Abstract

The invention discloses an Android video decoding hardware acceleration method based on a Linux desktop video card, which is applied to an environment in which a Linux system is compatible with an Android container and comprises the following steps: S1, loading a video decoding service of the Android container and initializing a video decoder; s2, the video decoder initializes a video decoding hardware acceleration interface; s3, the video decoder sends the video data packet to a video decoding hardware acceleration interface; s4, the video decoding hardware acceleration interface transmits the data packet into the Linux kernel, and the video card device decodes the data packet into a video frame; s5, the video decoder retrieves the decoded video frame through the video decoding hardware acceleration interface; and S6, the video decoding service sends the video frame to a video program for display. According to the method, the performance loss caused by video decoding by using a CPU (Central Processing Unit) is reduced, and the efficiency of Android video decoding is improved.

Description

technical field [0001] The invention relates to the technical field of Android video decoding, in particular to an Android video decoding hardware acceleration method based on a Linux desktop graphics card. Background technique [0002] In recent years, with the growth of Android (Android) users and the maturity and development of Android hardware and software products, the Android application ecology has shown explosive development. In many fields, it has surpassed the Windows application ecology and iOS application ecology, and has become the most widely used application ecology. Developed based on the Linux kernel, Android is currently the Linux operating system with the highest market share in the mobile terminal market, and has an excellent ecological environment in the field of mobile terminals; the Windows system occupies the largest share of the PC market. system, there are huge security risks in information network security; and the Linux operating system, as the p...
