We want to display a fixed image at the end of a video playback. The referenced url is the video address stored on the server. Which one is appropriate? The video tag has events about the end of playback. How to change the video cover at the end of playback? I have tried to write a hidden image by default. When the video playback ends or pauses, the picture is displayed, but the image is always pressed under the video control, and z-index is not allowed. How to solve this problem, so that the video is paused and the screenshot at the end of the video also stays here by default?
