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-7.6
systemd platform.

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 &&
make
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 \
/usr/share/doc/mpeg2dec-0.5.1
Command Explanations
sed -i ...: This
sed fixes problems
with recent GCC compilers.
--disable-static: This
switch prevents installation of static versions of the libraries.
