Abstract:
1. A method comprising: accessing a frame of a video, the accessed frame to be decoded based on zero or more other frames included in the video; accessing an intended prediction identifying the zero or more frames of the video upon which decoding of the accessed frame is based; accessing an actual prediction identifying the zero or more frames of the video upon which decoding of the accessed frame is based; comparing, by a decoder implemented using a processor, the intended prediction with the actual prediction; establishing, based on the comparing, whether the intended prediction matches the actual prediction; and determining by the decoder, based on the establishing, whether the intended and actual predictions identify a common set of frames; wherein the intended prediction identifying zero or more frames of the video comprises a predetermined sequence of dependency frames indicated by information associated with the accessed frame and the actual prediction identifying zero or more frames of the video comprises a queuing order of frames corresponding to the accessed frame.
