phase locked loop for framerate

[michaelchimento]

hi, i'm interested in implementing a PLL to adjust the framerate for the v3 camera (similar to a previous implementation in raspivid https://github.com/inastitch/raspivid-inatech), although tbh libcamera is greek to me, and i'd rather write it in python. I figured I might save myself some time if someone could point me to where the frame callbacks happen in picamera2. Thanks for your help!

Hi, you can set the framerate directly as follows:

picam2.set_controls({'FrameRate': 30.0})

Does that help?
