ffmepg

我想给manim提供检测ffmpeg的程序 `import subprocess

cmd = "ffmpeg -version" cmd_return = subprocess.getoutput(cmd) if cmd_return == "'ffmpeg' 不是内部或外部命令，也不是可运行的程序或批处理文件。": raise Exception("FFMPEG not found") else: print("found FFMPEG")`

I don't quite get this issue. What is the error/what do you want to change? Also could you try to use ASCII characters to describe it, because half of your issue doesn't even render, those characters aren't in my font.

Sometimes, ffmpeg is not installed, but manim can run, but video cannot be exported

ffmpeg is in the README under requirements, so I don't think that we need additionally check in the code if ffmpeg is installed.
