Webpage flash video redirection method in VDI environment

Abstract

A webpage flash video redirection method in a VDI (Virtual Desktop Infrastructure) environment comprises the following steps: analyzing webpage text data and acquiring both a file of a Flash video player on a present webpage and parameters used during video play; intercepting a webpage HTTP (Hyper Text Transport Protocol) request and acquiring a video request of the present webpage; analyzing a request data packet and reversely positioning to a Flash control issuing the requests through the group of requests; sending the Flash video player embedded into the webpage to a client side and dynamically building a Flash video play environment the same as the present webpage on the client side according to the structure of the present webpage; generating a network request by the operating Flash video player on the client side; and sending corresponding video streaming to the client side for play by a VDI server which receives the video request from the client side. By adopting the webpage flash video redirection method provided by the invention, the burdens of both the VDI server and the client side are greatly reduced and the quality of watched videos is improved.

Description

【Technical field】 [0001] The invention relates to the technical field of computer audio and video, in particular to a method for redirecting web page flash video in a VDI environment. 【Background technique】 [0002] VDI, the English full name is Virtual Desktop Infrastructure, that is, virtual desktop infrastructure. Instead of configuring each user with a desktop PC running Windows XP or Vista, it virtualizes your desktop by running Windows XP on a server in the data center; Client Computing Protocol for Home PC) is connected to virtual desktops, and users access their desktops as if they were accessing traditional locally installed desktops. [0003] With the promotion of cloud computing technology, more and more VDI protocols are used. Playing video in a VDI environment has always been a difficult problem to solve. Video playback in a VDI environment is limited by the VDI protocol on the one hand, and the network bandwidth on the other hand, which makes the VDI protoco...

AI Technical Summary

Problems solved by technology

[0005] Although using the above method can solve the problem of unsmooth playback of webpage Flash video to a certain extent, it also has many negative effects

[0006] 1. After the server finishes decoding the original video data, it needs to re-encode the decoded video data, which takes up a lot of server resources;

[0007] 2. When the client performs full-screen playback, the data to be encoded by the server increases with the increase of the current display resolution. When the client connects with a larger resolution, the server's CPU resources will not be able to afford the demand for compressed images;

[0008] 3. When the client performs full-screen playback, because the data that the client needs to decode increases with the increase of the current resolution, the client also consumes a huge amount of CPU resources, which eventually leads to the client being unable to afford the decoding requirements ;

[0009] 4. Since the image is processed by a compression algorithm, when using the above method to watch the video remotely, the video quality will be greatly reduced compared with the original video quality
