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-7.6 systemd platform.

User Notes:

Installation of libmpeg2

Install libmpeg2 by running the following commands:

sed -i 's/static const/static/' libmpeg2/idct_mmx.c &&
./configure --prefix=/usr --disable-static          &&

To test the results, issue: make check. To perform a more comprehensive regression test, see the file test/README in the source tree.

Now, as the root user:

make install &&
install -v -m755 -d /usr/share/doc/mpeg2dec-0.5.1 &&
install -v -m644 README doc/libmpeg2.txt \

Command Explanations

sed -i ...: This sed fixes problems with recent GCC compilers.

--disable-static: This switch prevents installation of static versions of the libraries.
