After Microsoft already half a year ago www.slashcam.de/news/single/Microsoft-Silverlight-3-wird-H-264- HD Flash Video - 7118.html (announced) is that Silverlight (Microsoft's answer to Adobe Flash) H.264 and AAC audio support, is now actually the first / Developer) beta version of Silverlight appeared, the H .264 play. This means that in future MPEG-4/H.264 encoded videos are not new to Microsoft's VC-1 must be transcoded to also play in Silverlight - a concession that Microsoft probably had to make in order to compete with Flash fight to preserve opportunities - without but too much of Windows Media abandon. It supports videos in. mp4 (. f4v and. m4a) and. mov format in the H.264 profiles Simple, Main or High 4:2:0
encoded (only progressive scan) and AAC-LC audio, but not HE AAC, which is only in lower quality (like in QuickTime) is playing. Thus Silverlight videos play all MPEG-4 video, which also run Flash or QuickTime. Also supports this beta version of the first operations using the graphics card / GPU (on Windows, like OS X), namely scaling and compositing - what is reflected in a lower CPU load, ergo lower system requirements particularly in complex operations such as the scaled integer screen video playback is much lower CPU load is clearly perceived to be. Also interesting is the new nerddawg.blogspot.com/2009/ 03/introducing-offline-and-out-of-browser.html (Out-of-browser) or offline functionality Silverlight: Silverlight Applications can be designed such that they are also outside of the browser running on the desktop when the user Drag & Drop from browser to the desktop should be considered. They then behave like normal programs, is from the desktop or the Start menu and can be linked via double click to start - but do not require Administrator rights, because they are in a secure sandbox isolated from the rest of the system running. The program also remembers whether it is in the network or not and behave accordingly: outgoing data can be cached until connection to the network, and the application can then be automatically updated. Advantage: cross-system (Windows / Mac) applications, even without a network and browser to run - what the browser like it, can simply be installed locally. This feature could be a great advantage over flash, if the relevant applications and a greater Userbase set.
