Abstract

The invention discloses a desktop video encoding control system based on content analysis, and relates to a device for sending a screen image video. The desktop video encoding control system comprisesa screen video acquisition module, a screen image content analysis module and multiple paths of video encoders, wherein the screen video acquisition module is configured to acquire a screen image ofthe device in real time; the screen image content analysis module is configured to carry out analysis on each frame of acquired screen image; the multiple paths of video encoders are configured to carry out video encoding on the acquired screen image in parallel or as required; and the device is configured to select a video output by one of the multiple paths of video encoders according to an analysis result for sending. According to the invention, a bran-new system framework is used, the image is analyzed on the basis of desktop contents, and according to the analysis result, a code rate is distributed and a reference frame for transmitting the video is selected, so that the desktop video encoding control system can be more flexibly applicable to various different network conditions, thecontents are more reliably shared and transmitted, and use experience of a user is ensured.

Description

technical field [0001] The invention relates to the technical field of communication and video processing, in particular to a desktop video coding control system based on content analysis used in video conferencing and other occasions. Background technique [0002] Internet-based video communication technology is widely used in business and personal situations such as video conferencing and other work and life applications. In these applications, it is often necessary to capture the screen displayed on the computer desktop, and then use video coding technology, such as H.264, H.265 and other international standards, to encode the captured screen data, and then transmit it in real time. [0003] In the process of encoding computer desktop screen images using video encoding technology, the existing video encoding transmission system does not analyze the contents of the desktop screen images, but takes the entire image as input and submits it to the video encoder for processing...
