YOLO OpenCV Python 无法显示来自 RTSP 的视频

如何解决YOLO OpenCV Python 无法显示来自 RTSP 的视频

我用 Yolo 测试了 openCV，它在使用网络摄像头时没有问题。我尝试通过此代码使用来自 RTSP 的视频。

net = cv2.dnn.readNet('yolov3_training_last.weights','yolov3_testing.cfg'
classes = []

with open("classes.txt","r") as f:
    classes = f.read().splitlines()

cap = cv2.VideoCapture('rtsp://admin:123456@192.168.10.9:554')

font = cv2.FONT_HERShey_PLAIN
colors = np.random.uniform(0,255,size=(100,3))

while(True):
    _,img = cap.read()
    height,width,_ = img.shape

    
    blob = cv2.dnn.blobFromImage(img,1/255,(416,416),(0,0),swapRB=True,crop=False)
    net.setInput(blob)
   
    output_layers_names = net.getUnconnectedOutLayersNames()
    
    layerOutputs = net.forward(output_layers_names)
    
    Boxes = []
    confidences = []
    class_ids = []
    cv2.imshow('frame',img)
    if cv2.waitKey(1) & 0xFF == ord('q'):
        cv2.destroyAllWindows()
        break

当我运行这段代码时，它只显示一张图片，然后它就冻结了。当我在 layerOutputs = net.forward(output_layers_names) 行评论时，程序不会冻结。如何解决？
