AI Technical Summary

Technical Problem

In the video playback, the existing technology is prone to lag problems when the playback speed is too high. This is mainly due to the performance limitations of the demultiplexing and decoding modules, the multi-core processor and concurrent processing cannot be effectively utilized, resulting in the inability to meet the high-speed playback requirements.

Method used

By cutting the audio and video files to be played into multiple shards, and generating shard description information for each shard, distributing them to multiple processing modules for concurrent demultiplexing, multiplexing and decoding processing, according to the target speed The playback value and current playback time render the audio and video data, and use multiple concurrency methods to adapt to the high-speed playback requirements.

Benefits of technology

It effectively avoids lag during video playback, improves the smoothness and stability of high-speed playback, makes full use of the performance of multi-core processors, and realizes high-speed video playback.

Abstract

The invention provides a video playing method and device, video playing equipment and a storage medium, the method is applied to the video playing equipment, at least two pieces of fragment description information corresponding to a to-be-played audio and video file are generated according to the to-be-played audio and video file, the fragment description information is used for recording index information of corresponding fragments, and the index information of the corresponding fragments is stored in the storage medium. And distributing the at least two pieces of fragment description information to different audio and video demultiplexing, multiplexing and video decoding processing modules in the video playing equipment, so that each processing module processes an audio and video file corresponding to the corresponding fragment to obtain audio and video data output by each processing module. And rendering all audio and video data according to the target speed multiplication playing value and the current audio and video playing time. According to the technical scheme, a multi-concurrence mode is adopted, the to-be-played audio and video file is cut and then is subjected to demultiplexing, multiplexing and the like, so that the requirement of target multi-speed playing is met, and the fluency of video playing is ensured.
