29 | The <application>libmpeg2</application> package contains a library for
|
---|
30 | decoding MPEG-2 and MPEG-1 video streams. The library is able to decode
|
---|
31 | all MPEG streams that conform to certain restrictions: <quote>constrained
|
---|
32 | parameters</quote> for MPEG-1, and <quote>main profile</quote> for MPEG-2.
|
---|
33 | This is useful for programs and applications needing to decode MPEG-2 and
|
---|
34 | MPEG-1 video streams.
