ANNOUNCE: DJGPP port of libmpeg2 and mpeg2dec 0.5.1 uploaded

Post by Juan Manue » Fri, 20 Feb 2009 05:47:05

This is a port of libmpeg2 and libmpeg2 0.5.1 to MSDOS/DJGPP.


libmpeg2 is a free library for decoding mpeg-2 and mpeg-1 video
streams. It is released under the terms of the GPL license.
mpeg2dec is a test program for libmpeg2. It decodes mpeg-1 and mpeg-2
video streams, and also includes a demultiplexer for mpeg-1 and mpeg-2
program streams. It is purposely kept simple : it does not include
features like reading files from a DVD, CSS, fullscreen output,
navigation, etc... The main purpose of mpeg2dec is to have a simple
test bed for libmpeg2.

DJGPP specific changes.
=======================

- The DJGPP specific changes to the sources are those required to pacify the
compiler and to include the right headers to provide the required functions
prototypes. To avoid a 8.3 file name collision between libmpeg2.[a|la] and
libmpeg2convert.[a|la] the later has been renamed to libmpg2convert.[a|la].
As for all binaries and libraries that handle images of any kind, it should
be noticed that files (streams) are *always* openend in binary mode with
all the well known implications on a DOS/WINDOWS OS if the stream is
connected to STDIN and/or STDOUT when these are still connected to the
console.

- To configure and compile the sources you will need LFN support. This means
that you can only unzip and build the binaries on an OS that offers LFN
support like Win9X, WinXP, etc. There will be no support for the building
on plain DOS by me. IMHO this is not worth to be done nowadays if the
amount of work exceeds certain limit. It should also be noticed that you
will need the bash port bsh205bbr2.zip to compile the sources; bsh204br2.zip
does not work, it is not able to process certain parts of the libtool script
and I have not investigated this issue further. I also do not if the ports
bsh205bb.zip and bsh204b.zip work or not.
Of course, the distributed and/or build binaries and libraries will always
work on plain DOS.
As usual, all DJGPP specific stuff is located in /djgpp dir.


Please *read* the docs stored in /contrib/libmpeg2.051/doc to become familiar
with this product.
