problem description
when using the vue development community website to draw up user browsing data browsing headlines or watermelon videos, there is a preview of the video or picture when browsing the app on the mobile end. Click on the preview image to browse the video or picture directly. Why the app I made has to wait until the video has been downloaded before it can be played, while theirs is when you click to play. How do you play a little data and request a little data? is it the front-end technology or the server-side technology?
