At IBC2008, Adobe is also previewing new technologies that will be available in future versions of Adobe Flash Media Server. These include dynamic streaming for delivering the highest quality, uninterrupted viewing experience, and the ability to pause or rewind a live video stream. Expect more news from IBC over the coming days.

Full press release here.

So what have we got here? My PureMVC Skeleton App is a simple Flex project that uses thePureMVC framework to give you a bit of a head start with your next FMS project. I'm by no means suggesting that this is the best way to build an FMS app but what I can say is that it works well for me. Not only that but since I've picked up PureMVC I have been able to build much larger projects than ever before, and the framework allows me to come back to an app months later and pick it up in no time at all. Everything has its place and it's easy to find your way around, and projects generally end up well maintained.
One thing I should point out is that the app itself has no UI - there's nothing to see when you compile it (hence the skeleton bit in its name). You will however see traces if you compile a debug project, or install Firebug for Firefox so you can see the Thunderbolt AS3 traces I tend to use extensively.

In order to connect to your own FMS application you first need to create it on FMS (mine is called pmvcskeleton) and then go into the ResourceBundleProxy and on line 42 add your corresponding RTMP string. I'm not sure if this is a good idea but I often use ResourceBundles for configuration options such as the RTMP string, I find it quite handy since they usually do not change so I just compile that in.

It helps if you are a bit familiar with FMS based applications and the MVC design pattern. For everything else check out the PureMVC website, it has tons of info and a lively community. Or why not sign up to my FlashMedia List, there's always a bunch of knowledgeable people there ready to help.

On this note I will leave you to it, take a look at the app and feel free to post a comment if anything isn't clear.

Massive thanks to Simon who gave me some excellent tips when I got stuck with certainPureMVC nags.

This release mainly adds new features such as the new Dynamic Streaming, DVR functionality, HTTP delivery support, and H.264 enhancements. There are no changes in licensing or pricing. The editions also remains unchanged with the Flash Media Streaming Server (FMSS) taking care of your live and on-demand streaming needs while the Flash Media Interactive Server (FMIS) provides more complex features such as recording capabilities and Origin-Edge setups, as well as full support for server side scripting.
Of course you can also try the free Flash Media Development Server 3.5 and use all the features of FMIS up to a limit of 10 connections.

Flash Media Live Encoder, Adobe's free live encoding tool for broadcasting live streams has also seen an update today, bringing it up to version 3.0. The major new feature here is the ability to encode multiple streams in multiple bitrates at once, publish them to FMS 3.5 and then make use of the Dynamic Streaming feature in a live setting. Pretty cool stuff.

You can download Flash Media Live Encoder 3.0 from this page.

According to Adobe's Serge Jespers, the RTMP details will soon be published on Adobe.com. The full press release is here.

"With the RTMP specification, developers and companies will be able to provide users with optimized audio, video and data streaming, no matter what kind of device the user is on or where the content is coming from," said Adobe CTO Kevin Lynch. "Our ongoing commitment to openness is accelerating adoption of the Flash Platform by developers and resulting in a new generation of Web applications, content and video experiences that run reliably across operating systems and devices."

Understandably Adobe will not release details of the secure variants of RTMP such as RTMPE since it forms the backbone of some of the content protection measures in Flash Media Server.

Strobe is trying to alleviate these pains by providing a player framework which can be extended through a plug-in model. For example the connection routine between CDN A and CDN B differs drastically. In this case Strobe should (once released) allow both CDNs to provide connection routine plug-ins for Strobe (these may simply be some ActionScript3 classes) which developers can leverage easily without having to rework their existing video player code - provided it is built on top of Strobe.

Connection routines are of course just one aspect. Other implementation points may include advertising insertion, content syndication, micropayments, viewer authentication, transaction handling, and business model controls.

According to the FAQ Adobe Strobe is planned for release around the third quarter of 2009.

We also released the new DVRCast application that makes it easy to add DVR-enabled live streams to your website using Flash Media Server 3.5.

There's much more info on the new features on Kevin's blog.

I can't wait to try these new features - just need to wait for the next suitable live event :-)
I think it is highly likely that this is the last update to the FLVPlayback component we will see as the upcoming Strobe framework is likely to replace the efforts made my the component. Love it or hate it, the FLVPlayback component helped countless Flash newcomers to get their video content online quickly. If this is indeed the last update then it will go out with a bang as these new features are pretty cool - and we've got a Flex version thrown in too.
