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
Python3 1==
Output :

# 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
# 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()
