android-无法使用Vitamio运行实时流
作者：互联网
我正在尝试使用Vitamio运行RTSP视频流,更新它以通过VideoViewDemo活动运行流后,我正在使用Vitamio-sample：
public class VideoViewDemo extends Activity {
/**
* TODO: Set the path variable to a streaming video URL or a local media file
* path.
*/
private String path = "rtsp://user:password@<stream-ip>:554";
private VideoView mVideoView;
private EditText mEditText;
@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
if (!LibsChecker.checkVitamioLibs(this))
return;
setContentView(R.layout.videoview);
mEditText = (EditText) findViewById(R.id.url);
mVideoView = (VideoView) findViewById(R.id.surface_view);
if (path == "") {
// Tell the user to provide a media file URL/path.
Toast.makeText(VideoViewDemo.this, "Please edit VideoViewDemo Activity, and set path" + " variable to your media file URL/path", Toast.LENGTH_LONG).show();
return;
} else {
/*
* Alternatively,for streaming media you can use
* mVideoView.setVideoURI(Uri.parse(URLstring));
*/
mVideoView.setVideoPath(path);
mVideoView.setMediaController(new MediaController(this));
mVideoView.requestFocus();
//mVideoView.setVideoURI(Uri.parse(path));
mVideoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
@Override
public void onPrepared(MediaPlayer mediaPlayer) {
// optional need Vitamio 4.0
mediaPlayer.setPlaybackSpeed(1.0f);
}
});
}
}
public void startPlay(View view) {
String url = mEditText.getText().toString();
path = url;
if (!TextUtils.isEmpty(url)) {
mVideoView.setVideoPath(url);
}
}
public void openVideo(View View) {
mVideoView.setVideoPath(path);
}
}
但是运行它之后,它只运行了很少的时间(这只给了我第一个视频帧[固定的照片]),然后应用崩溃了,并且给我的应用没有响应消息而没有在日志中打印任何错误消息：

然后在日志中,我收到以下消息：
08-03 15:45:37.744: W/ActivityManager(852): Force finishing activity io.vov.vitamio.demo/.VideoViewDemo

解决方法:
扫描了很多near similar problems后,我发现这可能是因为它要求具有ACCESS_NETWORK_STATE权限,尽管日志没有告诉我,但是因为它告诉我执行此过程不是合格用户,因此该用户必须拥有获得资格的权限,因此,我添加了此权限：
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
因此,要使用Vitamio运行授权的RTSP实时流,您需要注册以下所有权限：
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
