Sure, I was thinking following (I have not implemented this myself mind):

<code>
MediaPlayer player;
Timer timer = new Timer();
//initialisation of the player

timer.schedule( new TimerTask() {
run() {
player.start();
}
}, 0, 200);

timer.schedule( new TimerTask() {
run() {
player.pause();
}
}, 100, 200);

</code>

You schedule 2 recurring tasks on a Timer: one to resume/start the
video every 200 milliseconds, and the second to pause it also every
200 milliseconds, with 100 millisecond offset. This should slow the
playback by the factor of 2. You can adjust the numbers to get
different ratios and I would not play or pause for longer than say 500
milliseconds, as it will look jerky.

It is possible that both timers will diverge (no real-time promise),
in which case you will have to do something a bit more clever than
arbitrary numbers, as the paused_time / play_time ratio will shift.

You will probably need to monitor actual track progress by using
MediaPlayer.getCurrentPosition(), rather than the inaccurate wall
clock.
