Embodiment Construction

[0022] see figure 1 and figure 2 Shown, the method for audio-video redirection under the VDI environment of the present invention, comprises the steps:

[0023] Step 1: The user remotely logs in to the virtual desktop in the VDI environment through the client, and performs video playback operations;

[0024] Step 2: The server side establishes the playback link. After the data source and separator are established, the redirector is preferentially matched and loaded to complete the establishment of the playback link; the priority matching and loading of the redirector specifically refers to: using the directshow framework The mechanism sets a priority for each filter, and the redirector is set to the highest priority, so it is always loaded and matched first;

[0025] The data source: refers to audio and video data sources, including files and network data;

[0026] The separator: responsible for parsing media files, and separating audio and video data streams therefrom;

Abstract

The invention provides a method for carrying out audio/video redirection in a VDI (Virtual Device Interface) environment, which comprises the following steps that: a user logs in a virtual desktop by a client and carries out video playing operation; after a data source and a separator are established, a server side preferentially matches and uploads a redirector; when starting to play a video, the redirector carries out selective processing on video data; if a coded format is an original video coded format, the data is fed into a data compressor and the data is compressed into a media format which can be decoded by the client; if the coded format is a decodable format supported by the client, the data is transmitted to a client communication module by a server side communication module; if the coded format is not one of the two coded formats, the data is rejected to receive, a server side decoder is uploaded and the data is subjected to decompression processing; and a client play assembly displays and plays a played image on the virtual desktop. According to the method provided by the invention, an audio/video redirection technology is more universal for supporting the multimedia coded format and the play fluency of the standard/high definition video with the definition of at least 720P is promoted.

Description

【Technical field】 [0001] The invention relates to the technical field of computer audio and video, in particular to a method for redirecting audio and video integrated with software and hardware 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] The audio and video redirection technology in the VDI environment is to redirect the intercepted server-side audio and video data to the client, and then the client performs decoding and rendering to complete the playback. The application of audio and video redirection technology makes audio ...
