摘要： Some implementations can compress a digital image to create a compressed image corresponding to the digital image. The digital image can be divided into a plurality of coding units and a determination can be made whether to divide each coding unit of the plurality of coding units into smaller coding units/prediction units based on (i) a range of pixel values in each coding unit and/or (ii) a number of bits to encode the coding unit. Rate distortion optimization can be performed based on a size of each of the prediction units. A determination can be made whether to perform a transform for each of the transform units based on a size of each prediction unit and/or a spatial frequency measure associated with each transform unit.

摘要： Disclosed herein are exemplary embodiments of innovations in the area of encoding pictures or portions of pictures (e.g., slices, coding tree units, or coding units) and determining whether and how certain filtering operation should be performed and flagged for performance by the decoder in the bitstream. In particular examples, various implementations for setting the sample adaptive offset (SAO) syntax elements in the H.265/HEVC standard are disclosed. Although these examples concern the H.265/HEVC standard and its SAO filter, the disclosed technology is more widely applicable to other video codecs that involve filtering operations (particularly multi-stage filtering operations) as part of their encoding and decoding processes.

摘要： Innovations in encoder-side decisions for coding of screen content video or other video can speed up encoding in various ways. For example, some of the innovations relate to ways to speed up motion estimation by identifying appropriate starting points for the motion estimation in different reference pictures. Many of the encoder-side decisions speed up encoding by terminating encoding for a block or skipping the evaluation of certain modes or options when a condition is satisfied. For example, some of the innovations relate to ways to speed up encoding when hash-based block matching is used. Still other innovations relate to ways to identify when certain intra-picture prediction modes should or should not be evaluated during encoding. Other innovations relate to other aspects of encoding.

摘要： Non-transform blocks of video content may be coded by selectively changing a scanning order. In some implementations, an encoder or decoder may perform a scanning process on a block according to a scanning order. When the block has not been transformed, the encoder or decoder may selectively change the scanning order to a different order. For example, if the block is associated with a particular type of prediction, the scanning order may be changed to a different order. In another example, if the non-transform block has a size that is smaller than a predetermined size, the scanning order may be changed to a different order.

摘要： Approaches to robust encoding and decoding of escape-coded pixels in a palette mode are described. For example, sample values of escape-coded pixels in palette mode are encoded/decoded using a binarization process that depends on a constant value of quantization parameter ("QP") for the sample values. Or, as another example, sample values of escape-coded pixels in palette mode are encoded/decoded using a binarization process that depends on sample depth for the sample values. Or, as still another example, sample values of escape-coded pixels in palette mode are encoded/decoding using a binarization process that depends on some other fixed rule. In example implementations, these approaches avoid dependencies on unit-level QP values when parsing the sample values of escape-coded pixels, which can make encoding/decoding more robust to data loss.
摘要翻译：描述了在调色板模式下对转义编码像素进行鲁棒编码和解码的方法。例如，调色板模式中的转义编码像素的采样值使用取决于样本值的量化参数（“QP”）的常数值的二值化处理进行编码/解码。或者，作为另一示例，调色板模式中的转义编码像素的样本值使用取决于样本值的样本深度的二值化处理进行编码/解码。或者，作为另一示例，调色板模式中的转义编码像素的采样值使用依赖于某些其他固定规则的二值化处理进行编码/解码。在示例实现中，当解析转义编码像素的采样值时，这些方法避免了对单位级QP值的依赖性，这可以使编码/解码对数据丢失更加鲁棒。

摘要： Various innovations in media encoding are presented herein. In particular, the innovations can reduce the computational complexity of encoding by selectively skipping certain evaluation stages during encoding. For example, based on analysis of decisions made earlier in encoding or based on analysis of media to be encoded, an encoder can selectively skip evaluation of certain coding tools (such as residual coding or rate-distortion-optimized quantization), skip evaluation of certain values for parameters or settings (such as candidate unit sizes or transform sizes, or candidate partition patterns for motion compensation), and/or skip evaluation of certain coding modes (such as frequency transform skip mode) that are not expected to improve rate-distortion performance during encoding.
摘要翻译：本文介绍了媒体编码的各种创新。特别地，创新可以通过在编码期间选择性地跳过某些评估阶段来降低编码的计算复杂度。例如，基于对编码方面的决策分析或基于要编码的媒体的分析，编码器可以有选择地跳过某些编码工具的评估（例如残差编码或速率失真优化量化），跳过某些用于参数或设置的值（例如候选单元大小或变换大小，或用于运动补偿的候选分区模式），和/或跳过不期望提高速率失真的某些编码模式（例如频率变换跳过模式）的评估编码期间的性能。
