Popen without calling close() or terminate()

[chlee1016]

Hi team!
Thanks to your contributions, I am planning to use this videohash package in production with multiprocessing for bulk inference.
However, I found that the subprocesses opened from calling subprocess.Popen do not calling any close() or terminate() for the processes. (It can cause process leak as I think.)

Am I missing something similar method for close() in the code?
