问题 I have embedded DASH videos in webpage using <video> tag. This content has multiple audio tracks. I want to support audio track change. I used audioTracks[i].enable feature to select a audio track. But the audio track is not changing. if (selected == i) { audioTracks[i].enable = TRUE; } Is this the right way ?

问题 Playing a 3gp file with HTML5 does not work. I have Firefox 16 and Chromium Version 22 and the result I got is the following: No video with supported format and MIME type found.

问题 I'm working on implementing a fallback mechanism for the HTML5 video player. I've got a way to replace it with the swfobject Flash player, but how should I detect if any issues have developed? In other words, if we use the following list of error events that can be thrown, which one should trigger the Flash player replacement? Or should we simply do a replacement if any error is thrown? Also, where should the onError handler be called? I'm thinking on the video tag, but want to make sure.

问题 Can you use javascript to detect if the video is playing? paused? or stopped? I know VLC under browsers can do this, but don't know how to do it without VLC? 回答1: You can query the media object to get the playback state: http://www.w3.org/TR/2011/WD-html5-20110113/video.html#playing-the-media-resource "A media element is said to be potentially playing when its paused attribute is false, the element has not ended playback, playback has not stopped due to errors, the element either has no

问题 I'm still trying to understand angular... Basically, I have an html5 video and I want to listen to the onloadeddata event (http://www.w3schools.com/jsref/event_onloadeddata.asp). This is what I have: html: <video autoplay="autoplay" loaded-data loop style="display: none;"> <source src="videos/example.mp4" type="video/mp4"> <source src="videos/example.ogg" type="video/ogg"> </video> directive: angular.module('myApp') .directive('loadedData', function () { return function ($scope, $element) {

问题 I'm writing a web app that serves H.264 encoded MP4 video. In Chrome and Safari, it does this via an HTML5 video tag. In order to control access to these videos, their contents are served via PHP using a really simply mechanism: header('Content-type: video/mp4'); readfile($filename); exit; No matter what I do, the videos will not stream. Additionally: If I change the source code to serve the files directly, using the same video tag but linking to an Apache-served copy of the video with no PHP

问题 Just wondering if anyone knows any tricks to getting regular html content (mainly an img tag) to display on top of a video (via the video tag)? 回答1: As others have intimated it's very easy to position HTML elements on top of VIDEO elements using absolute positioning. The challenge comes when you try to capture events on them in the iPhone, iPod and possibly older Android phones that don't play video assets inline on the page (as opposed to in a thin native playback client) since in those

问题 For some reason I'm sure the folks at DivX think is important, there is no straightforward way to prevent their plugin from replacing all video elements on your page with they fancy logo. What I need is a workaround for this, telling the plugin to skip some videos, i.e. not replace them with their playable content. 回答1: I got around this by putting an empty HTML 5 video tag, then putting in the video source tags in a JavaScript function in the body onload event. The video then comes up in the
