I was thinking that it would be faster if I send just the modified parts to
the encoder.

If you pass the entire frame to the codec, it will figure out the changed
regions itself, so you don't need to worry about compression ratio.

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.
