Embodiment Construction

[0042] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0043] The invention provides an audio and video playing method.

[0044] refer to figure 1 , figure 1 It is a schematic flowchart of the first embodiment of the audio and video playing method of the present invention.

[0045] In this embodiment, the audio and video playback method includes:

[0046] Step S10, in the process of playing audio and video files while decoding, if it is detected that the audio and video currently being played is abnormal, then obtain the corresponding time point of the currently decoded video;

[0047] In this embodiment, the audio and video files are played while being decoded. Specifically, the terminal first decodes a part of the audio and video, then plays the decoded audio and video, and continues to decode the rest of the audio and video files when playing the decoded audio and v...

Abstract

The invention discloses an audio-video playing method. The audio-video playing method comprises the following steps: during synchronous decoding and playing of an audio-video file, if an abnormality of the currently played audio-video file is detected, obtaining a corresponding time point of a current decoded video; when the obtained time point is a preset skipping time point, skipping to an audio-video file position of the obtained time point, and carrying out decoding of an audio file and a video file; and playing the decoded audio-video file from the obtained time point. The invention further discloses an audio-video playing system. The method and system provided by the invention has the advantage that audio-video synchronization during audio-video playing is maintained.

Description

technical field [0001] The invention relates to the field of audio and video playback, in particular to an audio and video playback method and system. Background technique [0002] At present, audio and video playback is already an essential function of TV and other equipment. When users play audio and video, sometimes they find that the image and sound are abnormal, that is, the image and sound are out of sync. For example, the character has started to speak, but the sound has not yet come out. , or the voice comes out, but the character has not started to speak, so the user looks particularly awkward. [0003] The reason for abnormal audio and video is mainly due to the various audio and video production tools, and the edited audio and video files are also different, and even do not meet the standards. As a result, the TV is prone to errors during audio and video decoding, such as skipping some data frames during decoding of images or sounds, so that the time axis of the ...
