python解决b 视频加密

代码很简单：

 1 import sys                                                               
 2 from pathlib import Path
 3 from numpy import fromfile, uint8   # pip install numpy
 4 
 5 rootDir = Path(sys.argv[0]).resolve().parent  # 脚本文件的父文件夹的绝对路径 6 
 7 for f in rootDir.rglob("**/*.mp4"):
 8     read = fromfile(f, dtype=uint8)
 9     if all(read[0:3] == [255, 255, 255]):
10         outfile = f"{str(f.name)}"
11         read[3:].tofile(rootDir / outfile)
12         print(outfile)

使用也很简单，将该程序放到需要转换的文件的目录，执行python fileName.py，这里假设你的文件名为fileName，如果不同，请自行修改。

最后，还需要重命名文件：
