MPEG-1 Media

MPEG-1 media is used to store MPEG-1 video streams, MPEG-1, layer 2 audio streams, and multiplexed MPEG-1 audio and video streams in QuickTime movies. It has a media type of 'MPEG'.

In this section:

MPEG-1 Sample Description
MPEG-1 Sample Data


MPEG-1 Sample Description

The MPEG-1 sample description uses the standard sample description header, as described in “Sample Description Atoms.”

The data format field in the sample description is always set to 'MPEG'. The MPEG-1 media handler adds no additional fields to the sample description.

Note: This data format is not used for MPEG-1, layer 3 audio, however (see “MPEG-1 Layer 3 (MP3) Codecs”).

MPEG-1 Sample Data

Each sample in an MPEG-1 media is an entire MPEG-1 stream. This means that a single MPEG-1 sample may be several hundred megabytes in size. The MPEG-1 encoding used by QuickTime corresponds to the ISO standard, as described in ISO document CD 11172.
