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.



Development versions of BLFS may not build or run some packages properly if dependencies have been updated since the most recent stable versions of the book.

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    \
            --enable-shared  \
            --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/libmpeg2-0.5.1 &&
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.
