html5-video

问题 I am serving video's in a webview in Android using Appcelerator Titanium. On iOS this works like a charm. But on Android this gives some problems. It goes wrong the second time an activity is opened with a webview that holds a html5 video element. Steps to reproduce: (Also see this youtube video: http://www.youtube.com/watch?v=0MpSpfJNyOk ) The first time opening a video/activity with html5 video it shows the video and I am able to play it. When I close the window/activity and open a new

问题 I have encountered a strange issue. I have a webpage where users can upload a video and the video plays on a HTML5 video (using "autoplay" in the tag) on a small screen after the upload is completed. Also, after the upload, the user can click a button to save what they have uploaded, whereby the folder containing the video is renamed. However, if they click save button too quickly, IIS gives an error that the folder is unavailable (for renaming). But if they wait about 20 seconds into the

问题 I am making an app with HTML5 video along with a canvas drawing on top of it (640x480 px). The objective was to record the canvas drawing along with the encoded video to produce it as a single video. I was able to do all these using FFMPEG. But the problem I am facing is, when the HTML5 video is running it takes around 50% of my CPU. Since drawing on canvas is also demanding CPU, the browser freezes after certain time and the CPU usage for that tab on chrome is showing continously > 100. I

问题 Basically what I'm trying to do is make the video redirect to a different web page after it's finished playing (very similar to what YouTube uses for Playlists). I've tried doing a bit of research before asking this type of question but nothing seems to be working out for me. Here's the code: <video id="example_video_1" class="video-js vjs-default-skin" controls preload="auto" width="854" height="480" poster="images/thumbnailbackgrounds/AE-DageSide.jpg" data-setup='{"example_option":true}'>

问题 I actually cannot believe I couldn't find an answer to this as it appears to me as if it should be a common problem - am I using the wrong terminology? However, I am looking for a way to switch the audiotrack of the video that is being sent to be played on chromecast. More precisely I'm talking about a multitrack video File embedding two audio lines (mkv-format). I've not found any possibility to do this using the (Android) SDK, nor could I change it using JavaScript on the Receiver App

问题 I'm looking for a creative way to replace an HTML5 video with an image under a few circumstances. Don't want to deal with flash or anything like that to make the video work... would rather give them an image. Give them the image if: If the desktop browser doesn't support HTML5 video If the user is mobile Seems simple... especially by using Modernizr for css tags with display:none; if the video isn't supported ... so here's the caveat: The HTML5 video is edge to edge and centered to the screen

问题 I can't figure out the following problem: I use HTML 5 video on my web site. For crossbrowser support, I keep video in "mov" and "ogv" formats, so that Firefox can play it. In ./config/initializers/mime_types.rb I have the following code: Rack::Mime::MIME_TYPES.merge!({ ".ogg" => "application/ogg", ".ogx" => "application/ogg", ".ogv" => "video/ogg", ".oga" => "audio/ogg", ".mp4" => "video/mp4", ".m4v" => "video/mp4", ".mp3" => "audio/mpeg", ".m4a" => "audio/mpeg" }) It works on my local

问题 I'm looking for a solution for embedding video and audio in html. The new videotag supports .ogg and .mp4, but is there a fallback solution for .flv and other formats? For example, if I want to embed an .ogg, it will check whether or not html5 is supported, if not, it uses the fallback. If I want to embed a .flv is uses the fallback. 回答1: html5 tag supports a fallback to any element, if the browser cannot interpret the video tag. here s a quick example for a fallback to a flash-file. <video
