play mp3 in a position

[felixksp]

Hi all,

I would like to play a mp3 file, starting the playing from a time. I need it to simulate a pause in a mp3 player. I have found in other posts that can be used setMediaTime, but the following error appears:

javax.microedition.media.MediaException: Could not set time: -5

I am using a Nokia N91, so it is a good device in which there shouldn't be problems with that.

If anyone knows other way to simulate a pause, I would be happy

Regards,

You can simply pause a thread in which your player is living. After N seconds of sleep thread will start playing your mp3 file:

player.prefetch(); // make player ready to play data

thread.sleep(5000L); // try to sleep for 5 seconds

player.start(); // play media

Not all MMAPI implementations are allowing to set the media time, but using a sleeping thread you'll be able to emulate it virtually on all mobile platforms.

But, once the player has been started, I can't pause the thread..., my code is the following...

public void run()
{
MSTrack currTrack = null;
boolean errorPlaying = true;
synchronized (localLockObj)
{
while (errorPlaying)
{
try
{
if(!bIsStreaming)
{
Logger.debug("MSPlayerThread.run: Entry");

System.gc();

// TODO: will need updated when we play a clip
currTrack = (MSTrack) tracksToPlay.elementAt(currentTrackIdx);
Logger.debug("MSPlayerThread.run: [" + currTrack.localURI + "]");

// create player for current track

Logger.debug("MSPlayerThread.run: Creating player");

fileConn = (FileConnection) Connector.open(currTrack.localURI);
player = Manager.createPlayer(fileConn.getURL());
player.addPlayerListener(this);

player.realize();

//set volume
VolumeControl vc = (VolumeControl) player.getControl("VolumeControl");
if(vc != null)
vc.setLevel(VolumeLevel);

player.setLoopCount(1);

/*
if(mediaTime > 0)
player.setMediaTime(mediaTime);
*/

player.start();

// we're playing if we get here, so set our local state vars
playing = true;
isPaused = false;
errorPlaying = false;

isInStreaming = false;

localPlayStartTime = new Date().getTime();
localTrack = (MSTrack) tracksToPlay.elementAt(currentTrackIdx);

// send playing event
Logger.debug("MSPlayerThread.playerUpdate: sending 'playing' event");
MyStrandsMIDlet.midlet.communicator.userTrackPlaying(localTrack);


MyStrandsMIDlet.midlet.get_currentTrackTicker().setString(currTrack.name + " (" + currTrack.artistName + ")");
}
else
{
try
{
//OS streaming link
//Player player = Manager.createPlayer(
// "rtsp://a1176.v128388.c12838.g.vr.akamaistream.net/ondemand/7/1176/12838/v40614/muze.download.akamai.com/2890/us/usrm/320/277320_1_13.rm"
// );

System.gc();

Logger.debug("Va a hacer streaming de : " + strRMClipURI);
player = Manager.createPlayer(strRMClipURI);
player.addPlayerListener(this);
//player = Manager.createPlayer("rtsp://a1176.v128388.c12838.g.vr.akamaistream.net/ondemand/7/1176/12838/v40614/muze.download.akamai.com/2890/us/usrm/320/277320_1_13.rm");
player.prefetch();
player.start();
player.realize();

// get volume control for player and set volume to max
VolumeControl vc = (VolumeControl)player.getControl("VolumeControl");
if ( vc != null )
vc.setLevel(VolumeLevel);



playing = true;
isPaused = false;
errorPlaying = false;
}
catch (Exception e)
{
isInStreaming = false;
MyStrandsMIDlet.showError(LocalizationSupport.getMessage("Streaming_failed!") );
Logger.debug(e.toString());
}
}
}
catch (MediaException e) {
Logger.error("MSPlayerThread.run: ME [" + currTrack.localURI + "]",
e);
destroy();
}
catch (SecurityException e) {
Logger.error("MSPlayerThread.run: SE [" + currTrack.localURI + "]",
e);
destroy();
}
catch (IOException e) {
Logger.error(
"MSPlayerThread.run: IOE [" + currTrack.localURI + "]", e);
destroy();
}
catch (Exception e) {
Logger.error("MSPlayerThread.run: E [" + currTrack.localURI + "]",
e);
destroy();
}
catch (Throwable t) {
Logger.error("MSPlayerThread.run: Throwable", t);
destroy();
}
}

For more info, in other thread have commented to me that if you sleep the thread, the Player will not pause, because internally MMA has its own threads..., which is logical on the other hand.
