使用 python 降低相机的 FPS

Question

我正在从显示原始 fps 设置为 25 的相机读取帧。我正在尝试将其 FPS 降低到大约 6-7。

我同时读取多个摄像头并将帧附加到各个摄像头的 deque。我在这里使用了线程。

到目前为止，我正在这样做，但运气不好

while True:
    try:
        # Read next frame from stream and insert into deque
        status, frame = self.capture.read()
        frame = cv2.resize(frame, (640, 360))

        if status:
            self.deque.append(frame)
        else:
            self.capture.release()
            self.online = False

frame_count = 1
        
while True:
    try:
    # Read next frame from stream and insert into deque
    status, frame = self.capture.read()
                    
    if frame_count % 4 == 0:
        frame = cv2.resize(frame, (640, 360))

        if status:
            self.deque.append(frame)
        else:
            self.capture.release()
            self.online = False
    frame_count += 1
