1. A method, comprising:
receiving control information associated with a prediction unit of a video frame at a node of a video encoding pipeline used to compress the video frame, wherein the control information comprises a skip bit indicating a predicted skip decision that the prediction unit is not skipped;
making an actual skip decision for the prediction unit by analyzing transform units comprising the prediction unit, wherein the actual skip decision indicates whether the prediction unit is skipped during encoding; and
providing the actual skip decision for the prediction unit to a downstream node of the video encoding pipeline.
