This is to facilitate investigation of cases where video capture / cameras do not seem to produce any frames.
There are several places in the video capture stack where frames might get dropped without raising any error event. In theory this could lead to the camera starting correctly, but then no frames ever getting delivered.
By adding this type of logging, we gain the ability to see if and where frames get dropped by Chromium or if frames are actually never delivered by the camera driver.
