Method and system for online playing F4v videos on mobile device

Abstract

The embodiment of the invention provides a method and system for online playing F4v videos on a mobile device. A video resource server is requested for an F4v video file and matched MP4 header data, and the received MP4 header data, an F4v metadata file in the received F4v video file, and an audio and video stream file in segmented videos in the received F4v video file are sequentially transmitted to a video player one after another. Due to the fact that the data transmitted to the video player meet the packaging format of MP4 videos, video format conversion is not needed, and the video player can call a video card to decode and play the videos in a decoding mode for the MP4 videos. According to the method and system, decoding efficiency can be effectively improved, the operating burden on a CPU is relieved, and consumption of the operational capacity of the CPU is avoided.

Description

technical field [0001] The present invention relates to the technical field of video playback on mobile devices, in particular to a method and system for playing F4v videos online on mobile devices. Background technique [0002] The F4V video format uses H264 high-definition encoding. Compared with the traditional FLV video format, it can achieve higher resolution with the same volume and support higher bit rates. With the continuous improvement of network bandwidth, people have higher and higher requirements for video clarity, so the F4V video format will gradually become the mainstream format of network streaming media. [0003] Because mobile devices are easy to carry, users often watch online videos through mobile devices. Most of the existing mobile devices are equipped with a graphics card GPU. For MP4 format video, the video player in the mobile device can directly call the graphics card to decode multiple formats of video to play MP4 format video, that is, play MP4 ...

AI Technical Summary

Problems solved by technology

However, the video player of the mobile device does not support the playback of the F4v format, and cannot directly call the graphics card to decode the F4v format video. It can only be converted to a format supported by the video player through the CPU, and then the graphics card is called to decode it. That is, play F4v format video through soft decoding

[0004] However, compared with hard decoding, soft decoding has lower decoding efficiency, and the conversion of video formats will increase the operating burden of the CPU, which greatly consumes the computing power of the CPU.
