JwPlayer6Windows7Creating Your Own Accessible HTML5 Media Player. This was my first in a series of blog posts on creating an accessible HTML5 audio player. If youre more interested in outcome than process, see the article Putting it all together Accessible HTML5 Audio Player with Yahoo Media Fallback. HTML5 introduces the lt audio and lt video elements, which enable web browsers to natively support media without requiring users to download and install a plug in. It also greatly simplifies the code required to add media to a web page. For example, heres all you need to add Man With Small F The Inaccessible PDF Song to your HTML5 website feel free I dont mind. Sorry, your browser does not support HTML5 audio. In the above example, the lt audio element includes two attributes controls Tells the browser to display the default media player. This is necessary in order for keyboard users to access the controls more on that in a moment. This example also includes two lt source elements, which is necessary since browsers dont currently support a common file type, either for video or audio. Finally, this example includes fallback content, which is delivered to users whose browsers dont support lt audio. But this is only an example Dont do what I did. Telling the user Sorry, your browser does not support HTML5 audio is not good fallback content. Instead, we could provide a link to download the media file, or could add an lt object element that delivers an alternative accessible Flash player more on that later too. HTML5 lt audio and lt video have been written about extensively elsewhere. My favorite all encompassing resource is the article by Simon Pieters on the Opera Developer Blog titled Everything you need to know about HTML5 video and audio. In fact, that article was the launching point for everything youre about to read here. My focus in this article is on audio, since my goal is to provide an accessible audio player for my music blog.

Current versions of most major browsers support lt video and lt audio at some level. Internet Explorer will support these elements in the next major release IE9. Unfortunately, none of the current browser implementations are fully accessible by keyboard nor screen reader. Keyboard Accessibility. Heres the status as of August 2. Opera 1. 0. 6 is the only browser that supports keyboard access to individual player components the playpause button, seekbar, mute button, and volume control. This is true in both the Windows and Mac versions. However, there is also one quirk in both versions users can tab to the seekbar slider, but they cant operate it, at least not using any obvious keys I tried all four arrows, plus Page Up and Page Down. Otherwise all controls are fully accessible by keyboard, including interestingly the volume slider, which can be controlled using up and down arrows. Firefox 3. 6 Windows and Mac has partial keyboard support. The player can receive focus in the tab order, and once it has focus users can toggle playpause with the space bar, and can seek forward and backwards using the left and right arrows. There is no apparent way to access the Mute button or volume control with keyboard alone. However, if the user mouses over the mute button, the volume control is displayed and at that point it can be adjusted up or down using the arrow keys. Interestingly, the volume can only be adjusted with keyboard its not accessible to mouse usersSafari 5. Mac and 5. Windows both have the same problem Users can tab to the player, but once it has focus they cant access any of the individual controls, nor can they trigger the play event. Its also worth noting that Safaris player in either browser doesnt provide a volume control, so if users want to adjust multiple audio sources independently of the main system audio, theyre out of luck in Safari. An obvious beneficiary of independent volume controls is screen reader users, particularly important on a Mac since Safari is the likely browser of choice for Voice. Over users. Chrome 5. Safari, is 1. 00 inaccessible by keyboard. Screen Reader Accessibility. JAWS 1. 1 does not support lt audio yet. It just skips the audio player entirely. According to TPGs new AViewer as used in Firefox, MSAA is exposing the lt audio element as a nameless, valueless, descriptionless node with rolegrouping and statefocusable. Bmw Dvd Unlock Software. That could surely be more explicit. However, the individual player components are being exposed with much more useful information. The Play button has rolepush button and namePlay or Pause, depending on its state the slider has roleslider, and a name that includes the elapsed time and total duration and the Mute button has rolepush button and nameMute or Unmute, depending on its state. I would think this would give screen readers enough information to work with. In fact, NVDA in Firefox does recognize lt audio and renders it meaningfully. It reads the buttons with their current name as exposed by MSAA Play, Pause, Mute, or Un. Mute, and these buttons work perfectly. As for the slider, NVDA reads the current position as a percentage value. It also sounds a tone that gradually ascends in frequency as the audio loads, and stops when the file is fully loaded. However, once the slider has focus I couldnt figure out a way to control it anyone else There is also another quirk Before playback begins, the position of the slider is announced as 0. I think most users would be content if that value was rounded to the nearest second i. On a Mac, Voiceover in Safari announces the lt audio element as Audio Element Controller Toolbar. The user can access the individual components with Voice. Over command Control Option Shift Down arrow. Voice. Over announces that there are four items on the toolbar, and each is clearly named theres a Play Button, Mute button, Back 3. Seconds Button, and the X seconds slider where X is the current position in seconds. Each of these controls is operable. Medical Terminology Made Easy Fourth Edition Essential Cell. So, things are currently looking pretty good for Voice. Over users, and not too bad for NVDA users in Firefox. However, since there are quite a few users who fall outside of these groups, Im convinced that we need an interim solution The Solution A Custom HTML5 Media Player. See the sample custom player on my HTML5 Audio Test Page. Until browsers and assistive technologies provide better, more accessible support for HTML5 lt audio, we need to build our own player controls. Fortunately HTML5 media elements include a powerful API that allows us to access and control their inner workings using external controls. My HTML5 Audio Test Page compares the default controller with a custom built accessible one. I commented the code on that page extensively, so I wont go into all the technical details here, but here are a few highlights on how I built the accessible controller First, I removed the controls attribute from lt audio. Without this attribute, the default player is not displayed. Then, I added an empty lt div, to which I would add the custom controls using Javascript. By building it with Javascript, I can test whether the browser supports lt audio. If it does, the custom controls are added to the DOM. Otherwise, users get the fallback content contained within the lt audio element. Heres how I tested for lt audio support.
