Problems solved by technology

[0003] In the prior art, skipping playback or manually dragging the progress bar is a manual operation, which will affect the smooth viewing experience, and it is difficult for the user to browse all the content, and may miss the video content that is really interesting; when the user uses double-speed playback, although he can Watching the complete plot, but content that the user is not interested in will still be played, requiring frequent user intervention to adjust the speed, and the key plot still needs the user to manually resume normal playback to ensure the viewing effect. If the double speed is too fast, it is easy to miss important information, and the double speed is too slow to waste time. , the user experience is low, and the power consumption of the playback device is high

Abstract

Embodiments of the invention provide a method and system for playing audios and videos at a multiplied speed based on content awareness, a storage medium and equipment. According to a technical scheme provided by the embodiments of the invention, the method comprises the following steps: reading a target audio / video; inputting the target audio / video into an AI model with a specified function, and outputting an identification result; according to the identification result, determining a speed multiplication instruction from a plurality of set speed multiplication instructions to be selected; and playing the target audio / video based on the speed multiplication instruction. According to the invention, the playing speed is dynamically adjusted based on the psychological perception of a user in auditory sense and visual sense, thereby improving user experience, and deeply mining the low power consumption potential of playing associated equipment such as hardware acceleration equipment.

Description

【Technical field】 [0001] The present invention relates to the technical field of double-speed video playback, in particular to a content-aware-based double-speed playback method, system and storage medium. 【Background technique】 [0002] At present, all kinds of video programs are emerging in an endless stream, and a large number of variety shows and long-form TV series are available for users to watch. When users watch video programs, if they want to finish watching a video program as soon as possible, users can choose double-speed playback, skip playback or manually drag the progress Article; In double-speed playback, the digital signal processor (Digital Signal Processing, referred to as: DSP) is configured to perform calculations based on the preset decoding speed of the application layer. The application layer settings are often based on user settings or operating system settings. The power consumption policy is defined. [0003] In the prior art, skipping playback or ...
