[libcamera-devel] [PATCH] ipa: rpi: Avoid skipping IPAs on the first frame after the drop frames

[David Plowman]

We avoid skipping the IPAs while frameCount_ is less then
dropFrameCount_, indicating that these frames will not be sent to the
application. This means that when these numbers are equal then this is
the first frame the application will get, so again, we must avoid
skipping the IPAs. Consequently the test here must avoid the case of
equality.
