Embodiment Construction

[0032] In order to make the present invention more comprehensible, a preferred embodiment is described in detail below with accompanying drawings.

[0033] Such as figure 2 Shown, the present invention is based on the improvement that the DirectShow framework of multimedia redirection technology carries out, and server end includes Source Filer (source filter), Transform Filer (transmission filter), Render Filer (rendering filter), and client end includes There are Source Filer (source filter), Transform Filer (transmission filter), DirectVobSub Filter (subtitle processing filter), Render Filer (rendering filter), video files and subtitle files are located in the server, through Source Filer (source filter) to obtain the video file in the server, then find the subtitle file by the file path of the video file and transmit it to a temporary directory of the client, and simultaneously transmit the video file to Transform Filer (transmission filter) for parsing. The video data i...

Abstract

The invention provides an external subtitle redirection method based on DirectShow. The method includes the steps that step1, a subtitle file is obtained from a service side; step2, the subtitle file is transmitted to a client side; step3, a DirectVobSub Filter is loaded into a video playing link of the client side, and the directory path where the subtitle file is located is obtained through an interface of the DirectVobSub Filter; step4, the time stamp of each frame of video data in a video file of the client side is adjusted, and after subtitle data are added into the video data according to the time stamps, the adjusted video data are played through the video playing link of the client side. The invention further provides an external subtitle redirection system based on DirectShow. The problem that in a cloud computing environment, when a multimedia redirection technology is used for watching high-definition videos, external subtitles can not be loaded is solved.

Description

technical field [0001] The invention relates to the technical field of multimedia redirection, in particular to a method and system for redirecting subtitles based on DirectShow. Background technique [0002] DirectShow is a set of development kits provided by Microsoft for streaming media processing on the Windows platform. It is a set of application systems based entirely on COM (Component Object Model, that is, Component Object Model). The COM component of Filter (filter), each Filter completes certain functions on the data stream. [0003] Existing technologies such as figure 1 As shown, the multimedia redirection technology uses the DirectShow framework. Both the server and the client include Source Filer (source filter), Transform Filer (transmission filter), Render Filer (render filter), and the video file is located in the server In the terminal, the video file in the server is obtained through the Source Filer (source filter), and the video file is transmitted to ...
