New submission from Xuan Hu <huxuan8218...@gmail.com>:
The original issue is that the `timeout` in `subprocess.run()` does not work properly, so I try to use `subprocess.Popen()` instead. There are two references I found, [1] is the implementation of `subprocess.run()` and [2] is the example for `Popen.communicate()`. Surprisingly, [2] works for me, and seems the `with` statement is the cause of the issue. I created a snippet [3] to reproduce the bug, note that `ffmpeg` is needed to run the script. Ideally, all the time should be less than 0.1 or just a little bit greater than 0.1, but when using the `with` statement, the result would be much larger than that.
