Abstract

Embodiments of the present invention provide a method, device, system, and computer-readable medium for video redirection. By intercepting video data frames and video data frame decoding instructions sent by a video player, the intercepted video data frames and video data frames are decoded. The instruction is sent to the client to realize video redirection, so that the client decodes the video data frame according to the video data frame decoding instruction. The video data frame is obtained by demultiplexing the loaded video file by the video player; when implementing video redirection, it saves server computing resources and network transmission bandwidth, and does not depend on a certain video player, and makes full use of the client's computer resources.

Description

technical field [0001] The present invention relates to the field of information technology, in particular to a video redirection method, device and system. Background technique [0002] With the continuous development of computer technology, remote desktop has become a popular technology. The remote desktop technology transmits the content displayed on the screen of the remote server to the local client for display by logging in to the remote server. Remote desktop application does not only refer to remote screen display, but also includes remote video transmission. [0003] In the prior art, when using a remote desktop video player to play a video file, in order to save remote server computing resources and network transmission bandwidth, a Microsoft-based DirectShow framed Media Player , after loading the video file through the video player on the remote server, the DirectShow The Filter in intercepts the undecoded video data in the video file, and the DirectSh...
