PYGLET——媒体播放器

在本文中，我们将看到如何在Python中的 PYGLET 模块中创建一个简单的媒体播放器。 Pyglet 是一个易于使用但功能强大的库，用于开发视觉丰富的 GUI 应用程序，如游戏、多媒体等。窗口是占用操作系统资源的“重量级”对象。 Windows 可能显示为浮动区域，也可以设置为填充整个屏幕（全屏）。为了加载文件，即资源，我们使用 pyglet 的资源模块。该模块允许应用程序指定资源的搜索路径。 Pyglet 可以播放 WAV 文件，如果安装了 FFmpeg，还有很多其他的音频和视频格式。播放由 Player 类处理，该类从 Source 对象读取原始数据并提供暂停、搜索、调整音量等方法。 Player 类实现了最好的可用音频设备。
我们可以在下面给出的命令的帮助下创建一个窗口和播放器对象

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

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

In order to play a media in pyglet we have to do the following
1. Create pyglet window
2. Create a player object
3. Load the media by player from the path of media
4. Add loaded media in the queue of player
5. Play the video
6. Create a key press event handler which is used to pause and resume the video

编程需要懂一点英语

下面是实现

Python3

# importing pyglet module
import pyglet
 
# width of window
width = 500
   
# 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 ="media.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():
     
    # 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:
         
        # printing the message
        print("Key : P is pressed")
         
        # pause the video
        player.pause()
         
        # printing message
        print("Video is paused")
         
         
    # key "r" get press
    if symbol == pyglet.window.key.R:
         
        # printing the message
        print("Key : R is pressed")
         
        # resume the video
        player.play()
         
        # printing message
        print("Video is resumed")
 
# run the pyglet application
pyglet.app.run()

输出：

Key : P is pressed
Video is paused
Key : R is pressed
Video is resumed
Key : P is pressed
Video is paused
Key : R is pressed
Video is resumed
