问题 All of my research and effort has been hitting a wall so far in this regard: Is there any way to make video autoplay on Safari in iOS currently? Some have mentioned video transcoding or using playsinline (which works on Android), but nothing has worked for iOS / Safari. 回答1: I believe the following is still the current picture for iOS: elements will now honor the autoplay attribute, for elements which meet the following conditions: elements will be allowed to autoplay without a user gesture

问题 I've created a webCam Stream with navigator.getUserMedia({ "video": true }, function(stream){ videoTag.src = window.URL.createObjectURL(stream); videoTag.play(); } Can I access the MediaStream object in stream in global scope?* (something like navigator.getAllMediaStreams[0] ) *edit: ...without adding logic to the getUserMedia function. My problem case is a qr-decoder-library, that gets the stream for me and I don't want to change the third party code 回答1: There is no list of active media

问题 I created a web application using Java and html5. I have uploaded few videos in tomcat server war folder.Say my war file name is "web". Then my videos are inside /opt/Apache/WebApps/web/videos/sample.mp4". I am using html5 video tag for playing the videos.Most of the video size is more than 100mb. My video tag is like <video src="/videos/sample.mp4"></video> Whenever I played the video, automatically download inside our temp folder of my c drive. My system RAM size is 128mb. So when I watched

问题 I am displaying a video via HTML tag <video> . I want to supply a small and a large video depending on the resolution of the users screen. A small screen should then only download the small video. It is no longer possible to do this with the media attribute directly in HTML. The JavaScript solution based on matchMedia I tried instead is not working. I tried the following JavaScript code using matchMedia that I found in a video by Google (https://youtu.be/j5fYOYrsocs?t=356): HTML: <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: {
