Watching online videos on mobile phones is in a trend as the development of mobile device. However, as we know, different mobile devices use different codec standard because they are in different OS. Put it simply, iPhone only can play the online videos in MP4 format, while Andriod mobiles can play online videos in FLV format only. We could think if there is a format can be supported by both systems, the mobile video websites will attract more visitors.Then, HTML 5 video has come out.
What is HTML5?
HTML5 is a language for structuring and presenting content for the World Wide Web, and is a core technology of the Internet originally proposed by Opera Software.It is the fifth revision of the HTML standard (created in 1990 and standardized as HTML4 as of 1997)and as of January 2012 is still under development. Its core aims have been to improve the language with support for the latest multimedia while keeping it easily readable by humans and consistently understood by computers and devices (web browsers, parsers, etc.). HTML5 is intended to subsume not only HTML 4, but XHTML 1 and DOM Level 2 HTML as well. –

What is HTML5 Video?
HTML5 video is an element introduced in the HTML5 draft specification for the purpose of playing videos or movies, partially replacing the object element. HTML5 video is intended by its creators to become the new standard way to show video online,[citation needed] but has been hampered by lack of agreement as to which video formats should be supported in the video element. –

As easyhtml5video.com says, HTML5 is the fastest growing web development trend and HTML5 video as a part of HTML5 becomes the new natural way to show video online. iPad, iPhone, Android, all new browsers declare the support for HTML5 video. It’s great, but what is the usual route to create HTML5 video? First you need to find converters and make three versions of your video – .
OGG,
MP4,
WebM. Then, to provide the compatibility with IE and old browsers you add a fallback Flash version of your video with Flash video player. And finally, you extract an image for poster and write batch lines of code to combine all of it…
What are the codecs for HTML5 video?
This is the codec supported by Apple and Microsoft. It is a licensed codec that provides good quality video and small file sizes. There are a lot of programs available for both Mac and Windows that will encode in
H.264 video.
Where the problem comes in is that this codec is not free. MPEG LA, the owner of the
H.264codec, has said they wouldn’t charge royalties for internet video that is free to end users in perpetuity. But what does that mean? They may charge browser makers and video editing software makers to put the codec into their products, or they could take it right to the video creators (although this is unlikely). Ultimately, if the MPEG group starts charging anyone for the license of this software, we will be paying for it at some point through increases to the price of software we purchase or the loss of support in browsers and other devices.
Ogg/Theora is a free open standard for video encoding. It generates high quality videos with comparatively larger file sizes. Plus it is a lot harder to find tools to convert to
ogg/Theora. And in some cases they only convert the video, and not the video and audio.
Ogg/Theora is free software, so many people are comfortable using it because they are not concerned that they will be charged a license fee some day in the future. As such, we can expect that the cost of this codec will remain free.
WebM uses the VP8 codec that is owned by Google. It has high video quality, but it can take a lot longer to encode a video in
WebM than in
H.264. While Google claims that
WebM has the highest video quality of all the web codecs, most independent sources find that either
H.264 is slightly better or there is very little difference between the two. The problem is that it can be very difficult to encode, especially compared to the many free and commercial tools available to encode
H.264.
The
WebM codec is free and open source, so it should remain free to use. However, the underlying codec is owned by Google. And their position on open source could change in the future. Ultimately, most people are assuming it won’t, and so this codec will remain free.

Gradually, HTML5 video will be the first chosen for websites’ builders. As the software pioneer, sothink has been dedicated in developing the products in the advanced technology, and we’d like to let you know that our
HTML5 video converter will be released in the near future; it is the video tool that can help you convert videos to HTML5 formats for publishing. Please keep an eye on our website for the latest news!
