Embodiment Construction

[0045] The main idea of ​​the present invention is to solve the limitation problem of the audio and video file format and audio and video encoding format of the audio and video player of the mobile terminal, and also to solve the limited hardware resources of the mobile terminal and the multiple audio and video formats supported by the mobile terminal. Contradiction between the two caused by resource consumption. Specifically, the system and method of the present invention can determine an optimal runtime dynamic adjustment scheme according to the hardware resource parameters of the mobile terminal and the configuration information of the user. The adjustment scheme can be based on different audio and video formats and playback modes. (Play mode refers to the way the user uses the player, which can be local play mode or network play mode) Dynamically adjust the resource occupancy to ensure that the mobile terminal can meet the current needs of the user, so that the mobile terminal...

Abstract

The invention discloses a system for supporting self-adaption of decoding audio and video and a method thereof. The system comprises a strategy configurator, playing frame equipment, a memory device and a module manager, wherein the strategy configurator is used for determining the processing strategy adopted by the module manager according to the configured information by a user; the playing frame equipment is used for storing a dynamic binding protocol of supporting playing of various formats of audio-video files; the memory device is used for storing modules for processing audio-video files with different formats; and the module manager is used for carrying out loading and unloading management on the modules in the memory device according to the processing strategy and calling the dynamic binding protocol corresponding to the format into the memory device from the playing frame equipment according to the format of the audio-video files to be processed and carrying out decoding on the audio-video files after carrying out binding with the modules with corresponding formats in the memory device. The invention solves the problem that the audio-video player of the mobile terminal restricts the audio-video file formats and audio-video coding formats.

Description

Technical field [0001] The present invention relates to the field of multimedia audio and video in an embedded system. Specifically, the present invention relates to a system and a method for supporting self-adaptive audio and video decoding. Background technique [0002] At present, with the continuous improvement of the software and hardware level of embedded systems, various multimedia audio and video playback applications based on embedded systems have been greatly developed. Take the mobile terminal (mobile phone) system as an example. Different manufacturers have successively launched their own audio and video playback software, bringing new audiovisual enjoyment to the majority of mobile phone users. [0003] However, faced with a wide variety of audio and video encoding formats and file formats, as well as relatively limited mobile phone hardware resources. The audio and video players of different mobile terminals have strict regulations on audio and video files. Only cer...
