html5-video

问题 I'm trying to load a mp4 video stream from Django to Vue.js. I followed the solution here and got a byte string via my axios API which I concatenated to data:video/mp4;base64, , and then binded it to the video tag's :src property, but the video is not displaying. Is this the correct way to stream videos from Django 3 to Vue.js? What am I doing wrong? Api.js code snippet: import axios from 'axios' export default () => { return axios.create({ baseURL: `http://127.0.0.1:8000/`, headers: {

问题 I am using Chrome 81, latest. I am including a <video> inside a <div> container which is set to flex-grow: 1. The idea is there is a header, and the bottom of the page fills to be the video, which will be contained the best possible. The strange problem is that when the window shrinks vertically and when the full picture size fits the window a scrollbar appears and grows until the size of the header is contained by the scrollbar. Once the header is contained in the scrollbar, the video also

问题 If the user wants to stop the HTML5 media, for example by clicking “pause” native control button, we get "onpause" event. At the same time, if media element reaches the end of the specified fragment, it triggers the same "onpause" event automatically. Is it possible to separate one from another? In JQuery style, <video id="video1" src="url/video.webm#t=10,20" controls></video> <script type="text/javascript"> $(window).load(function () { $('#video1').on("manualpause", function () { alert("you

问题 I have a strange problem. On a website for my client, I'm showing some mp4 files using the HTML5 video element. The videos that are visible on the page while loading do show up on mobile devices without any problems. When I try to change the source of a video element (after an AJAX request), the video element shows a black screen. The new video source I changed could be exactly the same as one that was already shown on page load, but after updating the src parameter it just won't show..

问题 I have an array of video elements that I wish to play at the same time. The only way I've found online that I could do this would be to use new MediaController(); but that doesn't seem widely/if at all supported. What I was expecting to do was: var videos = document.querySelectorAll('video'); var mc = new MediaController(); video.forEach(function(el) { el.controller = mc; }); mc.play(); The only way I've found to do this is doing a forEach on the array and playing them one after another, but
