The invention discloses a desktop screenshot data processing method and device for an interactive classroom, equipment and a medium, and belongs to the technical field of computers. The method comprises the following steps: initializing desktop screenshot to obtain a first frame of screenshot image which succeeds in screenshot; mapping the first frame of screenshot image to a CPU from a video memory of a GPU, copying the first frame of screenshot image to a cache of the CPU, and reading screenshot data from the cache of the CPU for the GPU to perform initial frame coding; identifying whether the current frame desktop screenshot succeeds or not; and if the screen capture of the current frame fails, reading the screen capture data from the cache of the CPU for the GPU to encode the current frame. According to the technical scheme, the problems of long data processing time and large memory occupation caused by multiple mapping of the screenshot data can be avoided, and the stability of the screenshot frame rate
