I am using the desktop duplication API from Windows to capture the desktop and then I want to stream it using ffmpeg libraries.
The thing is that the desktop duplication API return smaller rectangles with the parts of the screen that has changed. I there some way to pass these partial updates to ffmpeg directly to encode them to a video? They just tell fmpeg what parts of the image have changed from the previous one.
I know that ffmpeg, the application can capture the desktop using the desktop duplication API, but I don't know if it's also taking into account this special feature of desktop duplication to extract the changed parts of the desktop.
