Method and device for adjusting multimedia decoding information buffer area

Abstract

The invention provides a method and device for adjusting a multimedia decoding information buffer area. The method comprises the following steps: judging whether needs to redistribute the buffer area based on a multimedia parameter acquired by the decoding data when monitoring the accomplishment of the multimedia information decoding, thereby buffering the decoding data; when judging needing to redistribute the buffer area, determining redistributed buffer area based on the multimedia data; and buffering the decoding data to the redistributed buffer area. By use of the technical scheme provided by the invention, an aim of dynamically adjusting the preset buffer region based on the multimedia parameter of to-be-played multimedia information, the lagging or error condition existing in the playing of the to-be-played multimedia information is avoided when an operation of smoothly playing the to-be-played multimedia information is satisfied; and meanwhile, the occupancy of the redundant system memory can be reduced, the influence on the system running performance of the playing equipment and the running of other applications can be avoided, and the use experience of a user is improved.

Description

technical field [0001] The present invention relates to the field of information technology, in particular, the present invention relates to a method for adjusting a multimedia decoding information buffer and a device for adjusting a multimedia decoding information buffer. Background technique [0002] With the development of information technology, multimedia technology has also attracted more and more people's attention, because multimedia technology is a technology that collects, encodes, decodes and outputs audio and video signals through terminals, so as to play audio and video to users; Therefore, the application of multimedia technology to videophone, multimedia monitoring, video conferencing, multimedia teaching and other fields has brought a lot of convenience to people's life. [0003] Usually, for embedded devices with the function of playing multimedia information, the decoding process of multimedia information requires the decoding device to decode the multimedi...

However, in the prior art, the buffer area for storing the decoded data of multimedia information has been preset, and in order to ensure that the embedded device can play multimedia information of various sizes smoothly, so as to avoid jamming or even If an error occurs, the buffer area is generally preset to a large capacity, so that although the occurrence of errors when playing multimedia information can be avoided as much as possible, when the decoded data of the multimedia information is small, a large amount of memory will be unnecessarily occupied. System memory space, which affects the system performance of embedded devices
