First, from what I can tell, the ARM emulation isn't that efficient. I mean, it's not horrible, but it's not exactly like Intel code. Second, there is no hardware graphics acceleration (despite the qualifications of the host PC), so there's that much more work that the CPU has to do. Beyond that, I'm just speaking from personal experience. I have a dual-core 2.5GHz Dell Vostro notebook with a pretty good discrete graphics card, and it cannot play back videos. Before that, I had a Pentium M 2.0 HP notebook with a pretty good discrete graphics card, and it could not play back videos. I have a quad-core 2.66GHz desktop with a pretty good discrete graphics card, and it can *usually* play back videos. I have taught a number of courses and, based on student results, you gotta have pretty serious horsepower to play back video. Anyone serious about video playback needs hardware for testing, IMHO. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://github.com/commonsguy http://commonsware.com/blog | http://twitter.com/commonsguy _Android Programming Tutorials_ Version 2.9 Available! -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
