摘要： Video decoding innovations for multithreading implementations and graphics processor unit (“GPU”) implementations are described. For example, for multithreaded decoding, a decoder uses innovations in the areas of layered data structures, picture extent discovery, a picture command queue, and/or task scheduling for multithreading. Or, for a GPU implementation, a decoder uses innovations in the areas of inverse transforms, inverse quantization, fractional interpolation, intra prediction using waves, loop filtering using waves, memory usage and/or performance-adaptive loop filtering. Innovations are also described in the areas of error handling and recovery, determination of neighbor availability for operations such as context modeling and intra prediction, CABAC decoding, computation of collocated information for direct mode macroblocks in B slices, reduction of memory consumption, implementation of trick play modes, and picture dropping for quality adjustment.

摘要： Video image stabilization provides better performance on a generic platform for computing devices by evaluating available multimedia digital signal processing components, and selecting the available components to utilize according to a hierarchy structure for video stabilization performance for processing parts of the video stabilization. The video stabilization has improved motion vector estimation that employs refinement motion vector searching according to a pyramid block structure relationship starting from a downsampled resolution version of the video frames. The video stabilization also improves global motion transform estimation by performing a random sample consensus approach for processing the local motion vectors, and selection criteria for motion vector reliability. The video stabilization achieves the removal of hand shakiness smoothly by real-time one-pass or off-line two-pass temporal smoothing with error detection and correction.

摘要： Disclosed herein are representative embodiments of methods, apparatus, and systems for manipulating bitstreams of digital media data compressed according to a compression standard. Also disclosed are representative embodiments of methods, apparatus, and systems for evaluating compliance of an encoded bitstream of digital media data with a compression standard. In one exemplary embodiment, a conforming bitstream of compressed digital media data is input. One or more of the parameters in the bitstream are selectively altered into parameters that do not conform to the video compression standard. The selective alteration can be performed such that parameters that would make the bitstream non-decodable if altered are bypassed and left unaltered. A non-conforming bitstream that includes the one or more selectively altered parameters is output.

摘要： Techniques and tools for reducing latency in video decoding for real-time communication applications that emphasize low delay. For example, a tool such as a video decoder selects a low-latency decoding mode. Based on the selected decoding mode, the tool adjusts output timing determination, picture boundary detection, number of pictures in flight and/or jitter buffer utilization. For low-latency decoding, the tool can use a frame count syntax element to set initial output delay for a decoded picture buffer, and the tool can use auxiliary delimiter syntax elements to detect picture boundaries. To further reduce delay in low-latency decoding, the tool can reduce number of pictures in flight for multi-threaded decoding and reduce or remove jitter buffers. The tool receives encoded data, performs decoding according to the selected decoding mode to reconstruct pictures, and outputs the pictures for display.
