Hi!
I would like to capture video at less than 15fps using picamera2. This is so I can have longer exposure for capturing low light video. I am using an arducam noir picamera with an imx219 image sensor.
to capture the video, I am using the python script below:This code runs successfully if I change FrameRate to 15 (test.mp4 captured at 15fps). When I run it with FrameRate at 12, I get the following output:This results in nothing being written to test.mp4. I also tried adding ""camera_timeout_value_ms": 5000000," to rpi_apps.yaml in case the issue was just the dequeue timer, but that resulted in the following output, along with nothing being written to test.mp4:Any ideas as to why I can only capture a minimum of 15 fps? I also have an issue where I can't set exposure for image capture over ~90000us, unsure if it is related (may make another post with those details if not).
Thanks in advance!
