Began implementing Quicktime for Java (QT4J) option in QD. As it is, Mac OS goes to Quicktime, while Windows goes to JMF. QT player stills needs some work.

+After pause the MPEG video and playing it again it gets faster

+
+
+The problem is in the setting the Media time.
+
+The safety way is to always set new media time with the
+following method: setMediaTime(Time time); .... if you want to
+use it after
+-player.stop(); used as real stop you can use setMediaTime(new
+Time(0.0));
+-player.stop(); used as real pause you have to use the
+combination:
+player.stop();
+Time currentTime = player.getMediaTime();
+//........
+player.setMediaTime(currentTime);
+player.start();
+

+
+
+I found a solution for this problem for those that are interested.
+
+what you have to do is store the time just before you pause and then set the
+time just before you play. here is a copy of my pause and play methods
+
+// Start the player
+private void play() {
+if (player != null)
+{
+if (pauseTime != null)
+{
+player.setMediaTime(pauseTime);
+}
+if (player.getTargetState() < Player.Started)
+player.prefetch();
+player.start();
+}
+}
+
+// Pause the player
+private void pause() {
+if (player != null)
+pauseTime = player.getMediaTime();
+player.stop();
+}
+
+
+that should solve your pause play problems!
+
+> The problem is below. It seems quite a few people are
+> having this problem but i have not seen a solution
+> around. I really need a solution to this problem as
+> the whole point of my application is that it plays
+> divx and mpeg videos. At the moment i have divx
+> movies playing through the mpeg demuxer as the avi one
+> stuffed up the audio. I think that is the reason it
+> affects both divx and mpeg. My application is due in
+> one week and my client is not going to be very happy
+> if this problem happens every time they pause then
+> play the video.
+> The player is for divx movies. If anyone knows how to
+> solve this problem or how to make it so you can pause
+> and resume divx movies please respond.
+>
+> Pause and Resume playback.
+> The video plays at a high rate and there is no audio.
+> Problem doesn't appear while seeking.
