Embodiment Construction

[0037] The realization of the present invention is based on such considerations, and existing video files can be stored in the storage module of the VOD terminal in the following manner:

[0038] P1

P2

P3

file header

video data

keyframe index

[0039] The video file includes three parts, the first part P1 is the file header, the second part P2 is the video data, and the third part P3 is the key frame index.

[0040] The video file key frame index can be the corresponding index information table of the playback time t and the value n representing the byte offset, as shown in the following table,

[0041] time (t)

1s

Abstract

The invention provides a method and a device for displaying a dragging progress bar. The method comprises the steps of: finding out corresponding latest timestamp from a key frame index at a time point of the progress bar when a user drags, obtaining byte offset according to the timestamp, and then obtaining key frame data from a video file via the byte offset and displaying the key frame. Therefore, the current frame does not need to be calculated when the user continuously drags; the current frame is replaced by the key frame to carry out real-time display rapidly; the problem of delayed display caused by searching the key frame and calculating the current frame too frequently is avoided; real-time display is achieved; and the experience of user fluency is also improved.

Description

technical field [0001] The invention relates to the field of video playback, in particular to a method and device for displaying a video playback dragging progress bar. Background technique [0002] With the development of computer technology and network technology, it has become a leisure way for people to play various video files online or locally using terminals such as personal computers and mobile phones. [0003] Existing video display devices mainly include a player module and a user interaction interface module running on a terminal, such as figure 1 shown. When the video display device is playing the local video, the playback controller unit in the player module controls and schedules the data communication interface unit and the file reading unit to read the video files stored in the storage module in the terminal, and separate the audio and video through the audio and video separation unit. The video data is decoded by the audio and video decoding units and then...
