MPEG 1 Playback

QuickTime 5 includes support for the following:

• MPEG 1 playback, both local and streaming on Macintosh and Windows computers.
• Layer 1 and 2 audio support.
• Support for RTP packing for streaming (RFC 2250).
• Support for elementary and muxed streams.
• Enabling of frame-accurate access and effects compositing.

It is not currently possible to export the audio portion of a muxed MPEG1 audio/video stream using QuickTime. Also, for editing purposes, the entire MPEG1 stream is treated as a single sample--you may create edit lists to display parts of the stream in the usual way, but if you flatten the movie data, the entire stream is saved, not just the parts displayed in the movie.
