对于mp4文件，目前已测试在Windows10上设置后支持显示的的详细信息有：标题（`title`）、备注（`comment`）、流派（`genre`）、作曲者（`composer`）

如需查看更多的详细信息，可以参考本文自己进行编写Python代码来查看。  
如需编程批量设置视频文件的详细信息，可以参考：[使用FFmpeg设置视频文件的详细信息][FFmpeg]

# 2. 代码 #

安装pymediainfo可以参考：[Python3安装pymediainfo][Python3_pymediainfo]

from pymediainfo import MediaInfo
    from moviepy.editor import VideoFileClip
    
    media_info = MediaInfo.parse('t2.mp4')
    
    data = media_info.to_json()
    print(data)

# 3. 输出结果 #

注意：详细信息只有不为空的时候才能找到，如标题（`title`）为空，则无法找到`title`这个键。
