libmpeg2-0.4.0b

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.

Installation of libmpeg2

Install libmpeg2 by running the following commands:

./configure --prefix=/usr --enable-shared &&
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-0.4.0b &&
install -v -m644 README doc/libmpeg2.txt \
    /usr/share/doc/mpeg2dec-0.4.0b &&
install -v -m755 doc/sample? /usr/share/doc/mpeg2dec-0.4.0b

Command Explanations

--enable-shared: This parameter forces building shared versions of the libraries as well as the static versions.
