Sets the audio/video playback speed.
The parameter, val, is optional. It's a number that sets the playback speed. 1 plays the media at normal speed, 0.5 plays it at half speed, 2 plays it at double speed, and so on. -1 plays the media at normal speed in reverse.
Calling media.speed() returns the current speed as a number.
Note: Not all browsers support backward playback. Even if they do, playback might not be smooth.
