java - android - 使用 VideoView 的多个实例时出错

Question

我想要一个以线性布局显示两个(或更多)视频 View 的 Activity 。

使用带有本地文件的 videoview 作为数据源一切正常，但是通过流 rtsp 使用视频我有一个 Mediaplayer 错误代码，如 (1,1)，通常第一个视频正确显示，第二个显示错误。

我一次尝试两个流，它们都有效，所以没有格式错误。

我阅读了有关媒体播放器资源发布的内容(link)，但我需要显示每个实时视频。

这是我 Activity 中的代码:

   try{
    videoView = (VideoView) findViewById(R.id.videoView1);
    Uri video = Uri.parse(urlVideo+"1"); 
    videoView.setVideoURI(video);
    videoView.start();

    videoView2 = (VideoView) findViewById(R.id.videoView2);
    Uri video2 = Uri.parse(urlVideo+"0");
    videoView2.setVideoURI(video2);
    videoView2.start();
}
catch (Exception e) { 
    e.printStackTrace(); 
}

这是 logcat 上的完整错误:

我还没有见过可以支持超过 4 个 VideoView(或媒体播放器、stagefright 或 OpenMAX)并发 Activity 实例的设备。如果您的 CPU 足够强大，您应该使用软件解决方案(ffmpeg 或 gstreamer)。
