Embodiment 1

[0030] refer to figure 1 , showing a flow chart of a video decoding method in an embodiment of the present invention, specifically including:

[0031] Step 101, monitor whether the video source of the video is switched from the first video source to the second video source during the video playing process, wherein the resolution of the second video source is lower than the resolution of the first video source.

[0032] Specifically, in the embodiment of the present invention, during the video playing process, the mobile terminal can monitor in real time whether the video source of the currently playing online video is switched. In one embodiment, if the network is blocked, a corresponding module in the mobile terminal will switch the current resolution version of the video (ie, the first video source) to a low-resolution version (ie, the second video source). In another embodiment, if the user fast-forwards or rewinds the video, due to network and hardware constraints, the vi...

Embodiment 2

[0039] refer to figure 2 , showing a flow chart of a video decoding method in an embodiment of the present invention, specifically including:

[0040] Step 201, creating a video cooperative decoder.

[0041] Specifically, in the embodiment of the present invention, the mobile terminal can invoke multiple tools (that is, program codes for realizing different functions) in the mobile terminal to generate a video collaborative decoder. And, the mobile terminal can generate a dynamic link library corresponding to the video cooperative decoder, so that when the mobile terminal invokes a function in the video cooperative decoder, the corresponding tool can be directly invoked through the dynamic link library.

[0042] Step 202, monitor whether the video source of the video is switched from the first video source to the second video source during the video playing process.

[0043]Specifically, in the embodiment of the present invention, during the video playing process, the mobil...

Embodiment 3

[0064] refer to image 3 , shows a block diagram of a mobile terminal 300 in an embodiment of the present invention. Specifically include:

[0065] The monitoring module 301 is configured to monitor whether the video source of the video is switched from the first video source to the second video source during video playing, wherein the resolution of the second video source is lower than that of the first video source.

[0066] Specifically, in the embodiment of the present invention, during the video playing process of the mobile terminal, the monitoring module 301 can monitor in real time whether the video source of the currently playing online video is switched. In one embodiment, if the network is blocked, a corresponding module in the mobile terminal will switch the current resolution version of the video (ie, the first video source) to a low-resolution version (ie, the second video source). In another embodiment, if the user fast-forwards or rewinds the video, due to ne...

Abstract

The embodiment of the invention provides a video decoding method and a mobile terminal. The video decoding method comprises the following steps: monitoring whether a video source of videos is switchedfrom a first video source to a second video source in a video playing process, wherein the resolution of the second video source is lower than the resolution of the first video source; if yes, calling a video software decoder to decode the videos; and when monitoring that the video source of the videos is switched from the second video source back to the first video source, calling a video hardware decoder to replace the video software decoder to decode the videos. According to the scheme of the invention, online playing videos can be decoded through the cooperative effect of calling the software decoder and the hardware decoder, and thus the phenomena of video lagging and audio-video non-synchronization caused by networks and other reasons in the process that the video source of online videos is switched can be effectively prevented, and the user experience can be further enhanced.

Description

technical field [0001] Embodiments of the present invention relate to the field of video technology, and in particular, to a video decoding method and a mobile terminal. Background technique [0002] In the era of mobile Internet, with the promotion and popularization of smart terminals, users are constantly pursuing high-quality audio-visual experience. Among them, high compression ratio, high bit rate, high resolution, multi-channel, and lossless audio sources have gradually become standard configurations, and users have higher and higher requirements for multimedia quality. Network video on demand (Video-on-demand, VOD) and live broadcast have become important functions of the mobile terminal video function, and the mobile terminal can play corresponding video programs according to the needs of users. [0003] The video-on-demand process in the prior art is mainly as follows: when a user sends a request for a video, the streaming media service system retrieves the corres...
