Python VLC MediaPlayer – 获取 FPS

在本文中，我们将看到如何在Python vlc 模块的 MediaPlayer 对象中获取 fps 即帧速率。 VLC媒体播放器是VideoLAN项目开发的一款免费开源的便携式跨平台媒体播放软件和流媒体服务器。 MediPlyer 对象是 vlc 模块中用于播放视频的基本对象。我们可以借助MediaPlayer方法创建一个 MediaPlayer 对象。帧速率是称为帧的连续图像出现在显示器上的频率。该术语同样适用于电影和摄像机、计算机图形和动作捕捉系统。帧率也可以称为帧频，以赫兹表示。

In order to do this we will use get_fps method with the MediaPlayer object

Syntax : media_player.get_fps()

Argument : It takes no argument

Return : It returns float

编程需要懂一点英语

下面是实现

# importing vlc module
import vlc
  
# importing time module
import time
  
  
# creating vlc media player object
media_player = vlc.MediaPlayer()
  
# media resource locator
mrl = "death_note.mkv"
  
# setting mrl to the media player
media_player.set_mrl(mrl)
  
# start playing video
media_player.play()
  
# wait so the video can be played for 5 seconds
# irrespective for length of video
time.sleep(5)
  
# getting fps
value = media_player.get_fps()
  
# printing fps
print("Frame Rate per Second : ")
print(value)

输出：

Frame Rate per Second : 
23.976215362548828

另一个例子
下面是实现

# importing vlc module
import vlc
  
# importing time module
import time
  
# creating vlc media player object
media_player = vlc.MediaPlayer()
  
# media resource locator
mrl = "1.mp4"
  
# setting mrl to the media player
media_player.set_mrl(mrl)
  
# start playing video
media_player.play()
  
# wait so the video can be played for 5 seconds
# irrespective for length of video
time.sleep(5)
  
  
# getting cursor co-ordinates
value = media_player.video_get_cursor()
  
# getting fps
value = media_player.get_fps()
  
# printing fps
print("Frame Rate per Second : ")
print(value)

输出：

Frame Rate per Second : 
29.969999313354492
