Problems solved by technology

[0004] Due to the high computational complexity of video decoding, using the video decoding module that comes with a third-party application will consume a large amount of CPU (Central Processing Unit, central processing unit) computing resources, resulting in a large power consumption of the terminal when playing multimedia data
In addition, when playing higher-resolution video data on a terminal with low configuration, t

Abstract

The invention discloses a playing method of multimedia data and a device, and belongs to the field of the internet. The method comprises calling a local-end hardware video decoder interface based on a multimedia file to initialize a local-end hardware video decoder, performing container format analyses on multimedia data aiming at each frame of the multimedia data in the multimedia file to obtain a frame of video code stream, performing decoding on the video code stream through the hardware video decoder to obtain decoded video data if the hardware video decoder is successfully initialized, performing the decoding on the video code stream through an audio decoding module contained in a multimedia player to obtain decoded audio data, and performing playing of the multimedia data based on the decoded vide data and the decoded audio data. A computing resource of a CPU can be saved, local-end power consumption when the multimedia data is played is reduced then, and playing quality of the multimedia data is improved.

Description

technical field [0001] The invention relates to the Internet field, in particular to a method and device for playing multimedia data. Background technique [0002] With the development and popularization of electronic smart terminals, the terminal can not only support the built-in application programs in the system, but also support third-party application programs. Third-party applications may include browsers, instant messengers, multimedia players, and the like. When playing multimedia data, the terminal can not only use the built-in multimedia player in the system to play, but also use the multimedia player in the third-party application program to play. [0003] At present, the process that the terminal uses the multimedia player in the third-party application program to play multimedia data is as follows: the terminal receives multimedia data, and performs container format analysis on the multimedia data to obtain compressed and encoded video code stream and audio cod...
