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
# importing pyglet module import pyglet # width of window width = 800 # height of window height = 500 # caption i.e title of the window title = "Geeksforneveropen" # 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() |
