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.
本パッケージは LFS-10.0 において正しくビルドでき動作することが確認されています。
