest.
