Abstract

The invention provides a video optimization processing method for a remote desktop. The method comprises the steps of registering a coder-decoder corresponding to a video decoding format supported bya video processing unit when initialization of a preset multimedia vide processing tool is started; judging whether the video decoding format corresponding to the registered coder-decoder is matched with a coding format; if yes, calling the video processing unit to decode video frame data; and returning a corresponding file descriptor; and transferring the file descriptor to a processing interfaceof a bitmap hardware acceleration module, thus allowing the bitmap hardware acceleration module to perform image conversion on the decoded video data. The invention also provides a video optimizationprocessing device for the remote desktop. According to the method and device provided by the invention, the technical problem that the video playing experience is poor due to the fact that the embedded platform of an existing ARM-SOC framework uses a software processing mode to decode and perform image conversion is solved.

Description

technical field [0001] The invention relates to the technical field of computer video processing, in particular to a remote desktop video optimization processing method and device. Background technique [0002] In the field of computer desktop virtualization, the RDP protocol (Remote Desktop Protocol, Remote Desktop Protocol) is widely used, and various cloud computing terminals provide remote desktop clients supporting the RDP protocol. For cloud computing terminals, in order to reduce costs, most of the terminal hardware uses SOC (System On Chip, System on Chip) processors based on ARM architecture (ARM is a processor architecture); in terms of software, Linux system plus Use the open source FreeRDP protocol stack to implement the RDP client program. [0003] However, the RDP client program implemented by the open source FreeRDP protocol stack has problems such as large operation delay, video playback freezes, and poor playback experience. Among them, the video playback ...
