html5 css3 javascript video formats browser support

shared by Vernon Fowler on 05 Feb 13 - No Cached
  • The solution for now is to produce your videos in multiple formats. Table 1. Browser support by video format Browser MP4 WebM Ogg Internet Explorer 9 Yes No No Firefox 4.0 No Yes Yes Google Chrome 6 Yes Yes Yes Apple Safari 5 Yes No No Opera 10.6 No Yes Yes Note: For the latest compatibility information, always check the CanIUse website.
  • A more robust way to create the fallback is to use a JavaScript utility like Modernizr to evaluate the browser's capabilities and then dynamically write the video and source tags or embed the Flash video player using SWFObject.
  • Tip 3: The source tag should always include the "type" attribute with the correct MIME type value. You may need to add an .htaccess file to your server to define the MIME types as well. Check out the Video for everybody article for more tips on MIME types.

  • Tip 2: The video tag includes a range of parameters that you can use to configure the video. See the Mozilla article Using HTML5 audio and video for more information.
  • Tip 1: The Adobe Media Encoder does not currently export video to Ogg or WebM format. You can use the Firefogg add-on for Firefox to encode video to Ogg Theora format, or you can use Miro Video Converter to encode video to WebM or Ogg Theora format.

  • an :invalid pseduoselector that can be used to select all elements with validation errors
  • only give an error for the first field
  • showing the users only the first error message is bad

  • Browsers that support HTML5 form validation have one thing in common; if a <form> is submitted and has errors on multiple fields, the browser will only display the first error to the user.
  • instead of listening for submit on the <form>, I instead listen for a click on the <input type="submit">. Since the user is also able to submit the form pressing enter in text inputs, I attach a keypress listener to them to ensure the same logic runs.
