  • Publication number: 20230027742
    Abstract: This disclosure describes systems, methods, and devices related to complexity aware encoding. A device may generate a list of encodes based on pairs of resolution and quantization parameters (QP) pairs associated with one or more video segments received from a source. The device may generate an estimated bit rate associated with the one or more video segments based on an analysis of the one or more video segments. The device may determine distortion values associated with the one or more video segments. The device may apply a weighting mechanism to the distortion values using the estimated bit rate. The device may select a subset of encodes based on the weighting mechanism. The device may perform the subset of encodes on the one or more video segments for transmission.

  • Publication number: 20230010681
    Abstract: This disclosure describes systems, methods, and devices related to bit-rate-based hybrid encoding. A device may generate a list of encodes based on pairs of resolution and quantization parameters (QP) pairs associated with one or more video segments received from a source. The device may generate an estimated bit rate associated with the one or more video segments based on an analysis of the one or more video segments. The device may compare the estimated bit rate to a threshold. The device may switch between a software encoder and a hardware encoder based on the comparison of the estimated bit rate to the threshold. The device may encode each of the one or more video segments for transmission using the hardware encoder or the software encoder.

  • Patent number: 11095895
    Abstract: Techniques related to transform coefficient shaping for video encoding are discussed. Such techniques include applying weighting parameters from one or more perceptually-designed matrices of weighting parameters to blocks of transform coefficients to generate weighted transform coefficients and encoding the weighted transform coefficients into a bitstream. The process may be based on sets of perceptually designed matrices of weighting parameters. Classifier outputs may be used to select from the set of perceptually designed matrices a subset of matrices to work with. The latter may be used in a synthesis procedure to develop the final weighting matrix to be used is shaping the transform coefficients.

  • Patent number: 10904552
    Abstract: Techniques related to video encoding are discussed that, for each block of input video, select an individual partitioning and coding mode selection technique from multiple such selection techniques. For a picture, the selection algorithm takes as input scores for individual blocks, costs of the various partitioning and coding mode selection techniques, and various detector outputs. The selection algorithm provides as output a partitioning and coding mode selection technique for each block in picture. The algorithms selection is such that the overall cost of the selected algorithms in the picture is as close as possible to a given picture budget. Furthermore, a partitioning and coding mode selection algorithms, binary depth partitioning (BDP), is discussed. For a block, BDP provides fast convergence to a partitioning and associated coding modes first evaluating intermediate partitioning options and converging on the final partitioning by evaluating either larger of smaller partitions.

  • Patent number: 10687054
    Abstract: Techniques related to video encoding that provide for a decoupled prediction and coding structure for improved performance are discussed. Such techniques include determining final partitioning decisions for blocks of a picture by evaluating intra modes for candidate partitions by comparing the candidate partitions to intra predicted partitions generated using only original pixel samples and evaluating inter modes for the candidate partitions by comparing the candidate partitions to search partitions including original pixel samples and encoding using the final partitioning decision.

  • Publication number: 20190045198
    Abstract: Techniques related to detection of features and modification of encoding based on such detected features for improved data utilization efficiency are discussed. Such techniques include generating a partitioning decision for a block and coding mode decisions for partitions of the individual block using the detected features or indicators thereof based on one or more of generating a luma and chroma or luma only evaluation decision for a partition, generating a merge or skip mode decision for a partition having an initial merge mode decision, generating only a portion of a transform coefficient block for a partition, and evaluating 4×4 partitions only for any partition of the partitions that are 8×8 initial coding partitions.
