Abstract

The invention discloses a video decoding method and device and a terminal device. Through the creation and starting of multiple decoding threads, the decoding threads are independent mutually and are in concurrent operation, thus multiple picture groups can be decoded at the same time, compared with an existing method of decoding through a serial mode, the decoding speed is raised by multiple times, thus the online playing of an HD video file with a large amount of data can be realized, and a jam phenomenon is avoided.

Description

technical field [0001] The present application relates to the technical field of video processing, and in particular to a video decoding method, device and terminal equipment. Background technique [0002] With the development of Internet technology, using terminals that can access the Internet, users can not only browse text and picture information, but also watch video files on the Internet; compared to downloading video files to the terminal and then watching them, users prefer to directly view them through It is not only convenient and quick to watch video files in the Internet online with a browser or a dedicated player, but also saves storage space on the terminal. Since the video file needs to be decoded before playing to obtain the image corresponding to each video frame, in order to play the video file online, the terminal needs to perform two operations of decoding and playing at the same time, and the decoded images of each frame are directly added to the playback...
