For my dear, wonderful parents, Haluk and Mehlika Balkan. Thank
you for a lifetime of unconditional love and support. Thank you
for believing in me. Thank you for teaching me that I can do
anything I set my mind to. I am forever in your debt.
—Aral Balkan
To Airi.
—Nicolas Cannasse
A glass raised to Winsor McCay—the original animator and one of
America’s greatest talents.
—Moses Gunesch
To my wife, Jess, for putting up with me, and to the open source

community, for constantly amazing me.
—Marc Hughes
To my family and friends who provide constant encouragement
and support even though I often take on much more work
than our relationships should allow.
—R. Jon MacDonald

and security conferences. He has an active dialogue with Adobe and
actively participates in prerelease beta development of Flash, Flex,
and AIR, and he is passionately involved in open source Flash/Flex
development and aligns T8DESIGN behind these initiatives. Wade is
the lead developer of AMFPHP and the open source implementation
of Flash Remoting. Wade has a degree in computer science emphasizing intelligent systems and
an MBA from the University of Iowa. T8DESIGN works with hundreds of community banks
and medium to enterprise customers including Nike, McDonald’s, John Deere, AT&T, Lindsay

ABOUT THE AUTHORS

Aral is a published author and has contributed to several books and magazine articles.
Specifically, he is the author of the Adobe Flex 2 QuickStart Guide and Flex 3 QuickStart Guide
and has authored six courses on Flash, Flex, ActionScript, and open source development.
Aral is a regular speaker at international conferences including Macworld, FlashForward,
d.construct, FITC, Wizards of OS, and Adobe MAX.
Nicolas Cannasse is one of the cofounders of OSFlash.org and the
creator of the MTASC compiler. He is also the CTO at Motion-Twin, a
French independent game studio making web games in Flash. For
the past two years, he has been working on haXe, an open source
programming language for the Web, capable of compiling to Flash
but also to JavaScript and the server side.

With more than eight years of experience in working with Flash
technology, John Grden is the creator of the Xray debugger, FLEXible
(an MXML editor), and the FLASC compiler GUI, and he is a core
member and contributor on the Papervision3D project. John also

Moses Gunesch has spent a decade teaching and working with
ActionScript, inspired early on by Flash phenomena like Flight404.com,
Remedi Project, Praystation, Second Story, Deconcept, Natzke.com,
Yugop.com, and Robert Penner. MosesSupposes.com is currently
based in Brooklyn, where Moses can be found architecting largescale web applications for advertising clients and startup ventures
(between tasty slices of New York pizza). His current interest in
social networking design is rooted in having cofounded the popular
GotoAndPlay.net group in his hometown of Portland, Oregon, in
2001—a hub for Flash, 3D, and graphic design professionals and
host to its own digital film festival. Moses established himself as a leading figure in animation
systems for ActionScript with his popular Fuse Kit. Fuse has now been used in more than 60
countries, as well as in many top advertising agencies and award-winning websites. Moses strives
to continue contributing valuable ideas to the ActionScript community via open source.

ACKNOWLEDGMENTS
I would like to thank my wife and business partner, Rebecca Allen, for supporting me while I’m
trying to do too much. I would also like to thank everyone on the Red5 team for doing their
parts to make Red5 a reality. Some of those guys include John Grden, Luke Hubbard, Joachim
Bauch, Dominick Accattato, Paul Gregoire, Steven Gong, and Thijs Triemstra. It’s also worth
mentioning a word of gratitude to conference organizers Shawn Pucknell, Stewart McBride, and
John Davey for seeing the potential and interest in Red5 and being willing to take a chance on
letting us present on our technology before it was the thing to do. Others who deserve mention
are Keith Peters, Sam Agesilas, Todd Anderson, Jon Valliere, Andy Zupko, Richard Blakely, Jerry
Chabolla, and Paul Blakely. Then of course there’s the whole team at friends of ED that made
this book possible: Chris Mills, Ben Renow-Clarke, Pete Aylward, Kylie Johnston, Kim Wimpsett,
and the rest. Thanks!
Chris Allen
I would like to thank the community of developers who continue to push what is capable
online. Your questions and inspirational projects are what keep me working into the late hours
to push what is possible. To Dr. Gray and Dr. Wallingford, thank you for teaching me how to
think computer science. For allowing me to start working on computers from an early age when
the rest of the world could not even access a PC, thank you, Mom and Dad; in addition to
resources, thanks for aiding in the development of my perseverance. And most important,
thanks to my amazing wife, Shannon, who not only puts up with but supports my dreams.
Bushel and a peck, Shannon, David, and #2!

I want to thank the open source Flash community: every day I learn from you, I get inspired by
the amazing things you do, and I feel honored to count so many of you among my friends. You
make a difference every day by sharing your knowledge and your passion with others. You are
the soul of Flash.
Aral Balkan
I’d like to thank Aral for being a good friend and allowing me to help out way back when we
were creating new OS projects by hand and for giving us a place to park these awesome ideas!
Without Aral, we wouldn’t have a community like we do now—that’s a fact. Also, I don’t know
where I’d be without Chris Allen—he has been a great friend, has been an awesome mentor,
and has really made an impact on my Flash life. I couldn’t have gotten this far without him. I
have to say thanks to Luke Hubbard, Joachim Bauch, Steven Gong, and Dominick Accattato for
having the backbones to jump in on Red5 from day one and make it happen! That comprises
the “original 6” that was known back in the day when Red5 first breathed life. I have to give

ACKNOWLEDGMENTS

thanks for my family as well: Linda, Riley, and Luke (yes, I named my son after Luke Skywalker—
get used to it). Because of them, I was able to do these projects and succeed, and they’re the
coolest fans I could ever ask for. I love them dearly. And mostly, I want to thank God for all the
blessings he’s given me; by saving me from either myself or calamity altogether, he’s always
been by my side, and I’m most grateful for His patience, peace, and help in my life. Rock on.

I would like to thank my parents, whose foresight to put a Commodore 64/128 in my bedroom
as a child provided me with the start to a wonderful means of turning a passion into a living.
Thanks to Aral Balkan for providing me with this opportunity and trusting me to do right by his
project. Thanks to all of my co-workers, past and present, who have influenced and aided in my
growth as a developer. Finally, thanks to the amazing Flash Platform community—without such
an active and open community, projects like those included in this book would not exist.
