From James Ward – RIA Cowboy here is the first view of Flex 4 running on mobile platform. As he reviews Flex 4 performance, with flash player 10.1 is the first light of hope for the rest of us.Read his article here.For a quick view have a look at the videos he posted.
Here is a little demonstration of the new spark video player in Flex 4 SDK, that plays a rtmp stream from Red5. The Flex 4 SDK is still in beta as of this date and thus there may be some issues if you use it commercially right now. I had some issues with autoplay being false. So i have tried with [autoPlay = true] instead. However i must say it works much better than Flex3 VideoDisplay component with Red5.
