Video processing method, system, device and medium

The invention discloses a video processing method, system and device and a storage medium, the method processes a video through a Linux architecture, the Linux architecture comprises video frame processing equipment, a plurality of video frame processing application programs and a video frame buffer area, any video frame processing application program corresponds to one video frame processing equipment, and the video frame buffer area corresponds to the video frame processing equipment. The method comprises the following steps: acquiring a current video frame and detecting a first operation request sent by current video frame processing equipment; in response to the first operation request, putting the current video frame in the video frame buffer area into a buffer area output queue and waking up the current video frame processing application program, so that the current video frame processing application program performs one-time preset processing on the video frame; generating a processed first video frame
