Subject: [PATCH] fix(control): advance video frames via cap, not the
 always-None video var

The VideoCapture is stored in cap, but the per-frame read and skip/yield guards referenced video, which is set to None at function entry and never reassigned. As a result only the first frame of a video input was processed.
