html5-video

问题 I was working on a custom component and stumbled upon this strange behavior. Basically, it is possible to play a video file without adding a <video> element to the DOM at all. const video = document.createElement('video'); video.src = "https://upload.wikimedia.org/wikipedia/commons/transcoded/c/c6/Video_2017-03-19_23-01-33.webm/Video_2017-03-19_23-01-33.webm.480p.webm"; function start() { if (video.paused) { video.play(); console.log('paused', video.paused); } } <div><button onclick='start()'

问题 HTML5 has <video/> element that downloads video from server, decodes it and renders. Often if not always they use hardware accelerated decoding (if available). Is it possible to access just decoding functionality? The reason is that I'm using custom streaming protocol and so on client side I have encoded video stream that I need to decode and render. Pure JavaScript implementations of video decoder are not applicable unfortunately as they cannot provide sufficient performance. I'm interested

问题 I'm new to Angular 2. If I have a video tag, like : <video width="480" height="480" autoplay></video> And a javascript example snippet to open the camera stream : var video = document.getElementById('video'); if(navigator.mediaDevices && navigator.mediaDevices.getUserMedia) { navigator.mediaDevices.getUserMedia({ video: true }).then(function(stream) { video.src = window.URL.createObjectURL(stream); video.play(); }); } In Angular 2 + Typescript I suppose I can access the video tag like :

问题 I'm using jwplayer to play videos in html5 mode. Videos are in mp4 format. What I'm seeing in the network tab are bunch of network requests with 206 status (partial download). So my understanding is -> video is just being streamed in partial chunks, 1-2 Mb each. But can those chunks be cached in the browser? Currently I'm seeing video just being re-streamed every time... 回答1: With reference to this answer: Yes, 206 responses are cacheable. This is also explicitly stated in RFC 7233, section 4

问题 I have a video and I need to capture 3 images from it, at different time. Time is not random, I have to take images at specified time (13:10:02, 13:10:03, 13:10:04). The images should be displayed on the page when I access the page, not when I click a button or something like that. Until now I tried with an example that I found on the internet, but on this example, the image is displayed after a button was clicked, and I don't know how to give a specified time. <video controls> <source src=
