0.11.x upgrade to 0.12.x

[whi-sper]

Describe the bug Run command cannot be terminated， command ['-i', '/resource/TearsOfSteel.mp4', '-vf', 'fps=30', '-q:v', '2', '-s', '1280x534', '/frame/TearsOfSteel/pic-%d.jpg']

log:

Expected behavior I want to read the frames of the imported video, and then play the images in the canvas, but the frame reading does not seem to be terminated. It works well in the original 0.11.x version
