摘要： A processor that processes encoded media is configured so as to apply constraints to the encoded bitstream. Such constraints are not those required by a specification of a standard with which the encoded media is compliant; instead such constraints reflect portions of the standard that are insufficiently constrained and are applied by the processor to ensure that the processor does not experience performance degradation or errors. The constraints can be applied, for example, as a preprocessing step before reading, writing or decoding the bitstream, or while the bitstream is being decoded, or while the bitstream is being received from a transmission.

摘要： One or more techniques and/or systems are provided for video stabilization and/or for image frame generation. For example, a user may instruct a video application hosted on a smart phone to capture a video at a target resolution of 1080 pixels. A padded input having a padded resolution that is larger than the target resolution may be obtained from a capture device, such as a camera of the smart phone. The padded input may be provided to a video stabilization component to obtain a target image frame having the target resolution. In this way, the video stabilization component may perform cropping using padded margin pixels (e.g., additional pixels of the padded input beyond the 1080 pixels of the target resolution) so that image upscaling after cropping (e.g., to account for global warping, etc.) may be mitigated to reduce blur that may otherwise result from image upscaling.

摘要： Video frames of a higher-resolution chroma sampling format such as YUV 4:4:4 are packed into video frames of a lower-resolution chroma sampling format such as YUV 4:2:0 for purposes of video encoding. For example, sample values for a frame in YUV 4:4:4 format are packed into two frames in YUV 4:2:0 format. After decoding, the video frames of the lower-resolution chroma sampling format can be unpacked to reconstruct the video frames of the higher-resolution chroma sampling format. In this way, available encoders and decoders operating at the lower-resolution chroma sampling format can be used, while still retaining higher resolution chroma information. In example implementations, frames in YUV 4:4:4 format are packed into frames in YUV 4:2:0 format such that geometric correspondence is maintained between Y, U and V components for the frames in YUV 4:2:0 format.
摘要翻译：出于视频编码的目的，诸如YUV 4：4：4的更高分辨率色度采样格式的视频帧被打包成较低分辨率色度采样格式（例如YUV 4：2：0）的视频帧。例如，YUV 4：4：4格式的帧的采样值以YUV 4：2：0格式打包成两帧。在解码之后，可以解压缩较低分辨率色度采样格式的视频帧以重构较高分辨率色度采样格式的视频帧。以这种方式，可以使用以较低分辨率色度采样格式操作的可用编码器和解码器，同时仍然保留更高分辨率的色度信息。在示例实现中，YUV 4：4：4格式的帧以YUV 4：2：0格式打包成帧，使得在YUV 4：2：0格式的帧中的Y，U和V分量之间保持几何对应。

摘要： Innovations for category-prefixed data batching (“CPDB”) of entropy-coded data or other payload data for coded media data, as well as innovations for corresponding recovery of the entropy-coded data (or other payload data) formatted with CPDB. The CPDB can be used in conjunction with coding/decoding for video content, image content, audio content or another type of content. For example, after receiving coded media data in multiple categories from encoding units, a formatting tool formats payload data with CPDB, generating a batch prefix for a batch of the CPDB-formatted payload data. The batch prefix includes a category identifier and a data quantity indicator. The formatting tool outputs the CPDB-formatted payload data to a bitstream. At the decoder side, a formatting tool receives the CPDB-formatted payload data in a bitstream, recovers the payload data from the CPDB-formatted payload data, and outputs the payload data (e.g., to decoding units).

摘要： Innovations in signaling of reference picture list (“RPL”) modification information. For example, a video encoder evaluates a condition that depends at least in part on a variable indicating a number of total reference pictures. Depending on the results of the evaluation, the encoder signals in a bitstream a flag that indicates whether an RPL is modified according to syntax elements explicitly signaled in the bitstream. A video decoder evaluates the condition and, depending on results of the evaluation, parses from a bitstream a flag that indicates whether an RPL is modified according to syntax elements explicitly signaled in the bitstream. The condition can be evaluated as part of processing for an RPL modification structure that includes the flag, or as part of processing for a slice header. The encoder and decoder can also evaluate other conditions that affect syntax elements for list entries of the RPL modification information.

摘要： Innovations in control and use of chroma quantization parameter (“QP”) values that depend on luma QP values. More generally, the innovations relate to control and use of QP values for a secondary color component that depend on QP values for a primary color component. For example, during encoding, an encoder determines a QP index from a primary component QP and secondary component QP offset. The encoder maps the QP index to a secondary component QP, which has an extended range. The encoder outputs at least part of a bitstream including the encoded content. A corresponding decoder receives at least part of a bitstream including encoded content. During decoding, the decoder determines a QP index from a primary component QP and secondary component QP offset, then maps the QP index to a secondary component QP, which has an extended range.

摘要： Disclosed herein are innovations for bitstreams having clean random access (CRA) pictures and/or other types of random access point (RAP) pictures. New type definitions and strategic constraints on types of RAP pictures can simplify mapping of units of elementary video stream data to a container format. Such innovations can help improve the ability for video coding systems to more flexibly perform adaptive video delivery, production editing, commercial insertion, and the like.

摘要： One or more techniques and/or systems are provided for camera capture recommendation. For example, an application may operate to capture an image using a capture device (e.g., a user may use a camera of a smart phone to capture a vacation photo for sharing through a social network app). Camera parameters of the capture device and/or a preview data stream (e.g., pixel data depicting a beach “seen” by the camera in real-time) may be used to generate a camera capture recommendation (e.g., a recommendation to use a haze removal module, a high dynamic range module, a focus bracketing module, etc.). The camera capture recommendation is provided to the application. In this way, the application may selectively use, override, supplement (e.g., use an application supplied module), or modify the camera capture recommendation for application to the capture device to obtain an output image.
