[0028] Please refer to figure 2 , figure 2 A flowchart of a video processing method provided by an embodiment of the present invention is shown. The video processing method includes the following steps:

[0029] Step S101, using the EGL interface to establish a video buffer, so that the original video captured by the camera device can be buffered in the video buffer.

[0030]In the embodiment of the present invention, OpenGL refers to a professional graphics program interface that defines a cross-programming language and cross-platform programming interface specification, and OpenGL ES may be OpenGL of the embedded device 100 . EGL is the interface between OpenGL ES and the underlying Native platform windowing system. The video buffer can be an off-screen surface Surface, and the video buffer is a buffer that does not display the original video but can render an image. At the same time, the video buffer can be directly switched to the display screen of the embedded device...

Abstract

The invention relates to the field of embedded technologies, and provides a video processing method and device, an embedded device and a storage medium. The embedded device comprises an OpenGL and anEGL interface and is provided with a camera shooting device. The method comprises the following steps of acquiring an original video acquired by the camera shooting device; storing the original videointo a pre-established video buffer area; acquiring a first image from the video buffer area, wherein the first image is any frame of image in the original video; and utilizing the OpenGL to process the first image in order to obtain a processed original video. According to the embodiments of the invention, the original video is stored in the pre-established video buffer area, so that the OpenGL can directly process the original video in the video buffer area, the time delay of video processing is eliminated, and the video processing efficiency can be remarkably improved.

Description

technical field [0001] The present invention relates to the field of embedded technology, in particular to a video processing method, device, embedded device and storage medium. Background technique [0002] Due to the limited performance of embedded systems, dedicated video processing chips are mostly used in the field of embedded real-time video processing to meet the needs of embedded real-time video processing. However, the development of these dedicated video processing chips is difficult and costly. OpenGL ES is a set of professional graphics program interfaces for embedded platforms, which can well reflect the capabilities of GPUs, and the development difficulty is lower than that of professional video processing chips. However, OpenGL ES is mainly used for hardware acceleration of graphics rendering, and the internal display storage cannot be directly used by developers. This will increase the time delay of real-time processing and reduce the efficiency of real-time ...
