I try to play a live stream on my android phone using the MediaPlayer
object. But I definitely see a black screen. Does anybody have any
experience with streaming on Android ?
Here is what I'm doing:
I broadcast a stream with Darwin streaming server (via
PlaylistBroadcast) to my Android phone. The stream is sent over RTP to
the IP of my device (unicast). A .sdp file describes my stream.
In my app, I try to play the stream with the following code where url
is "rtsp://server_ip/live.sdp"
private void playVideo(String url) {
try {
//media.setEnabled(false);
if (player==null) {
//System.out.println("create MediaPlayer");
player=new MediaPlayer();
player.setScreenOnWhilePlaying(true);
} else {
player.stop();
player.reset();
}
player.setDataSource(url);
//holder.setFixedSize(320, 240);
player.setDisplay(holder);
player.setAudioStreamType(AudioManager.STREAM_MUSIC);
player.setOnPreparedListener(this);
player.prepareAsync();
player.setOnBufferingUpdateListener(this);
player.setOnCompletionListener(this);
} catch (Throwable t) {
System.out.println("Exception in media prep: "+t.toString());
}
}
public void onPrepared(MediaPlayer mp) {
//System.out.println("onPrepared");
int width=player.getVideoWidth();
int height=player.getVideoHeight();
if (width!=0 && height!=0) {
holder.setFixedSize(width, height);
player.start();
}
}
I always have a black screen, buffering remains at 0%.
I checked that I can play this live stream on VLC and QT on a desktop,
and it works fine. If I request the same file via a direct RTSP
request (rtsp://server_IP/myVideo.mp4) the file plays correctly on my
android phone.
I also tried to request the .sdp file by an HTTP request (http://
server_IP/live.sdp) but the result is the same (black screen).
Does anybody have already succeeded in playing a live stream on an
android phone ?
Cheers
Jean
