libmpeg2-0.5.1
Introduction to libmpeg2
The libmpeg2 package contains a
library for decoding MPEG-2 and MPEG-1 video streams. The library
is able to decode all MPEG streams that conform to certain
restrictions: “constrained
parameters” for MPEG-1, and “main profile” for MPEG-2. This is useful for
programs and applications needing to decode MPEG-2 and MPEG-1 video
streams.
This package is known to build and work properly using an LFS-7.7
platform.
