Problems solved by technology

[0003] At the same time, the Android system does not yet have a perfect solution for webp playback. Android native controls do not support webp animations. The mainstream Fresco image playback framework has a large integration volume and cannot perform finer-grained control over playback. The rendering process is carried out through the SOC, which increases the burden on the SOC, the frame rate of the playback cannot be guaranteed, the frame rate is too low, the frame is lost, etc., and the rendering effect is not good, and the gradient color and other parts are prone to mosaics
[0004] Through the analysis of Google's generation and decoding of webp, it is found that the decoding of webp, rendering to the screen, synchronization of decoding thread and rendering thread takes a lot of time

Embodiment 1

[0028] Such as figure 2 As shown, this embodiment provides a method for solving webp freeze on Android TV, which specifically includes:

[0029] (1) Pass the path of the webp animation to the decoding module for decoding. Among them, the decoding module has encapsulated the pixel processing and memory operation parts, and the decoding module will mobilize Libframesequence for decoding, and the frame information data will be obtained after the decoding is completed. The decoding module processes the frame information data, removes redundant information, and performs data conversion to obtain pixel data that can be used for subsequent display and rendering modules.

[0030] (2) Define SurfaceView, GLSL shader renderer, and EGL rendering thread. This step mainly provides a rendering window for the rendering module. At the same time, you can set the playback mode and playback listener, and the rendering module will call back the corresponding monitoring function when the playba...

Abstract

The invention discloses a method for solving the problem of webp lag during Android TV playing, which comprises the following steps: calling a decoding module to decode a webp moving picture, carryingout secondary processing on decoded data to obtain original frame data, and transmitting the frame data to a data display module for rendering. Based on construction of a decoding module and a display module, on the basis of solving the problem that an existing webp moving picture is not played smoothly, the problems that an existing webp frame is high in invasiveness and large in size are solved, and a non-invasive solution is provided. The playing rendering effect of the webp moving picture is greatly improved, and the phenomenon that the playing of the webp moving picture is lagged and frames fall off is avoided.

Description

technical field [0001] The invention relates to the technical field of Android dynamic picture processing and rendering, in particular to a method for solving webp freeze on Android TV. Background technique [0002] At present, the development and popularity of the Android system are very high, but the hardware resources of the TV system are relatively backward compared with the mobile phone system. How to add complex animations and reduce the size of Android applications under limited hardware conditions has become an urgent problem to be solved. By analyzing and comparing the current mainstream animation and video formats, it is found that webp animation can effectively reduce the size of Android applications and restore animation effects to a high degree. [0003] At the same time, the Android system does not yet have a perfect solution for webp playback. Android native controls do not support webp animations. The mainstream Fresco image playback framework has a large in...
