The first tag we will look at is the <AUDIO> tag. This new tag allows us to embed audio content in a variety of formats that the browsers will understand. As of now the browser file format support is somewhat spotty, so it’s worth checking the chart at w3c.org and enabling multiple file formats inside the audio tag.
Lets do a quick example of the <audio> tag:
<source src="song.ogg" type="audio/ogg" />
<source src="song.mp3" type="audio/mpeg" />
Your browser does not support the audio element.
The control GUI isn’t standardized, so you may see some issues in formatting when you view with diffrent browsers, but on the whole this process is much easier.
If you wanted to have the audio play automatically, loop, or do something when it is buffering you can do that quite easily.
<audio src=”song.ogg” autoplay loop>Your browser does not support audio tags</audio>
You’ll note that there are no = signs or quotes — we don’t need them anymore! HTML5 eliminates the need for boolean attributes to have = or “”‘s. Simply put the name of the desired boolean property and it will be interpreted by the browser as being set to true. We’ll discuss this syntax change at length in the next article.
Below is the table of currently supported audio formats and the browser support for each:
|Format||IE 8||Firefox 3.5||Opera 10.5||Chrome 3.0||Safari 3.0|
According to this chart from W3C (link here, we will need at least two file formats of our audio file in order to cover all major browsers. For the example I chose Ogg and Wav formats.
<audio loop autoplay>Your browser does not support audio tags.
<source src="song.ogg" type="audio/ogg" />
<source src="song.wav" type="audio/mpeg" />
This will allow the browsers to select the correct file type it needs with only two additional lines of code!The <VIDEO> tag:
<video src="movie.ogg" controls="controls">
your browser does not support the video tag
We can see that the formatting is exactly the same as the audio tag. Like audio, we can also define multiple file sources in order to supply the correct format. All major web browsers support Ogg video and/or MP4.
<source src="movie.ogg" type="video/ogg" />
<source src="movie.mp4" type="video/mp4" />
oncanplaythrough — play the element as soon as it is buffered.
oncanplay — play when able, even if it might have to stop for buffering.
preload — buffer the element and wait for play.
autoplay — Play as soon as page loads, don’t wait for buffering
onend — do something when the element is done (like play the next video in a set)
onemptied — do something if the buffer is used up and no more buffer remains (like from disconnections)
onerror — pretty self-explanitory. Do something if any errors in playing the element are encountered
A full list of HTML5 events can be viewed here: http://www.w3schools.com/html5/html5_ref_eventattributes.aspThe <object> Tag:
The <object> tag takes over the loading of applications into the web browser from the <applet> tag. It makes it easier for both programmers and machines alike to read HTML markup and determine the values and settings being passed into the loaded application. Take this example of an embedded object:
<object classid="xxxxxxxx-xxxxxx" id="example">
<param name="code" value="test.class" />
<param name="test2" value="testing" />
<param name="fname" value="Alan" />
<param name="lname" value="Jenner" />
<object> tags have multiple ways to declare the source of the target application or plugin: URLs and windows registry items with the “classid” option, or three other src-related attributes. It doesn’t matter which you use as long as you follow this style:
<param name=”[code/src/data]” value=”[URL]”>
You can define code, src, data, or any of the other parameters in the <object> tag itself or within <param> elements.What's with the weird tags?
You may be asking at this point why the <object> tag is structured this way. It’s structured with these extra tags to make it easier for machines to read the code in websites, something that will be needed for the semantic web, a revolution in how the web works similar to web 2.0.
Tim Berners-Lee (the creator of the World Wide Web) defines the semantic web thusly:
I have a dream for the Web [in which computers] become capable of analyzing all the data on the Web – the content, links, and transactions between people and computers. A ‘Semantic Web’, which should make this possible, has yet to emerge, but when it does, the day-to-day mechanisms of trade, bureaucracy and our daily lives will be handled by machines talking to machines. The ‘intelligent agents’ people have touted for ages will finally materialize.
In the next article, I will go into the semantic web in depth and show examples of the syntactical changes from HTML4 to HTML5 that will facilitate the development of the semantic web.
Fact is, enterprises have significant legacy voice infrastructure that’s costly to replace with pure IP solutions. How can we bring this analog infrastructure into our shiny new cloud applications? There are proven methods to bind both legacy voice applications and traditional PSTN audio into cloud-based applications and services at a carrier scale. Some of the most successful implementations leverage WebRTC, WebSockets, SIP and other open source technologies. In his session at @ThingsExpo, Da...

Today we can collect lots and lots of performance data. We build beautiful dashboards and even have fancy query languages to access and transform the data. Still performance data is a secret language only a couple of people understand. The more business becomes digital the more stakeholders are interested in this data including how it relates to business. Some of these people have never used a monitoring tool before. They have a question on their mind like “How is my application doing” but no id...

The Internet of Things (IoT) promises to simplify and streamline our lives by automating routine tasks that distract us from our goals. This promise is based on the ubiquitous deployment of smart, connected devices that link everything from industrial control systems to automobiles to refrigerators. Unfortunately, comparatively few of the devices currently deployed have been developed with an eye toward security, and as the DDoS attacks of late October 2016 have demonstrated, this oversight can ...

More and more brands have jumped on the IoT bandwagon. We have an excess of wearables – activity trackers, smartwatches, smart glasses and sneakers, and more that track seemingly endless datapoints. However, most consumers have no idea what “IoT” means. Creating more wearables that track data shouldn't be the aim of brands; delivering meaningful, tangible relevance to their users should be. We're in a period in which the IoT pendulum is still swinging. Initially, it swung toward "smart for smar...

We are always online. We access our data, our finances, work, and various services on the Internet. But we live in a congested world of information in which the roads were built two decades ago. The quest for better, faster Internet routing has been around for a decade, but nobody solved this problem. We’ve seen band-aid approaches like CDNs that attack a niche's slice of static content part of the Internet, but that’s it. It does not address the dynamic services-based Internet of today.
