Currently, we are not aware of any plans at Apple to update the Apple MPEG Media System to provide video capture of MPEG movies. The MPEG Media System was designed to be a playback-only solution. Future directions of Apple's support for the MPEG standards are being addressed via QuickTime technology.
Since the Apple MPEG Media System is tightly integrated with QuickTime, it is quite feasible to develop MPEG encoding functionality that takes advantage of the hardware included with the MPEG Media System. For more information on how to do this, developers should refer to the QuickTime 2.5 developers guide. This guide can be downloaded from Apple's QuickTime web site at:
