Video decoding method adapted to Android system and device thereof

Abstract

The invention provides a video decoding method adapted to an Android system and device thereof. The video decoding method comprises the following steps: the step of transmitting video information to a decoding module; the step of acquiring cache information from the decoding module; the step of creating a cache module according to the cache information through a display module; the step of decoding code stream data in the cache module through the decoding module; the step of saving the decoded video information at the cache module; and the step of displaying the video data through the display module. The invention further provides a video decoding device using the video decoding method. The display module applies to the cache module so that the setting of co-caching the decoding and displaying is in favor of reducing the application of the number of cache modules while reducing the copying times; the method comprises applying to the cache module through the acquisition of the cache information corresponding to the video information so as to effectively reduce the application size and number of the cache module, and then to improve the video decoding performance and the decoding efficiency.

Description

technical field [0001] The present invention relates to the field of video decoding, in particular to a video decoding method adapted to an Android system and a video decoding device using the method. Background technique [0002] Android (Android) system is a Linux-based free and open-source operating system developed by Google. It is mainly used for mobile devices such as smart phones and tablet computers. market share. The success of the Android system is due to its practice of developing source code to a certain extent, which opens up many permissions and interfaces of the system, so that each hardware manufacturer can adapt to the android system according to its own hardware characteristics. In terms of multimedia, android defines two sets of interfaces, mediaplayer and mediacodec. The system's own nuplayer and stagefrightplayer inherit from mediaplayer, and softomx is connected to mediacodec. Hardware manufacturers can combine their own codec resources (including hard...

Problems solved by technology

For now, buffer management has disadvantages such as too much buffer space to apply for, and low copy efficiency of buffers.

If the requested buffer space is too large, it will occupy more system memory and affect the fluency of the system. If the buffer copy efficiency is low, the overall encoding and decoding performance will be reduced, and the power consumption of the device will increase.
