This is a port of x264 0.164.3095_baee400 to MSDOS/DJGPP.


x264 is a free software library and application for encoding video streams
into the H.264/MPEG-4 AVC compression format, and is released under the
terms of the GNU GPL.

Features Overview:
* Provides best-in-class performance, compression, and features.
* Achieves dramatic performance, encoding 4 or more 1080p streams
in realtime on a single consumer-level computer.
* Gives the best quality, having the most advanced psychovisual
optimizations.
* Support features necessary for many different applications,
such as television broadcast, Blu-ray low-latency video
applications, and web video.
* x264 forms the core of many web video services, such as Youtube,
Facebook, Vimeo, and Hulu. It is widely used by television
broadcasters and ISPs.



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

- The source code for this port has been retrieved from www.videolan.org
by cloning the master branch of the git repository like this:
git clone https://code.videolan.org/videolan/x264.git
The version string used internally by this port is generated by version.sh
located in the root directory. It produces the following string:
0.164.3095_baee400
and is useless to produce a meaningfull version number for the DJGPP port,
thus the version number is 1 (one) and will be increased with every new
port release, although I think that there will be no second one.

- A DJGPP specific rule has been added to the configure script, for details
see the patch.

- The reading/writing stream is switched into O_BINARY mode. If the
stream is connected to stdin/stdout/TTY, then Ctrl-C and Ctrl-Break
are re-enabled so the user can interrupt the program.

- The code does not provide documentation in a usefull format, thus
the man page created by the debian port has been added.

- x264 can be tested by compiling and runing the three programs example,
checkasm8, checkasm10.

- There are no user visible changes. Only small changes have been done
to get the library compiled.

- To configure and compile this port at least the following version of
Bash and Make are required:
http://ftp.delorie.com/pub/djgpp/current/v2gnu/bsh4253b.zip
http://ftp.delorie.com/pub/djgpp/current/v2gnu/mak43br2.zip
No previous versions will work nor are supported. Any future version
should work.

- The port has been configured and compiled on WinXP SP3, Win98SE and
MSDOS 6.22 with DOSLFN v0.41f. There is no guarantee that this may
be possible with any other DOS-like OS. Due to the use of long file
names it will not be possible to configure and compile without LFN
support. The port has been compiled using gcc346 and bnu2351b.

As usual, all djgpp specific files (diffs, README files, etc.) are stored
in the "djgpp" directory. The sources have been configured to be build
in the "0build" directory. If for some reason it does not work for you,
delete its contents and configure from scratch again.

Please read the docs to become familiar with this product.


Here is an extract of the CHANGES file showing the user visible changes
from the last port (x264 0.0.0) to this one:
