The present invention provides a method and device for generating a video preview image, a storage medium, and an electronic device. The method includes: when a user uses a video player to play a local video, using a packet reading thread to extract key image frames from the local video , saving the extracted key image frames to the first buffer queue; the decoding thread decodes the key image frames read from the first buffer queue, and saves the decoded image data obtained by decoding to the second buffer queue, The disk saving thread converts the decoded image data read from the second cache queue into a video preview image. By using the packet reading thread to extract the key image frame from the local video, using the decoding thread and the storage thread to process the key image frame, the video preview image of the local video is obtained, and the video content is displayed to the user through the video preview image, so that the user can understand the video in advance Play content, you can quickly and accurately find the content you are interested in, so that the user experience is better.
