HTTP Dynamic Streaming – Part 2: Late-Binding Audio Using OSMF

Part 1 of this series discussed HTTP Dynamic Streaming (HDS) at a fairly high level. The next few editions in the series will explore some of the more powerful features that make using this protocol advantageous. Multi-bitrate stream switching and file encryption are two important features that we’ll cover in the very near future, as they’re very big reasons to stream over any protocol. However, in this article I’d like to discuss a brand new feature of the Open Source Media Framework (OSMF) known as “late-binding audio”.

HTTP Dinamic Streaming – Deo 1: Uvod u striming medije (Yugoslavia)

Kao tehnologija koje se odnosi na proizvodnju i isporuku digitalnih pokreta medija nastavlja da napreduje, tako da su zahtevi potrošača za sve raznovrsniji i bogatiji mediji iskustveniji.. Video visoke definicije se sada isporučuje na više korisnika, na razlicitim vrstama uređaja, i kroz više kompleksnih mreža nego ikada pre. Za provajdere sadržaja, to naravno znači više raspoloživih mogućnosti za medijsku distribuciju i monetizaciju.

HTTP Dynamic Streaming – Part 1: An Introduction to Streaming Media

As technologies related to the production and delivery of digital motion media continue to advance, so do consumer demands for an increasingly varied and rich media viewing experience. High-definition video is now being delivered to more users, on a wider variety of devices, and through more complex networks than ever before. For content providers, this of course means more available avenues for media distribution and monetization.

Mobile Flex: View Data

From the previous post you should know how to navigate from 1 view to the next using the ViewNavigator.  Now, you want some data in that view right? No problem, this is where the View object’s ‘data‘ property comes into play. Setting the data property is accomplished by passing the data object, in addition to the View’s class name, into the pushView() method on the navigator object.

Example:

navigator.pushView(MyNewView, dataObject);

This effectively calls the setting for the data property of the new View (MyNewView) object that is created.

Managing View Data

You could work with the data property on the View object directly. For instance, if the data object passed into the View via the pushView() method was a simple user object that contained a name property, you could bind the name property to a label control.

Example:

<s:Label id="name_lbl" text="{data.name}" />

Overriding the Data Property Setter

Usually though, you’d want to override the setter for the data property. Then you can type your object and work with it in a better manner.

Example:

protected var user:User;
override public function set data(value:Object):void
{
 super.data = value;
 user = value as User;
}

 

<s:Label text="{user.name}" />

So now we’ve got the data in the view. The next step is to manage the state of each view. With mobile apps you can’t count on the view staying around, so we’ll need to keep a tight control on the state of each view. That way we can bring the user right back where they expect to be when they come back to the app after a call for example. In the next post we’ll look into how to do this. Stay tuned.

Mobile Flex: ViewNavigator Basics

Flex 4.5 provides some pretty slick updates and enhancements, the least of are the of Mobile components and the ability to easily slam out some pretty nice mobile apps. The first thing I’d like to talk about is a new concept, the ViewNavigator. The ViewNavigator provides some pretty intense functionality such as view management.
