Hi Naush Thanks for the patch, I have been eagerly awaiting this set!

Is it worth remarking that they can be set to the same values to give a fixed fps mode of operations? Or is that too obvious to mention?

Add a float array control (controls::FrameDurations) to specify the minimum and maximum (in that order) frame duration to be used by the camera sensor. Signed-off-by: Naushir Patuck <naush@raspberrypi.com> --- src/libcamera/control_ids.yaml | 13 +++++++++++++ 1 file changed, 13 insertions(+)
