Abstract

The embodiment of the invention discloses a multi-video-card video data processing method and device, and aims to solve the technical problems of lag, tearing, excessively-low frame rate and the like under a multi-screen and multi-video-card situation due to playing of local video files with a common player in a work station in current large-screen display applications of monitoring rooms and meeting rooms. In the embodiment of the invention, the multi-video-card video data processing method comprises the following steps: determining widths and heights of output screen resolutions of video cards; creating corresponding D3D equipment and buffering areas according to the widths and the heights of single logical screens formed by the video cards; and copying decoded video data into the buffering areas through the D3D equipment in order to uniformly display the decoded video data.

Description

technical field [0001] The invention relates to the technical field of signal processing, in particular to a multi-graphics video data processing method and device. Background technique [0002] Video card (Graphics card) full name display interface card, also known as display adapter, is one of the most basic configuration and most important accessories of the computer. As an important part of the computer host, the graphics card is a device for digital-to-analog signal conversion by the computer, and it undertakes the task of outputting display graphics. The graphics card is connected to the computer motherboard, which converts the digital signal of the computer into an analog signal for display on the monitor. At the same time, the graphics card still has image processing capabilities, which can assist the CPU to work and improve the overall operating speed. Graphics cards are very important for those engaged in professional graphic design. Graphics chip suppliers for c...
