Secure context

This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.

The Geolocation API allows the user to provide their location to web applications if they so desire. For privacy reasons, the user is asked for permission to report location information.

WebExtensions that wish to use the Geolocation object must add the 'geolocation' permission to their manifest. The user's operating system will prompt the user to allow location access the first time it is requested.

Concepts and usage

You will often want to retrieve a user's location information in your web app, for example to plot their location on a map, or display personalized information relevant to their location.

The Geolocation API is accessed via a call to navigator.geolocation; this will cause the user's browser to ask them for permission to access their location data. If they accept, then the browser will use the best available functionality on the device to access this information (for example, GPS).

The developer can now access this location information in a couple of different ways:

• Geolocation.getCurrentPosition(): Retrieves the device's current location.
• Geolocation.watchPosition(): Registers a handler function that will be called automatically each time the position of the device changes, returning the updated location.

In both cases, the method call takes up to three arguments:

• A mandatory success callback: If the location retrieval is successful, the callback executes with a GeolocationPosition object as its only parameter, providing access to the location data.
• An optional error callback: If the location retrieval is unsuccessful, the callback executes with a GeolocationPositionError object as its only parameter, providing access information on what went wrong.
• An optional PositionOptions object, which provides options for retrieval of the position data.

Availability

As WiFi-based locationing is often provided by Google, the vanilla Geolocation API may be unavailable in China. You may use local third-party providers such as Baidu, Autonavi, or Tencent. These services use the user's IP address and/or a local app to provide enhanced positioning.

Microsoft’s HTML5 Add-on To Support H.264 On Chrome & Firefox!

< credit >

If you all remember, Google Chrome will drop support for H.264 in the coming months and will only support WebM (VP8) and Theora codecs.

The reason is being getting into rapid innovation in the web media platform in the coming year and are focusing our investments in those technologies that are developed and licensed based on open web principles.

Well Google has started pushing its browser more towards HTML5 standards. Mozilla’s Firefox and Opera are the other two browsers which are encouraging developers to use WebM codecs.

The only important website that uses WebM is YouTube, Google’s video sharing service. Internet Explorer, Safari and iOS devices are still yet to think about supporting WebM.

Upon all this stories, Microsoft started releasing few add-ons for Chrome and Firefox which keeps them in touch with H.264 video format. Microsoft has started interoperability work related to modern web standards which are no way limited to Internet Explorer 9.

WMP HTML5 Add-on for Firefox

According to Microsoft,

The HTML5 Extension for Windows Media Player Firefox Plug-in is an add-on that enables Firefox users to play H.264-encoded videos on HTML5 pages by using the built-in capabilities found in Windows 7.

The Extension is based on a Firefox Add-on that parses HTML5 pages and replaces Video tags with a call to the Windows Media Player plug-in so that the content can be played in the browser.

This Add-on replaces video tags only if the video formats specified in the tag are among those supported by Windows Media Player. Tags that contain other video formats are not touched.

WMP HTML5 Extension for Chrome

Similar to Firefox add-on, this extension for chrome enables its users to play H.264-encoded videos (aka MP4) on HTML5 pages by using the built-in capabilities found in Windows 7.

Well both the extensions checks if the browsers already supports MP4 (H.264) video codec, if so the extension will not be effective.

It’s very clear that H.264 provides a high-quality videos and is widely-used video format that serves the Web very well today. But browser providers like Google, Mozilla are stopped supporting it as they have to pay more royalties!
