Bug描述 Describe the Bug

正常运行时10帧或者20帧后就会直接进入循环出不来，单步调试不会进入循环

def capturevideo(self, capture, queue):        
    frame_id = 0        
    while (1):            
        if queue.full():                
            time.sleep(0.1)            
        else:                
            ret, frame = capture.read()                
            if not ret:
            return  
            frame_rgb = cv2.cvtColor(frame, cv2.COLOR_BGR2RGB)
            queue.put(frame_rgb)

用release/2.5的

本地离线数据的话，可以把framequeue = queue.Queue(10)改成framequeue = queue.Queue(maxsize=0); 如果是拉流检测话，主循环有逻辑bug，当视频解码时间>检测时间时，栈中无帧，检测中断，需要改主循环while (not framequeue.empty()):，改为只要视频流指定的摄像头在开启状态下，检测不停。
