How to Embed Video/Audio on HTML5 Page

In HTML 4.x, the only way to reliably embed video on a web page so that all users can see it regardless of browser or operating system, is to use Flash which is fully compatible with FLV converter. This requires the Adobe Flash plug-in and a combination of the <object> and <embed> tags.

In a long time to come, you may have to provide both HTML5 and Flash to be compatible with all web browsers. But you could learn how to embed video/audio in HTML5 now and when the HTML5 time comes, you can switch to it easily. As the proverb goes: Chance favors only the prepared mind.

This article will take a look at what might be the most-hyped part of the HTML 5 specification - the audio and video tags.

Using HTML5 Video Tag
Famous video sharing sites such as YouTube is chomping at the bit to use the HTML5 video tag. It will greatly seize a chunk of web size. Here's the code to embed a video in HTML 5:

<video src="path-to-html5-video.mp4"></video>

Really simple, right? But you will embed video something like below because not every browser can recognize the <video> tag.

<video src="path-to-html5-video.mp4" controls>
<object width="550" height="400">
<param name="movie" value="path-to-fallback-flash.swf">
<embed src="path-to-fallback-flash.swf" width="550" height="400">
</embed>
</object>
</video>

This method lets the browser choose the video or flash to play, with their default video player. So your video will be played in different style player, maybe the Safari style or Chrome style. Another free option is to use the third-party HTML5 video player like VideoJS, FlareVideo, JW Player, etc. Here VideoJS is recommended for it is free, full screen, and consistent style in all HTML5 browsers.

Using HTML5 Audio Tag
The code looks very similar to <video>. However, the Mozilla only supports Ogg Vorbis files, while Safari can handle pretty much anything QuickTime can.

<audio src="path-to-html5-audio.ogg" autoplay>
Sorry, your browser does not support the <audio> element.
</audio>

Similar to the <video> tag, the same Flash solutions would give you near universal support for today's crop of browsers.

Why There Are So Many Image Formats?

It certainly is true that there are lots of different image formats on the web -- Just at How Stuff Works, we use 6 different image formats:

  • GIF files
  • JPEG files
  • Animated GIF files
  • MPEG files
  • Shockwave files
  • NxView files

The two most common by far are GIF and JPEG files. Both of these formats encode static (as opposed to animated) bitmap images.

In a bitmap image, the image file has to define the exact color of every pixel in the image. For example, imagine a typical bitmap on the web that is 400 by 400 pixels. To define this image, you would need 24 bits per pixel for 160,000 pixels, or 480,000 bytes. That would be a huge image file, so both the GIF and JPG formats compress the image in different ways.

In a GIF image, the number of colors is reduced to 256 and then "runs" of same-color pixels are encoded in a color+numberOfPixels format. For example, if there are 100 pixels on a line with the color 41, the image file stores the color (41) and the length of the run (100). This makes a GIF file great for storing drawings that have lots of same-color pixels, like this image from How Microprocessors Work:

This is a 500 by 500 pixel image, but instead of taking 750,000 bytes it takes only 9,000 bytes to store it as a GIF.

A JPG file uses a much more complex technique to compress images, like photographs, where the color of every pixel is different. A GIF file creates a perfect reproduction of the original, while a JPG does not. See Question 289 for some details.

An animated GIF is a sequence of GIF files all bonded together and displayed one after the other. With enough panes, you can get very realistic animations. However, the size of the file is the sum of the GIF files used to create the sequence, and that can add up quickly. There are a number of animated GIFs in How Engines Work. All of them are large compared to a static GIF. For example, this animated engine GIF is about 75,000 bytes:

An MPEG file uses a complex algorithm like a JPEG file does -- it tries to eliminate repetition between frames to significantly compress video information. In addition it allows a soundtrack (which animated GIFs do not). Because a typical sequence has hundreds or thousands of frames, file sizes can still get quite large. How Helicopters Work contains a dozen or so MPEG files.

Shockwave provides a vector-based animation capability. Instead of specifying the color of every pixel, a Shockwave file specifies the coordinates of shapes (things like lines, rectangles, circles, etc.) as well as the color of each shape. Shockwave files can be extremely small. They allow animation and sound. The images are also scalable -- because they are vector-based, you can enlarge the image and it will still look great. This page contains two great animated Shockwave files that are both about 10,000 bytes in size.

Finally there are the NxView files (You can see a good example on How Gas Turbine Engines Work). These are vector-based 3D files that allow user interaction. You can rotate and zoom in on a 3-D object in any way you like. This is essentially the Shockwave idea taken to 3-D. The files are suprisingly small (100K to 200K) for the amount of detail they contain.

You can see that each file format has a set of features and advantages that make it the best choice in a given situation. That is why there are so many image formats!

Will Skype be another Microsoft license gotcha?

After Microsoft acquired Skype beforehand this ages for $8.5 billion, best of the questions revolved about how Skype's IM, articulation and video calling appearance will fit into Microsoft action articles such as Outlook and Lync.

But an appropriately important catechism is: How will Skype fit into your action license? And will you end up advantageous for it alike as you don't use it?

"It's aloof one added asset that Microsoft will array into an all-embracing action agreement," says Jeff Muscarella, and controlling of IT at NPI, a consulting close that advises action IT buyers.

Muscarella compares Skype to Microsoft's 2006 accretion of Softricity. This paved the way for App-V, an appliance virtualization technology that is formed into MDOP (Microsoft Desktop Optimization Pack), Microsoft's apartment of on-premise PC administration accoutrement for barter with an action agreement.

"You accept to accept an EA to use MDOP," says Muscarella. "But best of our barter don't use MDOP and they don't appetite it. But they are advantageous for it. And they accept to altercation with Microsoft to unbundle it."

Like best big tech vendors, Microsoft is authoritative an advancing advance into the adaptable and unified communications spaces, with Windows Phone 7 and Lync, respectively. The Skype accretion is a abundant way to annular out the UC appearance aural Office, says Muscarella, but he adds that abounding big companies already accept UC articles in place, whether it be through Cisco WebEx or Microsoft Lync.

"If you're affective bottomward the UC aisle with some of the added players like Cisco, there will be UC overlap and you won't allegation Skype," he says.

"Skype will apparently be allotment of an Office and Lync CAL [client admission license], so barter will accept to ask themselves whether or not they allegation Skype. If the acknowledgment is no, they allegation to apperceive if they'll be able to unbundle it from the CAL. Microsoft will apparently accomplish that difficult."

Muscarella addendum that action vendors like Microsoft, Oracle and SAP generally advance aback aback barter try to unbundle genitalia of an EA.

"You go aback to Microsoft with a account of 10 requests and they'll say no to eight of them," he says.

NPI has assassin above Microsoft advisers who accept the development of thecomputer application giant's action agreements and apperceive the appropriate argot to use. For instance, abounding barter are not acquainted of the chargeless testing and QA (quality assurance) casework accessible to them if they are associates of the MSDN or TechNet programs.

"There is a lot accounting in accomplished book and you accept to go to Microsoft and adduce affiliate and ballad from the user rights area of the EA," says Muscarella. "If you don't do that, or don't apperceive area to accretion those EA clauses, Microsoft is blessed to allegation you for aggregate you do."

It's not bright yet how Microsoft will fit Skype into its action artefact band or its action agreements. Muscarella predicts that Skype will abide to be chargeless for consumers and baby businesses, but warns enterprises that Skype may be snuck into a aback added big-ticket CAL, alike if it's a dollar actuality and a dollar there.

"If you accept a lot of desktops - 500 or 1,000 or added - the authorization costs will add up quickly."

Despite the boilerplate absorption the accretion accustomed and Skype's acceptance with consumers, it still ends up actuality aloof addition technology that Microsoft can cycle into an EA to potentially appoint added or accidental accuse on a business.

"It's potentially a authorization antic like annihilation else," says Muscarella."You accept to accomplish abiding you are not affected into a one admeasurement fits all archetypal and action with Microsoft to carve the EA bottomward to what you need."

HTML5 VS Flash, what is your choice?

HTML5's been pitted against Flash as the savior of web video since the release of the iPad, on which you can't play any Flash contents. There are those that suggest that HTML5 will one day supplant/replace Adobe Flash. On that day, you could finally enjoy web video on your iPad (and more mobile devices). I am only a website owner, rather than a programmer. What can I do in this revolution (is it)? HTML5 is rapidly growing as a new standard of online video technology, and we need to be prepared in advance to accommodate it. It is still early to say that HTML5 will replace Flash totally, Html5 doesn’t provide all the features and functionality that Flash does today, so we’ll have to consider our choices wisely.
 
HTML5 VS Flash
Before comparing HTML5 to Flash, we need to know what exactly they are, right?
Flash: It's a multimedia platform used to add animation, video, and interactivity to web pages by Adobe (formerly Macromedia Flash). As far as you know, Flash is frequently used for advertisements and games. More recently, it has been positioned as a tool for "Rich Internet Application (RIA) ". Flash is the most widely used content delivery methodology up to date. By the way, The Microsoft counterpart of Flash is SILVERLIGHT.

HTML5: It's the next awaited version of HyperText Markup Language (HTML) which is expected to bring about a radical change in the client side web coding. However, when people refer to HTML5, they usually mean the combination of HTML as a markup language, CSS which specifies how it is rendered, and the javascript code which manipulates the HTML and CSS dynamically.

HTML5 not only has the standard text elements, but also <video> elements which embeds the video and <audio> to element to embed the audio, which was brought to web browser by Canvas - a more relevant method compared to Flash. Below is the general Flash to HTML5 comparison.

Why choose Flash
Good to great web presentation
Excellent Flash player penetration
Browser independent
AS3 is a strong typed language

Why choose HTML5
Doesn't require a plug-in
The best bet for animated content on mobile devices
Fast bitmap rendering
Fast JavaScript render speed
Great open source initiatives trying to push Canvas further

HTML5 Will Beat Flash, But Not Now.
So, there are both advantages and disadvantages of HTML5 and Flash. But in my opinion, HTML5 improves interoperability and reduces development costs by making precise rules on how to handle all HTML elements, and how to recover from errors. It has more opportunities to win the war. HTML5 will replace Flash and SILVERLIGHT eventually, maybe 5 years, maybe 10 years. Do note that both Adobe and Microsoft are giants; you don't know what they will do to affect the result. Only one thing is sure: HTML5 and Flash will go together for a long time to come.Flash is offering value to a lot of people and will not disappear overnight.

Now stay far away from the debate of replacement of HTML5 to Flash. You need to move your business on. But the situation is now or will be like this: Many people use the web browsers that don't support HTML5 like Internet Explorer 6,7,8, while others have upgraded their browsers to which well support HTML5. How would you do?

The mix solution like HTML5 video player seems to be unavoidable. And keep your eyes on HTML5 is also necessary.

Simply burn CD/DVD with Nero

Every time you download something from internet to burn it to CD or DVD then I recommend you download the ISO image. A disk image is a file that contains everything we see on a CD, as an exact copy in a single file. The problem is that many people download images of the discs and then not know what to do. Today I will explain how to burn an ISO image with Nero, a free DVD burner.

What usually happens is that you save the file to disk as it was downloaded, and then noticed that serves no purpose. What you need to do is a process leading to view the content of the image, and then to record it.


Nero is a program for recording CDs and DVDs with multiple options, and a large number of applications.
Nero Express is probably the most used application in the Nero suite.. Using Nero Express you can record in a simple and fast data, music, and video or slide presentations.
Nero Express has an attractive interface and simple, the process of recording is done through a wizard that makes things much easier for less experienced users.
For people who do not want to eat the head is the Nero Express 6 which is very easy to handle. Recommended for people who do not know much about it, with this just click and two clicks and you're recording what you want.


I'll explain how to burn these files four simple steps, Based on Nero Express


First step: Once we enter the program also confirm that the reader is directed, and then select the option "Disc Image or Saved Project", which will allow us to burn the ISO image without problems.

Second step: We select the folder where the file you want to record, select it and open it.

Third step: Now we must select the recording options as we commonly do. We recommend that you choose a speed of 8x and it took a little while more, the quality is superior.

Bing能在2012年篡位取代Google么

我们都知道Google是目前搜索引擎领域毫无争议的王者,不过最近的数据表明微软全力打造的Bing很可能在不久的将来对Google形成挑战,甚至有可能取代Google成为搜索引擎新一代的No.1。

据国外媒体报道,截止2011年3月,在Google以64.62%的市场份额稳坐搜索引擎美国市场头把交椅,但在过去的6个月中,微软Bing获得了令人惊异的快速增长,如今Bing已经占据了美国搜索引擎市场30%的市场份额,如果按照这个增长速度发展下去,Bing迟早将对Google的地位形成严重威胁并有可能篡位成功。

Mashable网站根据目前的发展态势又制作了一张预言图表,从图表中我们可以看出,如果二者继续按照目前的比率发展的话,在2012年1月份,Bing将迎来与Google的交叉点,随后将取代后者称为市场NO.1搜索引擎。当然这只是媒体记者一厢情愿的分析而已,实际情况是任何公司在快速发展初期都会保持一个较高的增长比率,而在一定规模后就会遇到增长瓶颈,所以我们可以断定,Google与Bing的战争必将是一场旷日持久的大战。

月末效应


每个月的月初,大家使用移动设备上网的行为比较频繁,但是到了一个月的下旬,每月订的流量使用完了,所以出现了下降的曲线,这个就是月末效应哈。
月初是访问量高峰,之后一路下降,到了15号又出现一个访问高峰,月末达到最低值。

用户在搜索什么

平时看着大家坐在电脑前或者拿着手机移动设备上网,你知道大家在网上都干了些什么么?用户使用互联网搜索什么信息呢?

这幅图可以说明大家使用移动互联网搜索行为,用户搜索等。可以看出,大部分客户上网是娱乐,比如小说,图片,音乐,视频等。
