I am having an issue with quicktime, it wont play AVI's even with Perian installed on mountian lion. anyone else having this issue? any solution? perian is updated too. thanks
MPlayerX which is a free download from the app store plays avi files and it has a quicktime look.
VideoToolbox is a pretty old framework. VideoToolbox was a private framework on previous versions of OS X.There's a new framework in ML called "videotoolbox" that deals with video decompression.
