Problems solved by technology

Therefore, the natural limitation that a single SWF file in Flash cannot operate at 16,000 frames will have to become an obstacle that must be overcome to convert video files with a very long length.

Embodiment Construction

[0046] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0047]The key of the solution of the present invention lies in a unique feature of the SWF file: the SWF file allows other SWF files to be embedded in a certain designated position, and this feature is generally used to add user-defined advertisements and small trademark elements. This program will make perfect use of this feature to make the FLV video into a sub-SWF file that can be mistaken for the main SWF file as an advertisement. After embedding the main SWF file without interfering with each other, use the script code in the main SWF file to Control the playback of these small advertisement f...

Abstract

The invention relates to a method for converting video files into SWF files, comprising the following steps: extracting related parameter values of a source video file, and calculating related parameter values of a main SWF file required to be generated on the basis of the extracted related parameter values; converting the source video file into at least one FLV file; generating at least one sub SWF file according to the calculated related parameter values of the main SWF file, and respectively embedding the FLV file into each sub SWF file; generating one main SWF file according to the calculated related parameter values of the main SWF file, and adding the at least one sub SWF file into the main SWF file frame by frame; adding play rules into the main SWF file; and storing and outputtingthe main SWF file. The invention also discloses a system using the method. By utilizing the method and the system of the invention, not only the standard format of Flash files are not destroyed, but also only one SWF file is generated no matter how long the video file is, thereby breaking through the limitation of the SWF file on the length of the video file.

Description

technical field [0001] The invention belongs to the field of computer applications, and more specifically relates to a method and system for converting a video file into a SWF file. Background technique [0002] Currently on the Internet, the main body of the Flash format commonly referred to is divided into SWF (ShackWave File) file format and FLV (Flash Video) video format. Compared with ordinary video formats, FLV video format is a streaming media format that supports online playback. SWF file format is a playable media file that contains some videos such as FLV, scripts, pictures, animations, sounds, etc. Company Flash Player to play the implementation. [0003] In recent years, the demand for Flash files on the Internet has always been on the rise. Among them, the Flash format (SWF files and FLV videos) dominates the online video market, with a share as high as 81%. In China, 98% of Internet-connected computers have installed Flash Player; According to iResearch, fro...
