However, this is intended to be used together with the new HTML canvas tag for drawing of 2D and 3D objects, CSS3 animation and transformation capabilities, as well as browser support for SVG (scalable vector graphics) and web fonts. HTML5 relies mainly on JavaScript to provide rich animations and interactivity. One aspect of the comparison between Flash and HTML5 that seems to have been left outside is the animation capability. You will need to implement advanced scripts to detect browser capabilities and then use the best presentation option. However, you cannot yet depend only on the new HTML5 video and audio support.
It is a good idea for developers to start using the new audio and video support in HTML5 browsers, specially for iPhone and iPad users. On top of that none of the browsers (except for Opera) currently support all the video and audio functions (controls) specified in HTML5. The situation with audio is similar in terms of the scope of the specification, different formats available and the support by major browsers. Without any definition on streaming we are left to whatever mechanism browser and server developers want to support. Most online video is currently encoded using the H.264 codec, and many devices support hardware decoding which greatly improves performance and battery life.Īnother important aspect that was left out of the standard was streaming. Some browsers support one or another, and only Chrome has decided to support both. So far the two main choices are H.264 and Ogg Theora formats.

Since W3C (the governing body of the HTML standard) decided not to specify a standard video format, each browser developer is free to choose what video format to support. In order for a browser to play video it needs to include a video codec. Any help greatly appreciated.HTML5 allows embedded video to play natively in the browser.

What is the best and most pragmatic workaround given that Apple are almost certain not to budge on this issue?įrustratingly, the application code works excellently on other devices.Why not allow pre-load of audio when these devices are connected to WiFi - there can be no reasonable justification for it to be turned off in this scenario.
This does make some sense, but to actually switch off a feature of HTML5 audio that my application requires without giving an option for users to re-enable it seems madness to me, particularly as ALL of my users will be running the web app when connected to WiFi which would incur no cellular charges anyway. The reasoning given is that this is done to avoid use of cellular network data which could be costly. Unfortunately, preloading of HTML5 audio is disabled in Safari mobile (iPad / iPhone) - see this article from Apple. The audio clips need to be pre-loaded at the start of the experiment so that they play virtually instantaneously when called from JavaScript / jQuery. It is an online psychological experiment that has around 50 short audio clips within each experiment run. I have been writing a HTML5 / Javascript web site designed to run across all manner of devices.
A question about pre-loading of HTML5 audio being disabled on mobile iOS devices running Safari.
