StageVideo – A new way to render video

Tween issues in loading AVMovie1 in AVMovie2

leave a comment »

Today I was working on an ActionScript project while I came across an interesting fact which I would like to share.

I had a Tween created in my home.swf which works well on first load within AVMovie2. But the problem started when I navigated to another section and again returned to Home.

Adobe CS5 roadshow @ Oberio Grand, Kolkata on 16th June, 2010

with one comment

Hello Guys, today I attended the Adobe CS5 roadshow event at Oberio Grand, Kolkata.
Some cool awesome features of CS5 suite got displayed by Rajesh Patil, Vyshak V and GuruVaidya.
After the event I really felt – being a pure ActionScript developer, its a must to have version; and adding to its beauty of quick coding comes with Adobe Catalyst.
I will try to list some features in another post, may be in some times. Meanwhile look here for more.

Anyways , thanks the three for the wonderful eventful session. Cheers 🙂
