VideoJS m3u8 example

Here is an example of how to use video.js with HTTP Live Streaming (HLS) with an m3u8 playlist file: < !doctype html> <html> <head> <link rel=”nofollow” href=”” rel=”stylesheet”/> <script src=””></script> </head> <body> <video id=”my_video_1″ class=”video-js vjs-default-skin” controls preload=”auto” width=”640″ height=”264″ poster=”my_video_poster.png” data-setup=”{}”> <source src=”″ type=’application/’/> </video> </body> </html> via

How to use HLS (HTTP Live Streaming) with Amazon CloudFront

I have a mp4/h.264 video that is a around 300mb. I would like users to be able to watch it on both desktop browsers and mobile devices. I have the video file stored on Amazon S3. I have two cloudfront sources enabled – one for download and one for streaming. I know I can use something like VideoJS to play the file with the ‘video/mp4’ source being the “download” cloudfront source which, I believe, plays while the file is being downloaded – I think this is called “progressive download” but it is not true streaming. I also realize that I can use something like JWPlayer and the “streaming” cloudfront source to give users on a desktop device, or a device that supports flash, the RTMP streaming experience. The problem I’m facing is poor performance on iOS devices – especially ones with limited bandwidth. From what I’ve been reading HTTP Live Streaming (HLS) seems to be the only “streaming” protocol that iOS devices really support. And as far as I can tell, Amazon Cloudfront only natively offers RTMP streaming of uploaded mpeg/h.264 files (not HLS). Amazon has a Live Smooth Streaming tutorial for use with Amazon CloudFront which appears to be, in a nutshell, a Windows IIS server running Adobe Flash Media Server and pushing out the HLS stream via Amazon Cloudfront. So, my questions were: If I want to push H.264/mpeg4 files “streaming” to iOS devices or HTML5 players, is the “right” way to do this to use HLS? Can … Continue reading

Using VideoJS with YouTube

I have been using VideoJS for some streaming videos and mp4 videos, but also wanted to pull YouTube videos into the player along with the other videos I had on the site. First of all, the working example. Then, the list of problems ;) VideoJS and Youtube Example How to replicate the Youtube and VideoJS integration: First, clone or download this fork of videoJS and build it. Next, place this in your webpage’s <head> (needs to be there to work with older browsers). Also fix the odd character after the href in the first line (sorry about that) and make sure the path points to the correct location for the files. <link href≠”/video-js/video-js.css” rel=”stylesheet” type=”text/css”/> <script src=”/video-js/video.js”></script> And then place this in your document’s <body>: <video id=”example_video_1″ class=”video-js vjs-default-skin” controls preload=”none” width=”640″ height=”360″ data-setup='{“techOrder”:[“youtube”,”html5″],”ytcontrols”:false}’> <source src=”” type=’video/youtube’ /> </video> There is also an example file in the dist directory which will only be created after you “build” the fork you have cloned from github. VideoJS and Youtube Problems With Integration I tried simply giving VideoJS the URL to the YouTube video but that didn’t workout so well. Here are a few things that might help you out with playing You Tube videos in Video JS: There is a pull request for changes that would allow VideoJS to work with YouTube. A few problems with it are: Has not been pulled in Both the Video JS maintainer and the pull requestor have become busy with other projects so it might not … Continue reading

How to Select a jQuery UI tab with Javascript

The documentation for jQueryUI tabs is a bit cryptic. It was not immediately clear how to Select a jQuery UI tab with Javascript, but I got it working with this little bit of code: $( “#tabs” ).tabs( ‘select’, “#profile” ); #profile is the id of the tab you would like to select, and #tabs is the element you set up the tabs on by calling $( “#tabs” ) You may also have to use jQuery instead of $ if you have noConflict mode enabled, the tabs need to be initialized first (as previously mentioned), and it is possible you will need to put all this info inside the ‘jQuery document ready’ wrapper: jQuery(function($){ $( “#tabs” ).tabs( ‘select’, “#profile” ); });

Recently I was checking out the Better WP Security plugin for WordPress and noticed that the plugin comes with a cool blacklist of useragents from (btw that website seems to have a lot of great info on fixing hacked wordpress sites). Anyhow I found that after installing the plugin my .htaccess file was updated and included a new section to block malicious IPs and user agents. The list looks like this:

What is

I just saw an ad for and visited their site and watched their video. They appear to be most similar to dropbox with some resemblance to sendbigfile / kicksend and also some functionality of Google Docs. From their homepage (without watching the video) I had a hard time understanding what they did. They have a cloud based service and a fairly simple API that you can use to connect with it. It seems interesting but I’m not sure it will gain enough support to be around in the long run. Hopefully they will – competition is good.
