    Abstract: A method includes receiving a video bitstream and a flag and interpreting the flag to determine a transform that was used at an encoder. The method also includes, upon a determination that the transform that was used at the encoder includes a secondary transform, applying an inverse secondary transform to the received video bitstream, where the inverse secondary transform corresponds to the secondary transform used at the encoder. The method further includes applying an inverse discrete cosine transform (DCT) to the video bitstream after applying the inverse secondary transform.

    Abstract: 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.

    Abstract: A method includes calculating a complexity value for each segment or version of multimedia content. The multimedia content has multiple versions associated with common content and different encoding parameters, and each version is divided into segments. The method also includes adaptively streaming the multimedia content to a client device based on at least some of the calculated complexity values. The complexity value for each segment or version is calculated by summing multiple operation complexity values defining complexities of operations for decoding the segment or version. The operation complexity values could include values for a bit parsing operation, a buffer initialization operation, an intra-prediction operation, an inverse quantization and transform operation, a reference block fetch operation, a fractional interpolation operation, and in-loop deblocking operation, a sample adaptive offset correction operation, an adaptive loop filtering operation, and a de-ringing filtering operation.
