Method and device for processing video data

Abstract

The invention provides a method and apparatus for processing video data. The method comprises the following steps: N positions of N-bit binary numbers are equally divided into M data layers in advance, wherein the positions in each data layer are adjacent, P positions in each layer form P-bit binary numbers, N=M*P, and N, M and P are all positive integers; each pixel of video data to be processed is converted into a binary number, and the pixel binary number corresponding to each pixel is obtained; the pixel binary number corresponding to each pixel is converted into an N-bit pixel binary number; a value of each N-bit pixel binary number at each position is divided into a corresponding position in a corresponding data layer, and a P-bit pixel binary number of each pixel in each data layer is obtained; and a thread is distributed to each data layer, and parallel processing is performed on all the P-bit pixel binary numbers in each data layer through each thread. The method and apparatus for processing the video data, provided by the invention, can improve the efficiency of processing the video data.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method and device for processing video data. Background technique [0002] With the rapid development of high-speed network and computer software and hardware equipment, the traditional low-resolution, low video stream video capture technology has been eliminated by high-definition or ultra-high-definition video capture technology. However, with the continuous improvement of video quality, the volume of video files is also increasing, and the hardware requirements for video encoding and decoding are also increasing, but the traditional encoding and decoding technology has not yet achieved a fundamental breakthrough. [0003] In the prior art, a large amount of video codec work can only be supported by upgrading the hardware level. Even so, the time required for video rendering, editing, and encoding work is still increasing. The reason is that, in addition to the fact...

Problems solved by technology

However, with the continuous improvement of video quality, the volume of video files is also increasing, and the hardware requirements for video codec are also constantly improving, but the traditional codec technology has not yet achieved a fundamental breakthrough.

[0003] In the existing technology, a large number of video codecs can only be supported by improving the hardware level. Even so, the time spent on video rendering, editing, and encoding is still increasing.

The reason is that, in addition to the fact that the increase in data flow has indeed increased the requirements for hardware processing, the main reason is that traditional codec technology has never been able to break through the multi-thread processing bottleneck in units of video frames.

When encoding and decoding video in the prior art, it can be processed simultaneously by multiple threads, but the cooperation between different threads can only wait for the synchronization of other threads by blocking, which makes the utilization of computer resources difficult. Saturation, making it less efficient to process video data
