Embodiment Construction

[0017] Such as figure 1 As shown, a remote desktop proxy video recording method based on RDP protocol includes the following steps:

[0018] The mstsc client authorizes to access the rdp server through the rdp proxy;

[0019] Obtain the protocol flow of the mstsc client operation process;

[0020] Create real-time desktop buffer based on desktop size and bitmap pixels;

[0021] Analyze the operation of the mstsc client in the protocol stream and update it to the desktop buffer. The operation of the mstsc client includes obtaining bitmaps, bitmap caching, text events and mouse events;

[0022] Transcode the contents of the real-time desktop buffer into a video stream through a video transcoding program, and save it to a video file;

[0023] The mstsc client access is over and the video file is saved.

[0024] Preferably, the method further includes the step of downloading the video file, and the saved video file can be played and downloaded.

[0025] Preferably, the storage format of the v...

Abstract

The invention relates to a remote desktop proxy video recording method based on a RDP protocol. The method comprises the steps as follows: an mstsc client accesses a rdp server; a protocol flow of anmstsc client operating process is acquired; a real-time desktop buffer area is built; operations of an mstsc client in the protocol flow are analyzed, and updated to the desktop buffer area; the content of the real-time desktop buffer area is transcoded into a video flow, and stored into a video file; and the mstsc client ends accessing, and the storage of the video file is completed. According tothe method provided by the invention, the operations of the mstsc client are recorded and stored via the desktop buffer area, and the operations are transcoded into the video file, so that the user is convenient to play and download, a player can be freely selected for playing the video file formed after transcoding, the playing effect is good, the phenomenon that the image is blocked is avoided,the user is convenient to perform operations such as fast forward and backspace, and the convenience is provided for the user operation.

Description

Technical field [0001] The invention relates to the technical field of remote desktops, in particular to a method for remote desktop proxy video recording based on RDP protocol. Background technique [0002] In the prior art, when using the RDP protocol to remote desktop proxy video recording, the RDP protocol performs proxy operation and maintenance. The protocol data between the local desktop and the remote desktop is acquired by the RDP proxy and recorded as a protocol log, which is played back through a specific client However, this method has poor replay log effects and tool limitations, so that some operations cannot be implemented, which brings inconvenience to users. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a remote desktop proxy video recording method based on the RDP protocol, so as to improve the effect of replaying logs and facilitate user operations. [0004] In order to solve the above technical proble...
