Problems solved by technology

[0005] Aiming at the problems in the prior art that the frequency of audio and video switching is relatively high, large resource consumption will still be occupied during the switching process, the audio and video switching is not smooth, and the user experience is poor, the present invention provides a method that separates the download module from the playback module Come out and transform it into a cache module to support the download of multi-channel videos, so that after switching videos, you can complete the audio and video switching without creating a new player instance, a method for fast switching of network audio and video

Embodiment 1

[0044] A method for fast switching of network audio and video, according to the attached Figure 4 And attached Figure 5 It can be seen that its playback module includes a data reading module, a decoding module, an audio and video synchronization module, and a rendering module; before the caching module performs audio and video caching, it needs to request the server to download audio and video. Slow, unable to perform fast switching; poor user experience.

Embodiment 2

[0046] On the basis of embodiment 1, the difference from embodiment 1 is that it includes a playback module and a cache module with a download function in this embodiment, and the method includes,

[0047] Audio and video caching, setting audio and video information to the cache module, the cache module caches the acquired audio and video information, and generates a corresponding handle;

[0048] For audio and video playback, the playback module obtains the corresponding handle from the cache module, and obtains the corresponding audio and video data through the handle, and then plays the audio and video data;

[0049] For audio and video switching, the playback module obtains the handle corresponding to the new audio and video, and obtains the corresponding audio and video data through the handle, and then plays the audio and video data to complete the audio and video switching.

[0050] By separating the download module from the player and placing it in the cache module, it...

Embodiment 3

[0076] On the basis of the above embodiments, this embodiment also includes a request for data after switching the video, and the caching module continues to request the pre-cached data from the server. The caching module will continue to request the data after the pre-cached data from the server to ensure the continuity of video playback.

Abstract

The invention relates to the related technical field of audio and video playing, and discloses a network audio and video fast switching method, which comprises the following steps that: audio and video information is set to a cache module, and the cache module caches the acquired audio and video information and generates a corresponding handle; the playing module obtains the corresponding handle from the cache module, obtains the corresponding audio and video data through the handle, and plays the audio and video data; and the playing module obtains the handle corresponding to the new audio and video, and plays the audio and video data to complete audio and video switching. According to the method and the device, the downloading module is independent from the playing module, a player instance does not need to be frequently created and released, only the decoding module and the rendering module need to be reset under specific conditions, other modules do not need to be reset, time loss and system resource overhead in the switching process are greatly saved, and the switching efficiency is improved. The switched video content can be seen more quickly, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field related to audio and video playback, and in particular to a method for quickly switching network audio and video in short videos. Background technique [0002] Under the traditional player implementation, when the user is watching a video, if he wants to switch to the next player, he usually needs to close and release the resource download module, decoding module, rendering module, etc. occupied by the previous player, and then allocate A new player instance to receive new video stream data. [0003] After the user switches the video, the player needs to stop the previous playback, release the download module, decoding module, audio and video synchronization module, and rendering module, and then re-create the player instance, request a new video source address, and re- Create all instances of download module, decoding module, audio and video synchronization module, rendering module, etc. [0004] For exam...
