You don't own a Mac, do you? From what I hear the Flash Player on Mac slower and more crash-prone than on Windows - which is ironic given that designers, Adobe's core audience, are more likely to use a Mac than your average user. Adobe's CTO said as much about it being slower (http://news.cnet.com/8301-30685_3-20000055-264.html). OS X has a application crash report features, and Apple claims that Flash accounts for quite a lot of the crashes. Very few mobile devices had the full Flash Player - one that has is the Nokia N900, and a test labeled Flash video in a web browser a slideshow. The key for mobile video is hardware accelerated video decoding which Flash Player 10.1 will bring for some mobile graphics hardware (launch planned for H1/2010). The iPhone and other platforms already support H.264 in hardware, so that would be a good guess for the video format. The Flash evangelist showed rendering vector graphics in pre-release of Flash Player 10.1 vs HTML 5 canvas. I guess that Flash Player uses hardware acceleration where the browser does not, hence the huge difference. The benchmark situation doesn't strike me as a particular typical use of Flash vector graphics (raise your hand if the Flash ads / grapics you see are bouncing balls), but it shows that the Flash Player can be on the same performance level as native programs when fully using the hardware. Since the benchmark doesn't run much calculations, the potential disadvantage of Actionscript vs native code doesn't come into play. -- You received this message because you are subscribed to the Google Groups "The Java Posse" group.
