As a beginner with Pi4B running Bookworm and V3 camera module with Picamera2 and Python3 I am trying to piece together code to allow my Raspberry Pi camera to be useful remotely using Connect. I have code to run a live preview and buttons to start the preview and start the preview. I also have a button to start a video capture to save a few seconds of the live video. In my code my button to launch video capture to a file is:The above is included in a main class where QWidgets display buttons and such.
The error seems to be the camera in configured state trying acquire() requiring state available, followed by Camera _init_sequence not complete.
the capture video code by itself works in a new python file - but I need it to work with all of the other code for buttons and windows and such. Would anyone be so kind as to help me over this wall? I have tried to stop the self.camera initialized at the beginning of the class code so as to be able to use the picam2 found in the def capture_video code.
Code:
def capture_video(self): try: self.timer.stop() self.camera.stop() time.sleep(2) picam2 = Picamera2() config = picam2.create_video_configuration() picam2.configure(config) picam2.start_and_record_video("my_video.mp4", duration = 10 except Exception as e: print (f"An error occurred: {e}") finally: time.sleep(2) picam2.stop()Code:
