Embodiment Construction

[0020] A method for selecting hard-decoded video playback provided by an embodiment of the present invention, such as figure 1 As shown, it is mainly included in the four core module steps of S110 (data module), S120 (demultiplexing module), S130 (decoding module), and S140 (rendering module).

[0021] A method for selecting hard-decoded video playback provided by an embodiment of the present invention, such as figure 2 As shown, it mainly includes the following steps:

[0022] Step S210, obtain the audio and video information of the streaming video to be played, capture the profile and level of the audio and video, codec number id, and create a corresponding renderer;

[0023] Step S211, combined with the specifications supported by Android for hard decoding, it is judged whether the profile and level of the audio and video are within the specifications, if not, go to M2 (that is, use soft decoding to decode and play);

[0024] Step S220, search for the mediacodec hard dec...

Abstract

The invention discloses a method of intelligently switching hard decoding to soft decoding to play a video in a mobile terminal. The method comprises the steps of demultiplexing an initial audio and video format to obtain a target audio and video; capturing video description information and video stream data of the target audio and video; filtering proper profile and level attributes according tovideo stream information, and performing soft decoding on improper profile and level attributes by using FFmpeg; searching a proper hard decoder name according to the video stream information, if proper hard decoder name is not found, performing soft decoding by using FFmpeg; creating a hard decoder according to hard decoding name, if creation fails, performing soft decoding by using FFmpeg; decoding audio data by using default FFmpeg; decoding the data stream data by using the hard decoder, and if decoding fails, performing soft decoding by using FFmpeg again; and rendering decoding data to play the target video, if play fails, performing soft decoding by using FFmpeg again. In the prior art, hard decoding cannot be used preferentially to support multiple multimedia video formats and multiple stream media protocols in Android. The method solves the above problem, lowers CPU use ratio in play and slows down power consumption by CPU in play.

Description

technical field [0001] The invention relates to the fields of multimedia data processing and audio and video decoding, in particular to a method for intelligently switching hard decoding and soft decoding to play video in a mobile terminal. Background technique [0002] Hard decoding is decoding realized by hardware, and soft decoding is to allow CPU to perform video decoding processing through software. [0003] The mobile device operating system Android (Android) has been more and more respected in the mobile field since it was released in 2007, and now it has occupied more than half of the country's share. Strong demand, a kind of multimedia system player that is used in Android is provided in the prior art, this player supports audio-video hard decoding, but the audio-video format that itself supports is too few, and the streaming media agreement that supports is also limited, can't Satisfies a wide variety of multimedia formats and streaming media protocols. In additio...
