问题 I have a web application where I play back video. I am considering using the HTML5 <video> element and have determined it will allow me to meet all of my requirements except one: allowing the user to take a snapshot of the current video frame and save it as a raster image format (i.e. JPG). For this requirement I have not found a solution, and any guidance on this matter would be greatly appreciated. To help answer the question here are more details. I will download the video files from a

Javascript to stop HTML5 video playback on modal window close

I've got a html5 video element on a modal window. When I close the window the video continues to play. I'm a total newbie to JS. Is there an easy way to tie a video playback stop function to the window close button? Below is my html page: <!DOCTYPE html > <html lang="en"> <head> <meta charset="utf-8" /> <title>Modal Test</title> <script type="text/javascript" src="jquery.js"> </script> <script type="text/javascript"> $(document).ready(function(){ $("#showSimpleModal").click(function() { $("div#simpleModal").addClass("show"); return false; }); $("#closeSimple").click(function() { $("div

How do I detect if the HTML5 autoplay attribute is supported?

How do I best detect whether a browser's HTML5 video element supports autoplay? On current iOS Safari, for example, autoplay is disabled . Update: I now designed the web page in such a way that it works irrespective of whether autoplay is supported. Now when the page is loaded an initialization video is shown. On an iPad, the user is presented with a big play button. Once playback has been triggered, the video is hidden. Afterwards, playback of the video player can be controlled from JavaScript, which is what I actually need. A little late to the party, but the accepted solution seems outdated

rounded corners on html5 video

Is there a way I can cut off the corners of my html5 video element using the CSS3 border-radius attribute? Check out this example . it's not working. Wreeecks Create a div container with rounded corners and overflow:hidden. Then place the video in it. <style> .video-mask{ width: 350px; border-radius: 10px; overflow: hidden; } </style> <div class="video-mask"> <video></video> </div> It works in Firefox as long as you set the appropriate 180px height for the 320px width video (16:9 aspect ratio) - otherwise the curved borders aren't visible because they're outside the frame of the video. There

Image placeholder fallback for HTML5 Video

由 ▼魔方 西西 提交于 2019-11-27 18:46:16
I'm using the following code to implement an HTML5 video on a page <video autoplay> <source src="/resources/video/product-hero.mp4.mp4" type='video/mp4; codecs="avc1.42E01E, mp4a.40.2"' /> <source src="/resources/video/product-hero.webmhd.webm" type='video/webm; codecs="vp8, vorbis"' /> </video> This works great, embedded on my page in FF, Safari, and Chrome. What I'd like, since this video has no controls, and is mean to be embedded in the page with no borders (white BG in the video) is to have an image appear in place of the video. I'd like to have an image as the fallback if the video can't

HTML5 and Javascript to play videos only when visible

由 ℡╲_俬逩灬. 提交于 2019-11-27 18:37:26
I am interested in setting up an HTML page with multiple video clips such that each video clip plays only while visible and then pauses when out of view. I have found this great example of how this can be implemented with one clip, but I have been unable to modify the code to work with multiple clips. Perhaps I need to convert this code into a function for easy re-usability? Here is what I have so far (JS Bin linked above modified for 2 clips instead of one). This code seems to work for only one of the two clips. <!DOCTYPE html> <html> <!-- Created using jsbin.com Source can be edited via http
