Abstract

The invention provides a video processing method and device and electronic equipment, belongs to the technical field of video rendering, and solves the problem that the CPU occupancy rate is too high in video rendering in the prior art. The video processing method comprises the following steps: acquiring to-be-rendered video data; calling the VAAPI to decode the to-be-rendered video data to obtain decoded video memory image data; calling the VAAPI to generate a display surface based on the video memory image data; calling the EGL API to create an EGL display object; generating a texture object by using the EGL display object; calling the EGLAPI to generate a renderable texture object according to the display surface and the texture object; and rendering the renderable texture object by using a renderer to obtain rendered video data.

Description

technical field [0001] The present invention relates to the technical field of video rendering, in particular to a video processing method, device and electronic equipment. Background technique [0002] The existing security industry client monitoring preview video and playback video are limited to the Windows platform, and the display experience of high-definition video relies on the Linux module provided by Microsoft. However, with the gradual prevalence of localized Linux in recent years, there are more and more demands for high-definition video display based on the localized Linux platform, and the QT framework, as the carrier of the cross-platform software interface, has always used YUV (a color coding method) to display video Direct rendering, and YUV data belongs to memory data. Direct rendering of YUV memory data has the following disadvantages: the conversion of GPU (graphics card) memory data to CPU-processable memory data, and the need for system display modules, ...
