Flash Media Playback is a brand new free media player for Flash that makes it much easier to deliver high quality video the widest possible audience using Adobe Flash Player. Flash Media Playback has been designed to make it super simple to deploy video in no time at all with full support for all the delivery technologies including RTMP/RTMPe HTTP Dynamic Streaming and Progressive Download. All you need to do to use it is add some simple HTML to your webpages – The actual SWF file will come from Adobe.

Flash Media Playback is built on top of the Open Source Media Framework and as part of that framework has full support for all of the third party plugin services from key service providers supporting the framework. Service providers such as CMS, CDNS, Advertising and Analytics that help you drive a business delivering video on the web.

Using the Flash Media Playback video player

To incorporate the Flash Media Playback video player into your web page, simply add the player embed code to the HTML page. When visitors load the web page in a browser, FMP is automatically displayed with your video playing on the page.

Flash Media Playback Setup page

To copy the embed code, visit the Flash Media Playback Setup page at The Flash Media Playback Setup page (see Figure 1) contains two main sections on the left and the right. Use the form on the left to enter the values for your video: video source location and various custom settings. The right side of the page contains a preview player and the preview embed code.

Model Driven Development with Adobe Flex

Posted: August 30, 2010 in LCDS
Tags: ,

Adobe has developed a new technology, code named Fiber, which brings model-driven development to Flex developers. With Fiber, developers start by creating an application model from which they go on to develop the Flex user interface and the server business logic. It is easier and quicker to now develop Flex applications with Flash Builder 4 and LiveCycle Data Services 3.
The beta version of LiveCycle Data Services 3 provides a Fiber model run-time, and thus enables data persistence out of the box. With Fiber, data management is implicitly supported and does not require developers to create custom assemblers or employ complicated LiveCycle Data Services specific configurations. More often you can develop a functional application skeleton or prototype without ever having to write any Java or Flex code.

The new modelling features offer developers a complete front-to-back solution, including the necessary tools for building production applications. The key tool is the LCDS plug-in for the Flash Builder 4 IDE, recently released into beta, which includes a built-in modeller and strong service integration for developing the client side Flex application. There are other new features in the release, including support for reliable communication and data throttling. To learn more about the release check out this article. Also, Adobe has published a couple of videos on the new features (one & two).

Youtube gets an HTML5 website for mobiles

MOBILE HTML5 VIDEO is now accessible at Youtube through a website dedicated to the format for smartphones, tablets and other mobile devices.

Youtube’s owner Google said that with mobile web browsing expected to overtake desktop browsing it has updated its mobile video website for use on-the-go. With the update Google has added features from the main Youtube website such as like/dislike ratings, the ability to share links with social notworking services such as Facebook, Twitter and Buzz, plus the ability to load videos in lower quality more quickly.

“People want access to videos at all time[s], and they want to do so as quickly and consistently as possible,” said Youtube’s product manager for mobile, Andrey Doronichev. “With this new site, users can get the same experience on their smartphones or tablet devices in terms of both speed and functionality as they do on the desktop as we have streamlined the site to work over 3G networks as fast as possible.”

The Youtube HTML5 website has been designed to offer a consistent user experience on all mobile devices, including the Ipod Touch and the Ipad. Samsung’s Bada OS, as used on that firm’s Wave smartphone, is currently not supported by the website but Google explained that it will be after the first maintenance release of Samsung’s browser.

Youtube’s mobile website now also comes with large, touch-friendly buttons that make navigation easier by removing the need to scroll or zoom. Doronichev also took a swipe at mobile manufacturers by arguing that because the website is managed by Google directly, updates will be done far more regularly than those from phone manufacturers who only periodically update their native applications.

Accessing the USB port

The Arduino is an inexpensive, easy to find, open-source hardware prototyping platform.  You can connect a wide variety of sensors and other electronics to it, and then using the open-source as3glue “Physical Interaction Library for Flash” you can communicate via the USB port with Flash or AIR.


  1. Get an Arduino, a basic one goes for about US$30.  Download the driver and software for your OS from the “Download” section of the Arduino web site and install them.
  2. Download the as3glue files from the Google Code website.  It will include the installs for Standard Firmata and Serproxy that you need for later steps.  (Note: The Serproxy included is for Windows and Mac only.)
  3. Plug your Arduino into the USB port and upload the Standard Firmata.  This sets up the Arduino to use a standardized protocol for communicating with a host computer.
  4. Unplug your Arduino and connect up your sensor, probably to one of the analog input pins.
  5. Install Serproxy on your computer.  (Or another serial port proxy if you are not using Windows or Mac.  Sorry but I can’t help you with that.)  Serproxy will take the USB input from the Arduino and act as a serial server which your Flash or AIR app will open a Socket connection to.
  6. Plug the Arduino into your USB port, start Serproxy and you’re ready to use as3glue to receive the sensor’s output in Flash or AIR.  There are some example .fla files included in the as3glue download that show how to code this.
  7. Celebrate! 🙂
PS:  If you have a problem with loading the Standard Firmata that comes with as3glue onto your Arduino you may want to try a newer version, which you can download from the Firmata Wiki here

For communicate with device (in my case a biometric scanner) via RS232. This involves interpreting the serial output from the device and sending the device commands as required.

Use the freeware application ‘Serproxy’ to redirect serial communication with the device via a network socket connection to my Air application.

Serproxy can be found here:

Serproxy is a multi-threaded proxy program for redirecting network socket connections to/from serial links, in cases where the remote end of the serial link doesn’t have a TCP/IP stack (eg an embedded or microcontroller system). The proxy allows other hosts on the network to communicate with the system on the remote end of the serial link. The Linux version requires a recent version of libpthread to compile/run.’

Follow the readme to configure the program, its very simple and in my month or so of use has been rock solid.

Note: I found that I had to configure ‘newlines_to_nils=false’ (not true as suggested in the config comments) to get consistant text from the serial port.

Now for the socket connection in you Air application:

I created a singleton class called BiometricScanner. I will leave you to look up singetons in as3 elsewhere should you require them as there are more complete solutions than the one I implemented.

The basics of the socket connection to Serproxy are simple – initialise the connection (if serproxy is running on your local machine: localhost, 5331), then parse and handle incoming data and send outgoing commands as required.

private var _socket:Socket;

         * Constructor
        public function BiometricScanner(caller:Function = null)
            // init socket connection for serial to tcp/ip bridge
            _socket = new Socket();
            _socket.addEventListener(Event.CONNECT, onConnect);
            _socket.addEventListener(ProgressEvent.SOCKET_DATA, onSocketData);
            _socket.addEventListener(IOErrorEvent.IO_ERROR, onIOError);

         * connect to the biometric scanner socket.
        public function connect(scannerSocketIPAddr:String, scannerSocketPort:Number):void
            _socket.connect(scannerSocketIPAddr, scannerSocketPort);

         * disconnect from the scanner.
        public function disconnect():void

         * handles scanner connect successfult event.
        private function onConnect(event:Event):void
            // dispatchEvent(…)

         * on IO Error
        private function onIOError(event:IOErrorEvent):void
            // dispatchEvent(…)      

         * called when data received from the socket connection
         * AKA the serial connection
        private function onSocketData(event:ProgressEvent):void
                var temp:String = _socket.readMultiByte(_socket.bytesAvailable, "ISO-8859-1");

                // process buffer, throw an event, whatever you want
                // processBuffer(temp);
                // TODO: throw exception or event

         * send text command to scanner.
        public function sendSerialCommand(cmd:String):void

Finally we need to included Serproxy and its config as an asset to be deployed with my air application. Now we need to addedd Serproxy to windows startup although you could launch it from you app as needed if using Air 2.

Alternatively you could use merapi and write a serial reader/writer in java.

Adobe’s Flash technology has been taking a beating lately. Apple (AAPL) still won’t support it on its upcoming iPad or its iPhone. Steve Jobs calls it buggy and crash-prone and dismisses Adobe (ADBE) as being lazy. Adobe is trying to fight the negative vibes emanating from Cupertino and elsewhere. It has already pointed out that it will be easy to convert Flash apps into iPad apps, and now CTO Kevin Lynch is weighing in to defend Flash.

In a blog post Tuesday, Lynch addresses the two major threats to Flash: Apple’s refusal to support it on mobile touchscreen devices and the rise of HTML5 as a new, open standard which may one day replace Flash. On Apple, Lynch says Adobe is ready and able to put Flash on the iPhone, the iPad or anything else Apple can throw its way. But, as has been the case for more than a year, the ball is in Apple’s court:

We are ready to enable Flash in the browser on these devices if and when Apple chooses to allow that for its users, but to date we have not had the required cooperation from Apple to make this happen.

Lynch points out that the next version of Flash for smartphones, 10.1, is about to become available and that practically all other smartphones will support it, including Android, Blackberry, Nokia, and Palm Pre. If they can handle it, why can’t an iPhone?

But the bigger long-term threat to Flash is HTML5, especially for rendering video. Lynch says that 75 percent of video on the Web currently is shown in a Flash player. That number could decline if HTML5 video starts to take off. Google (GOOG) (via YouTube, Chrome, and other products) and others are pushing HTML5 hard. Lynch tries to pretend that HTML5 is not a threat, saying in the same breath that Adobe supports HTML5, but its incompatibilities across browsers spells doom for the Web. He writes:

Adobe supports HTML and its evolution and we look forward to adding more capabilities to our software around HTML as it evolves. If HTML could reliably do everything Flash does that would certainly save us a lot of effort, but that does not appear to be coming to pass. Even in the case of video, where Flash is enabling over 75% of video on the Web today, the coming HTML video implementations cannot agree on a common format across browsers, so users and content creators would be thrown back to the dark ages of video on the Web with incompatibility issues.

HTML5 is still a young technology, and those incompatibility issues can be solved over time. Flash is still a more capable technology when it comes to rendering video, but HTML5 is advancing faster and as a native Web standard it has many other advantages which may help it win over time.

Adobe is in a battle for developers, who buy its Creative Suite software to make Flash apps. As long as Flash is the de facto standard for video and animation on the Web, those sales will not be threatened. But if Flash developers migrate to other technologies to build better apps for the Web and mobile devices such as the iPhone and iPad, Adobe’s competitive position will be weakened. It will defend Flash to the death.
