PYGLET – Step to Next Frame in Player

In this article, we will see how we can step up next frame in media 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. The Player class implements the best available audio device. Stepping forwards one video frame in the current source means that next frame in queue get displayed.

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()

In order to do this we use seek_next_frame play method with the player object
Syntax : player.seek_next_frame()
Argument : It takes no argument
Return : It returns None

Below is the implementation

Python3

# 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) 


# video path
vidPath ="gfg.mp4"

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

# 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():
    
    # clear 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")
        
    
    # when key "f" get pressed
    # for seeking next frame
    if symbol == pyglet.window.key.F:
        
        # seek next frame
        player.seek_next_frame()
        
        # printing message
        print("Seeking Next Frame")
        
# seek video at time stamp = 4
player.seek(4)

# pause the video
player.pause()
        
        

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

Output :

Seeking Next Frame
