Why does HTML5 video with very large h.264 encoded mp4 (with +faststart, ie metadata at beginning), take ages to load?

阅读更多关于 Why does HTML5 video with very large h.264 encoded mp4 (with +faststart, ie metadata at beginning), take ages to load?

问题 The video is rendered with ffmpeg with the "faststart" flag added meaning the metadata should be at the start of the file, and the server appears to be handling partial content requests correctly, so why does it need to have downloaded so much of the video before the player becomes enabled and can play the video? I am testing it in Google Chrome. Once the player becomes enabled I can seek around to various points in the video pretty instantly and see the new partial content requests being

Anythingslider html 5 video autoplay

阅读更多关于 Anythingslider html 5 video autoplay

问题 please i need your help folks! I'm using Anythingslider to slide between HTML5 video and other content, but when I add autoplay attribute in video tag, Anythingslider plays just audio. 回答1: Are you sure the video is not hidden behind another element? Play with the z-index as the video should be visible. I've had a few issues with this in the past, such as the video flickering in and out of visibility on scroll. I ended up playing the videos in a light box since anything slider would leave the

阅读更多关于 Pause jQuery Cycle with Video.js

问题 I have a jquery cycle slider that I need to pause either when a video is played or when a slide is reached that displays a video. (Either of those options is fine, but I could not figure out how to pause a slide with a certain class or id.) I am using video.js to display videos. What is happening is when I press play the video starts playing, but when I move the mouse off the video it automatically goes to the next slide. If I click on the pager thumbnail it stays paused, but if the slideshow

Autoplay background video in Chrome Autoplay Policy

阅读更多关于 Autoplay background video in Chrome Autoplay Policy

问题 So in the latest chrome apparently the Autoplay Policy has been changed so this in turn breaks every site that has a video background that should autoplay I am wondering if anyone has any smart work arounds that could "solve" the issue? (I believe a button or "enter page" solution would be a terrible way of a work around especially for a background video) Here is what you get now in the console if a user doesn't interact with the document: Uncaught (in promise) DOMException: play() failed

html5 video streaming

阅读更多关于 html5 video streaming

问题 I am working to stream a video screencast on our cakephp site using mediaViews and html5. I am using videojs for the player and am running into a few problems: Will not stream in safari/ipad/iphone (I have it converted into an mp4) Does not allow the viewer to skip to the middle of a video in any browser. They must watch the video straight through start to finish, which is not ideal. Is not falling back to the flash object for browsers that don't support html5 It currently streams correctly

Why are videos played before inserted into DOM?

阅读更多关于 Why are videos played before inserted into DOM?

问题 Why does executing something like the following var videoBg; videoBg = $('<video autoplay>'); videoBg.attr({ 'src': 'http://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4', 'height': 360, 'width': 640 }); cause the video to be played before being inserted into the page's DOM? Isn't the idea that the user should not be able to notice elements unless they are somewhere in the DOM? What's the difference between an object being visible and an object being audible? 回答1: Makes sense to me. It's being
