Problems solved by technology

[0004] For the above problems, the common technical solution is to directly use different player instances for different hardware decoding methods. However, when the player instance used cannot play the video, it needs to use other player instances to play again. The method is simple and rude, with insufficient flexibility and poor user experience

Embodiment Construction

[0044] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the embodiments of the present invention, and are not intended to limit the embodiments of the present invention.

[0045] Due to the diversity of the Android system, the hardware decoding scheme in the player based on the Android system needs to be corresponding to the Android system, so that the player can work. In order to adapt to different Android systems, existing players need to be improved. like figure 1 Shown is the main flow of a method for decoding video in an embodiment of the present invention, the method is applicable to a player, and the method includes the following steps:

[0046] Step S11: When the decoding preparation of the video data stream to be decoded is completed, according to the information of the terminal playing ...

Abstract

The invention discloses a method, device and player for decoding video. The method comprises the following steps: after preparing the decoding of data streams of the video to be decoded, according to the information of a terminal playing the data streams of the video, selecting a decoding scheme corresponding to the information from a preset decoding scheme; transferring the selected decoding scheme to decode the data streams of the video to be decoded. Through the adoption of the method disclosed by the invention, different decoding schemes can be encapsulated in the player, and the structures of different decoding types can be taken account of; when the decoding scheme needs to be replaced, buffer again and decoding preparation are not needed, and the decoding schemes can be directly switched, so that the dynamic switching is realized, users hardly sense the dynamic switching, and the use experience of the user is improved.

Description

technical field [0001] The present invention relates to the technical field of players, and more specifically, to a method, device and player for decoding video. Background technique [0002] At present, video decoding methods mainly include software decoding and hardware decoding. Software decoding refers to decoding directly by CPU (Central Processing Unit, central processing unit). Since the resolution of high-definition video is much higher than that of general-format video, the bit rate of high-definition video is very high, coupled with the compression rate of mainstream encoding algorithms High, the amount of decoding operation is very large, so software decoding will greatly consume the computing power of the CPU; hardware decoding is to decode high-definition video through the video acceleration function of the graphics card, so hardware decoding can relieve the CPU from the heavy video decoding operation Released in the middle, so that the terminal has the ability...
