Abstract

The invention provides a multimedia video playing system applied to an Android platform and a multimedia video playing method applied to the multimedia video playing system of the Android platform. According to the invention, two buffer groups (input and output) are provided for a file parser, an OMXCodec, a video decoder, a display image layer module, a Stagefright and an image synthesis module to use through a memory allocator, thereby being capable of avoiding problems in the prior art that the number of buffer groups is large, a requirement for the memory size is high in playing, a large amount of data copy exists among different buffer groups, CPU resources are occupied, and the overall playing performance is affected.

Description

technical field [0001] The invention relates to the technical field of multimedia video playback, in particular to a multimedia video playback system and method applied to an Android platform. Background technique [0002] In the field of smart phone terminals, the multimedia video playback function has become an indispensable requirement, and at the same time, users' requirements for the image quality of mobile phone terminals are also gradually increasing. At present, high-definition video with 1080P resolution (1920×1080) is very common, which puts forward higher requirements for the multimedia video playback capability of mobile terminals. [0003] Specifically, please refer to figure 1 , which is a schematic diagram of a frame structure of an existing multimedia video playback system applied to an Android platform. Such as figure 1 As shown, the existing multimedia video playback system applied to the Android platform includes: file parser 10, OMXCodec11, video decod...
