Python teaches you to convert short videos into Win10 dynamic desktop

The process of converting a short video into a dynamic desktop requires first converting the video into an animated gif image or webm video, and then using a third-party tool to set it as a dynamic desktop. The following is a code example that uses Python to convert a video to a webm video and set it as a dynamic desktop:

1. First, we need to install the two Python libraries opencv-python and moviepy, which are used to read video files and process videos respectively:

pip install opencv-python
pip install moviepy

2. Define video2webm()a function to implement the process of converting video to webm format and saving it:

import cv2
from moviepy.editor import VideoFileClip

def video2webm(video_path, webm_path):
    # 使用moviepy库读取视频文件
    clip = VideoFileClip(video_path)

    # 获取视频分辨率和帧数
    width, height = clip.size
    fps = clip.fps

    # 创建WebM视频编码器
    fourcc = cv2.VideoWriter_fourcc(*"VP80")
    writer = cv2.VideoWriter(webm_path, fourcc, fps, (width, height))

    # 逐帧将视频转换为WebM帧，并写入文件
    for frame in clip.iter_frames():
        frame_rgb = cv2.cvtColor(frame, cv2.COLOR_RGB2BGR)
        writer.write(frame_rgb)

    # 释放资源
    writer.release()

In the above code, we use the OpenCV library to read video files and convert videos into static pictures, use the moviepy library to read video files and obtain the resolution and number of frames of the video, and use the cv2 library to create a WebM video encoder. And use the iter_frames() method to read the video file frame by frame, use the cv2 library to convert each frame from RGB to BGR, write it to the WebM encoder, and finally release the resources. After the video conversion is completed, a .webm video file will be generated and saved to the specified path.

3. Define set_dynamic_wallpaper()a function to use WebM video as a dynamic desktop:

import os

def set_dynamic_wallpaper(video_path):
    # 设置WebM视频为Gnome 3桌面壁纸
    os.system(f"gsettings set org.gnome.desktop.background picture-uri file://{
      
      video_path}")

In the above code, we use the function of the os library to call the shell command, and use the gsettings command to use the WebM video as a dynamic desktop, that is, to set the current desktop background to the specified file path. Note: The above code can only set dynamic wallpaper in the Gnome 3 desktop environment.

4. Finally, we can combine the above two functions to realize the function of setting the specified video as a dynamic desktop:

def video2dynamic_wallpaper(video_path, webm_path):
    video2webm(video_path, webm_path)
    set_dynamic_wallpaper(webm_path)

In this function, the video2webm() function is first called to convert the video to WebM format, and then the set_dynamic_wallpaper() function is called to set the WebM video as the current desktop dynamic wallpaper.

Run video2dynamic_wallpaper()the function to set the specified video as a dynamic desktop. You can modify the corresponding code according to the specific environment and needs, improve the functions and apply it to the actual desktop environment.
