Embodiment Construction

[0046] Video dragging is a method of requesting video content by range, which is divided into two methods: time range and file offset range. For video dragging according to the time range, the server needs to obtain the corresponding offset in the file through calculation, and return the data to the user according to the offset range.

[0047] In the prior art, the dragging of FLV video files is generally realized according to the list of keyframes (keyframes) in the script tag (script tag), and the list of keyframes combines the time of the keyframe and the offset in the file one by one. Correspondingly, but FLV files do not necessarily have a list of keyframes.

[0048] For FLV files without a list of keyframes, the existing method of providing video files is to traverse from the first data frame of the file to the last data frame at the end of the file to find key frames, and combine the found key frames with The start time of the user's play request is compared one by one...

Abstract

The invention discloses a method and a device for providing a video file. The method comprises the following steps of obtaining a search initial position of the video file according to a received playing request from a client; and determining corresponding data frames according to the search initial position and returning the content of the video file corresponding to the determined data frames to the client to play, wherein the video file comprises more than two data frames. According to the method, the providing speed of the video file can be improved, and the pressure on a disk is reduced.

Description

technical field [0001] The invention belongs to the technical field of network video, in particular to a video file providing method and device. Background technique [0002] FLV (Flash Video) streaming media format is a new video format. FLV video files can not only be imported into the flash memory (Flash) easily and quickly, but also can protect the copyright of video files, and can also play videos without using local Microsoft or REAL players. At present, almost all large-scale video websites use FLV video files, which is the fastest growing and most widely used video transmission format. [0003] Video dragging is a method of requesting video content by range, which is divided into two methods: time range and file offset range. In the prior art, the dragging of FLV video files is generally realized according to the list of key frames (keyframes) in the script tag (script tag), and this list corresponds the time of the key frames to the offset in the flash video file ...
