python連接海康攝像頭,並以彈出框的方式播放實時視頻流,python
這種方式是以彈出框的形式播放。本地測試能夠,實際業務場景不建議使用。能夠採用rtsp轉rtmp的方式ide
@shared_task def parse_video(rtsp_address=None): winname = 'Video' if not rtsp_address: raise exceptions.ParseError('攝像頭rstp地址錯誤!') cap = cv2.VideoCapture(rtsp_address) if not cap.isOpened(): raise exceptions.ParseError('視頻播放失敗!') while cap.isOpened(): ret, frame = cap.read() if not ret: break cv2.putText(frame, 'Please press "ESC" to close the window', (900, 20), cv2.FONT_HERSHEY_SIMPLEX, 0.5, (55, 255, 155), 1) cv2.imshow(winname, frame) k = cv2.waitKey(1) if cv2.getWindowProperty(winname, cv2.WND_PROP_AUTOSIZE) < 1: break if k == 27: break cap.release() cv2.destroyAllWindows()
