Embodiment 1

[0077] A method for playing video and audio files provided by an embodiment of the present invention is introduced in detail.

[0078] refer to figure 1 , which shows a flow chart of a method for playing audio and video files in an embodiment of the present invention.

[0079] Step 100, receiving a fast-forward or fast-rewind instruction for the currently playing audio-visual file.

[0080] Wherein, the fast forward or fast rewind command includes the information of the time point of the command.

[0081] The fast-forward command includes information on the time point of the fast-forward command, and the fast-rewind command includes information on the time point of the fast-rewind command. The information of the command time point may be the time information when the fast-forward command or fast-rewind command is generated, and the time information is the time information of playing the audio-visual file. For example, the playback duration of a video file is 90 minutes. Whe...

Embodiment 2

[0091] A method for playing video and audio files provided by an embodiment of the present invention is introduced in detail.

[0092] refer to figure 2 , which shows a flow chart of a method for playing audio and video files in an embodiment of the present invention.

[0093] Step 200, receiving a fast-forward or fast-rewind instruction for the currently playing audio-visual file.

[0094] Wherein, the fast forward or fast rewind command may include the information of the time point of the command.

[0095] The fast-forward command includes information on the time point of the fast-forward command, and the fast-rewind command includes information on the time point of the fast-rewind command. The information of the command time point may be the time information when the fast-forward command or fast-rewind command is generated, and the time information is the time information of playing the audio-visual file. For example, the playback duration of a video file is 90 minutes....

Embodiment 3

[0161] A method for playing video and audio files provided by an embodiment of the present invention is introduced in detail.

[0162] refer to image 3 , which shows a flow chart of a method for playing audio and video files in an embodiment of the present invention.

[0163] Step 300, receiving a fast forward / rewind instruction.

[0164] The user requests to fast forward or rewind a sentence through the operation interface of the player, for example, by clicking a button or using a gesture to generate a fast forward or rewind instruction, and an audio-visual playback tool such as an audio-visual player receives the fast-forward or rewind instruction.

[0165] Step 302, read subtitle information.

[0166] When the player is playing, it will read the subtitle information, and record the subtitle information at the current time if there is a subtitle at the current time point where fast forward or rewind is requested.

[0167] Step 304, find the nearest sentence of subtitles...

Abstract

The invention provides an audio video file playing method and device. The method includes receiving a fast forward or a fast reverse command for an audio video file being played currently, wherein the fast forward or the fast reverse command comprises information of a command time point; searching and obtaining the initial time point of a last subtitle piece or a next subtitle piece corresponding to the command time point of the fast forward or the fast reverse command; playing the audio video file from the subtitle and the audio video frequency frame corresponding to the initial time point. By adopting the technical scheme provided by the invention, fast forward or fast reverse operation can take one subtitle piece as an adjusting interval, so that practical requirements of users are met and especially special requirements of users having special actual need, such as for learning foreign languages through video and audio, are met.

Description

technical field [0001] The invention relates to the technical field of audio and video playback, in particular to a method and device for playing audio and video files. Background technique [0002] To perform fast forward or fast rewind operations on the currently playing audio-visual files, the current technical solution is to use the progress bar to drag and drop, or use shortcut keys to fast forward or rewind according to the set time interval. [0003] However, when watching some programs, such as TV dramas, you may need to go back and repeat a sentence of a character just now, or want to skip the current sentence of a character, but dragging with the progress bar or clicking the shortcut key cannot accurately follow the Fast-forwarding or rewinding at intervals of one sentence cannot meet user needs. Contents of the invention [0004] The present invention provides a method and device for playing video and audio files to solve the problem that the existing fast-forw...
