I have a GLib-GObject-ERROR when I read two videos

[ccarpentier]

Hello,

I am using VLC0.9.8a (vlc-0.9.8a-1.el5.rf.i386.rpm) with JVLC0.9.0 (jvlc-core-0.9.0-SNAPSHOT-20080727).
To launch my application, I added the following argument in VM: -Djna.library.path=/usr/lib
I use the following API of JVLC to synchronize two videos and an audio with the method "MediaPlayer.setTime(...)":
org.videolan.jvlc.JVLC
org.videolan.jvlc.MediaDescriptor
org.videolan.jvlc.MediaPlayer
org.videolan.jvlc.event.MediaPlayerListener

In my application, when I read only one video, it is OK.
However, when I read two videos in same time (in creating two instances of JVLC), I have some problems...
My traces are:

My sources (some parts):
JVLC jVLC = new JVLC();

MediaDescriptor mediaDescriptor = new MediaDescriptor(jvlc, "file://" + file.getAbsolutePath());
MediaPlayer mediaPlayer = mediaDescriptor.getMediaPlayer();

mediaPlayer.addListener(new InternalReplayerListener());;
if (canvas != null) {
jVLC.setVideoOutput(canvas);
}
Can you provide me a new version of JVLC?
// To play a video or an audio
if (mediaPlayer != null) {
mediaPlayer.play();
try {
for (; !mediaPlayer.willPlay(); Thread.sleep(100L)) {
System.out.println("Will Play : " + mediaPlayer.willPlay());
}
}
catch(InterruptedException ie) {
}
mediaPlayer.setTime(position);
}


// To pause a video or an audio
if (mediaPlayer != null) {
mediaPlayer.pause();
}

// To stop a video or an audio
if (mediaPlayer != null) {
MediaDescriptor mediaDescriptor = mediaPlayer.getMediaDescriptor();
mediaPlayer.stop();

mediaDescriptor.release();
mediaPlayer = null;
if (jVLC != null) {
jVLC.release();
jVLC = null;
}
}

Can you help me ?

Thanks.

VLC does not use glib, and of course not gobject. This is something else.
