Can't move the agent using vc.play(vc.MoveAhead()) in VideoController

When I using VideoController with the given demo, the agent doesn't move at all. I didn't change anything, if anyone is in the same situation as me？

from ai2thor.video_controller import VideoController
with VideoController() as vc:
    vc.play(vc.MoveAhead())
    vc.wait(5)
    vc.play(vc.MoveAhead())
    vc.export_video('thor.mp4')

Also, there is something wrong with vc.play(vc.RotateRight), I add two missing variable and it can work now. But I don't know why use TeleportFull instead of RotationRight in _rotate?

According to my test, vc.play(vc.MoveAhead()) only work when about $\frac{moveMagnitude}{frames}<\frac{1}{15}$, still don't know why
