Those of you starting to use Snow Leopard will notice the new QuickTime player.
Apple markets this as part of QuickTime X. However, it turns out that the new player is a small part of this new version of QuickTime.
As detailed as part of a 23 page technical review of Snow Leopard over at Ars Technica, as with the rest of the OS, most of the changes to QuickTime are hidden from end-users. The first release of QuickTime X is for developers to create new media manipulation applications.
The way Apple does this is through ‘abstraction’ – hiding which software is carrying out requests for applications. For the last few years developers have been asked to use a part of the OS known as QtKit instead of QuickTime 7. In earlier versions of OS X QtKit called QuickTime 7 to perform operations. In OS 10.6 Snow Leopard some operations are carried out by QuickTime X while most are still performed by QuickTime 7. As future versions of OS X are released, more of the application requests will be carried out by QuickTime X.
A wider advantage of Snow Leopard is that more of the OS is 64-bit compatible. The advantages won’t be immediately apparent for most users. This release (and the fact that it doesn’t cost very much to upgrade) is to encourage developers to create 64-bit applications and drivers. The eventual benefits will be access to virtually unlimited amounts of memory and much better processor performance.
