Code stream data decoding method, computer device and computer readable storage medium

Abstract

The invention discloses a code stream data decoding method, a computer device and a computer readable storage medium. The method comprises the steps that a code stream data manger establishes a code stream detection thread; the code stream data manager receives code stream data, the code stream detection thread detects the code stream data, and the start-stop positions of the code stream data of aframe of image in the code stream data are detected; a decoder obtains the code stream data of the frame of image, and decodes the received code stream data of the frame of image. The invention further provides the computer device achieving the method and the computer readable storage medium. Two threads are used simultaneously to execute code stream data detection and a code stream data decodingoperation respectively, the phenomenon that the two threads are executed on the decoder simultaneously is avoided, the decoding efficiency of the decoder is improved, and video playing is smoother.

Description

technical field [0001] The present invention relates to the field of decoding code stream data, in particular to a method for decoding video code stream data, a computer device for realizing the method, and a computer-readable storage medium. Background technique [0002] With the development of electronic technology and network technology, the transmission of video data through the network has been widely used in Internet TV, distance education, digital cinema, radio and television and other industries. Due to the large amount of video data, in order to efficiently transmit the video data, it is often necessary to encode the video data at the sending end of the video signal, and perform data decryption at the receiving end of the video data. Therefore, video codec technology, as a technology for processing image information data, plays an important role in the dissemination of video data, especially in the popularization of Internet TV. [0003] Moreover, thanks to the imp...

Problems solved by technology

[0010] However, since the existing solution is to perform code stream detection and drive decoder and other enabling hardware to perform decoding operations in the same thread, the operation of detecting code streams has the problem of long time consumption. When the playback scene is small When the size of the video is small, the time consumed to detect the code stream is relatively short, which has little impact on the overall performance of the decoder.

If you are playing a video with a large size and a complex scene (such as a 4K 60fps video with a playback rate of 100Mbps), the time consumed to detect the code stream will reach the millisecond level, and the time-consuming fluctuation is large (in the CPU When the load is heavy, the time-consuming peak of detecting the code stream reaches more than ten milliseconds), which reduces the overall performance of the decoder and directly affects the playback performance of the video, such as video playback freezes
