Today most of the browsers use a flash plugin to play the videos.This works pretty well but Flash unfortunately requires a lot of computing power.This would be an issue if the system has a low end configuration Hence the new web standard HTML5 is trying to change that.
HTML5 has been designed with audio and video codecs which take less processing power its equivalent Flash player which rules the browsers audio and video plugin.As with most new technologies, things are not always clearcut.
HTML5 is the largest ever opensource project undertaken by W3C.Hence we can expect some terrific improvements in processing efficiency from HTML5,it should not be assumed that it will completely replace Flash or even have a significant impact,especially on rich web content. Flash still has many advantages such as.
• Better sub pixel resolution and anti aliasing
• It’s good excellent developer tools (far more extensive than HTML5)
• Flash has a vast array of good looking and impactful fonts
At this point, graphic artists and game developers still feel that flash is the best. Though they might certainly like the idea of being able to operate with less computing overhead, they want to get the most control and ability to generate outstanding results that flash would provide them while HTML5 may or maynot deliver.
However for many simpler video playback application such as in YouTube,metacafe HTML5 has the ability to quickly surpass Flash as the video/audio player of choice in browsers. At this point, the development of the YouTube HTML5 supported player is still in its early phases and a lot more tweaking and refinement must be done.
Right now It needs more support to work properly with other browsers and extensive testing to work out instability and incompatibility issues.However since it’s on an open platform, there are many people working through these issues so it is just a matter of time.
But many developers feel that this process might take years as there are still many issues to work out. As few specifications stated in HTML5 are controversial.
And another bottleneck is HTML5 is not compatible with all browsers and many users are resistant to changing to another browser.
As far as an average user is con concerned if a browser works well he doesn’t bother to switch over to new technology or a new browser in such a scenario HTML5 has a daunting task ahead to replace the position of flash.
For example, Internet Explorer is largely criticized for its instability and security flaws. Yet many people steadfastly hold on that browser and are very reluctant to change to something like Firefox or Chrome.
So be aware that even with the potential efficiencies which HTML5 can bring, don’t expect rapid deployment or changes away from Flash.
