PYGLET – Current Source Ran-out event of Player

Last Updated : 18 Oct, 2021

In this article we will see how we can trigger the current source ran-out event of player of PYGLET module in python. Pyglet is easy to use but powerful library for developing visually rich GUI applications like games, multimedia etc. A window is a "heavyweight" object occupying operating system resources. Windows may appear as floating regions or can be set to fill an entire screen (fullscreen). This module allows applications to specify a search path for resources. Pyglet can play WAV files, and if FFmpeg 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. This event get triggered when the current source ran out of data. The default behaviour is to advance to the next source in the playlist if the loop attribute is set to False. If loop attribute is set to True, the current source will start to play again until next_source() is called or loop is set to False. We can create a window and player object with the help of commands given below

# creating a window
window = pyglet.window.Window(width, height, title)

# creating a player for media
player = pyglet.media.Player()

Below is the syntax of the event

# end of source event
@window.event
def on_eos():
    # printing some message
    print("Current Source ended")

Below is the implementation

Python3 1==

# importing pyglet module
import pyglet

# width of window 
width = 800
  
# height of window 
height = 500
  
# caption i.e title of the window 
title = "Geeksforgeeks"
  
# creating a window 
window = pyglet.window.Window(width, height, title) 


# creating a media player object
player = pyglet.media.Player()

# loading a new media
media = pyglet.media.load("media.mp4")


# video path
vidPath ="gfg.mp4"

# add this media in the queue
player.queue(media)

# creating a source object
source = pyglet.media.StreamingSource()

# load the media from the source
MediaLoad = pyglet.media.load(vidPath)

# add this media in the queue
player.queue(MediaLoad)



# play the video
player.play()


# on draw event
@window.event
def on_draw():
    
    # clea the window
    window.clear()
    
    # if player source exist
    # and video format exist
    if player.source and player.source.video_format:
        
        # get the texture of video and
        # make surface to display on the screen
        player.get_texture().blit(0, 0)
        
        
# key press event     
@window.event 
def on_key_press(symbol, modifier): 
  
    # key "p" get press 
    if symbol == pyglet.window.key.P: 
        
        # pause the video
        player.pause()
        
        # printing message
        print("Video is paused")
        
        
    # key "r" get press 
    if symbol == pyglet.window.key.R: 
        
        # resume the video
        player.play()
        
        # printing message
        print("Video is resumed")
        
# end of source event
@window.event
def on_eos():
    # printing some message
    print("Current Source ended")
    

# run the pyglet application
pyglet.app.run()
