Audio and video playback.
pyglet can play WAV files, and if AVbin is installed, many other audio and video formats.
Playback is handled by the Player class, which reads raw data from Source objects and provides methods for pausing, seeking, adjusting the volume, and so on. The Player class implements the best available audio device (currently, only OpenAL is supported):
player = Player()
A Source is used to decode arbitrary audio and video files. It is associated with a single player by “queuing” it:
source = load('background_music.mp3') player.queue(source)
Use the Player to control playback.
If the source contains video, the Source.video_format attribute will be non-None, and the Player.texture attribute will contain the current video image synchronised to the audio.
Decoding sounds can be processor-intensive and may introduce latency, particularly for short sounds that must be played quickly, such as bullets or explosions. You can force such sounds to be decoded and retained in memory rather than streamed from disk by wrapping the source in a StaticSource:
bullet_sound = StaticSource(load('bullet.wav'))
The other advantage of a StaticSource is that it can be queued on any number of players, and so played many times simultaneously.
pyglet relies on Python’s garbage collector to release resources when a player has finished playing a source. In this way some operations that could affect the application performance can be delayed.
The player provides a Player.delete() method that can be used to release resources immediately. Also an explicit call to `gc.collect()`can be used to collect unused resources.

bool(x) -> bool
Returns True when the argument x is true, False otherwise. The builtins True and False are the only two instances of the class bool. The class bool is a subclass of the class int, and cannot be subclassed.
The singleton AbstractListener object.
Deprecated. Use AbstractAudioDriver.get_listener
