Problems solved by technology

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

Abstract

The present invention provides a method and device for adjusting a buffer of multimedia decoding information. The method includes: when it is detected that the decoding of multimedia information is completed, based on the multimedia parameters obtained according to the decoded data, it is judged whether it is necessary to re-allocate the buffer to buffer all The decoded data; when it is judged that the buffer needs to be reallocated, the reallocated buffer is determined based on the multimedia parameters; and the decoded data is cached in the reallocated buffer. By applying the technical solution of the present invention, the purpose of dynamically adjusting the preset buffer area based on the multimedia parameters of the multimedia information to be played can be realized, and the multimedia information to be played can be played smoothly, and the occurrence of stuck or stuck when playing the multimedia information to be played can be avoided. At the same time, it can reduce the occupation of redundant system memory, so as to avoid affecting the system operating performance of the playback device and the operation of other applications, and improve the user experience.

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...
