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 = "Geeksforneveropen" # 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
