Use the poster attribute in HTML to set an image to be shown while the video is downloading.
You can try to run the following code to implement poster attribute −
<!DOCTYPE HTML> <html> <body> <video width = "300" height = "200" poster = "https://www.tutorialspoint.com/images/logo.png" controls> <source src = "/html5/foo.ogg" type = "video/ogg" /> <source src = "/html5/foo.mp4" type = "video/mp4" /> Your browser does not support the video element. </video> </body> </html>
