Hi,
I want to obtain details about the protocol RTP using android.net.rtp but
when I call any RtpStream class'methods the programm doesn´t work. Here is
the code:
public class MainActivity extends Activity {
private static final String TAG = "MainActivity";
public VideoView mVideoView;
public EditText mPath;
private ImageButton mPlay;
private ImageButton mPause;
private ImageButton mReset;
private ImageButton mStop;
public String current;
public RtpStream mRtpStream ;
private String text;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mVideoView = (VideoView) findViewById(R.id.surface_view);
mPath = (EditText) findViewById(R.id.edit_message);
text= "rtsp://192.168.1.37/sample_300kbit.mp4";
mPath.setText(text);
mPlay = (ImageButton) findViewById(R.id.play);
mPause = (ImageButton) findViewById(R.id.pause);
mReset = (ImageButton) findViewById(R.id.reset);
mStop = (ImageButton) findViewById(R.id.stop);
mPlay.setOnClickListener(new OnClickListener() {
public void onClick(View view) {
reproducirVideo();
}
});
mPause.setOnClickListener(new OnClickListener() {
public void onClick(View view) {
if (mVideoView != null) {
mVideoView.pause();
}
}
});
mReset.setOnClickListener(new OnClickListener() {
public void onClick(View view) {
if (mVideoView != null) {
mVideoView.seekTo(0);
}
}
});
mStop.setOnClickListener(new OnClickListener() {
public void onClick(View view) {
if (mVideoView != null) {
current = null;
mVideoView.stopPlayback();
}
}
});
runOnUiThread(new Runnable(){
public void run() {
reproducirVideo();
}
});
}
public void reproducirVideo() {
try {
final String path = mPath.getText().toString();
Log.v(TAG, "path: " + path);
if (path == null || path.length() == 0) {
Toast.makeText(MainActivity.this, "Campo URL vacío",
Toast.LENGTH_LONG).show();
} else {
if (path.equals(current) && mVideoView != null) {
mVideoView.start();
mVideoView.requestFocus();
return;
}
current = path;
mVideoView.setVideoPath(getDataSource(path));
mVideoView.start();
mVideoView.requestFocus();
TextView texto= (TextView) findViewById(R.id.mensaje);
InetAddress address = null;
mRtpStream.associate(InetAddress.getByAddress(new byte[] {(byte)192,
(byte)168, (byte)1, (byte)37 }), 1220);
address=mRtpStream.getRemoteAddress();
String address_string = address.getHostAddress();
texto.setText(" La dirección local es "+(address_string)+" ");
}
} catch (Exception e) {
Log.e(TAG, "error: " + e.getMessage(), e);
if (mVideoView != null) {
mVideoView.stopPlayback();
}
}
}
private String getDataSource(String path) throws IOException {
if (!URLUtil.isNetworkUrl(path)) {
return path;
} else {
URL url = new URL(path);
URLConnection cn = url.openConnection();
cn.connect();
InputStream stream = cn.getInputStream();
if (stream == null)
throw new RuntimeException("stream is null");
File temp = File.createTempFile("mediaplayertmp", "dat");
temp.deleteOnExit();
String tempPath = temp.getAbsolutePath();
FileOutputStream out = new FileOutputStream(temp);
byte buf[] = new byte[128];
do {
int numread = stream.read(buf);
if (numread <= 0)
break;
out.write(buf, 0, numread);
} while (true);
try {
stream.close();
} catch (IOException ex) {
Log.e(TAG, "error: " + ex.getMessage(), ex);
}
return tempPath;
}
}
}
