如何在Android中设置纵向rtsp流视频的方向？

Question

我正试图以纵向方式播放rtsp视频流，任何人都可以帮我吗？

我做过类似的事情 videoView.setVideoPath("rtsp://172.18.24.105:1234"); videoView.requestFocus(); videoView.start();

Video is playing in this way,Click to see 下面是我已经开始rtsp流的活动代码，它也可以从rtsp url播放rtsp流，问题是rtsp视频流正在播放其他方向，如上图链接。 有人可以帮我这个吗？我的活动代码中是否存在启动rtsp流可能影响视频流方向的问题
