在PyQt4窗体中播放mjpg-streamer输出视频
最近买了TP-LINK703N路由器，按照论坛中的资料成功刷入openwrt。安装mjpg-streamer后，可正常在网页中观看视频。后面打算自己写个上位机程序，就研究了下如何用在基于PyQt4的窗口中播放视频。以下示例代码可正常播放视频，希望对有相同需求的同学有所帮助。两个文件：PyStreamClientUi.py，PyStreamClient.py。双击PyStreamClient.py运行# -*- coding: utf-8 -*-
#filename: PyStreamClientUi.py

请问楼主，用的703N刷的openwrt挂载的是什么摄像头？UVC的摄像头要怎么安装驱动呢？
