Dynamic voltage/frequency scaling for video processing using embedded complexity metrics
A video decoder performs a method of dynamic voltage/frequency scaling (DVFS) for video processing. The method includes parsing a bitstream associated with a video to determine embedded information associated with a complexity of a first portion of the video, estimating the complexity of the first portion of the video using the embedded information, determining a voltage and frequency to be used for decoding the first portion of the video based on the estimated complexity, and decoding the first portion of the video at the determined voltage and frequency.
