Introduction
------------
The DivX(tm) codec v4.0 is the latest and greatest release of DivX,
the best compression technology for high-resolution movies. The DivX
codec (short for COmpression-DECompression) is becoming the standard
for high quality video over IP networks because it hits the sweet spot
between superior visual quality and small file size. With a broadband
connection, you can download a full-length feature film in the time it
takes to have a pizza delivered!
THIS INSTALLER WILL _NOT_ INSTALL THE PLAYA. IF YOU WANT THE PLAYA,
YOU SHOULD VISIT DIVX.COM AND DOWNLOAD THE FULL DIVX 4.0 INSTALLER.
Installation instructions
-------------------------
To install the DivX codec, you should follow the following simple steps:
1. Copy the installer program (DivX4CodecInstaller.exe) to a location on
your hard drive (e.g., C:\temp).
2. Run the installer program by double-clicking on the
deainstaller.exe icon.
3. Follow the instructions of the installer program to install the
DivX Codec.
4. Done! The CODEC should be installed in your Systems directory.
**What files are installed?**: The DivX Codec installer will install the
following files on your system:
* divx.dll (DivX Codec)
* divxdec.ax (DivX Decoder Filter)
* Help.chm (DivX Help File)
* README.txt (This README file.)
* License.txt (License agreement for the CODEC.)
**Uninstalling the DivX Codec**: To remove the DivX Codec from your
system, you should use the "Add/Remove Programs" control panel in
Windows. To this by selecting "Start -> Settings -> Control Panel ->
Add/Remove Programs" from the Windows Start menu. In the listbox that
is presented to you, choose "DivX 4.0 Beta Codec" and click "remove."

What's new in the DivX(tm) codec
--------------------------------
**Features of DivX 4.0:**
* Improved decoder performance
* Higher encoding performance, almost 4 times faster than
previous versions
* Multi-pass encoding and 2 different variable bit rate modes
* Improved visual quality
* Highly scalable codec from 16x16 to 1920x1280 (i.e. HDTV). All even
integer dimensions are acceptable
* Support for popular encoding/editing applications
* Plays all DivX content
** Bugs Fixed in the DivX 4.0 (Beta 3) release:**
* DivX decoder registered itself for 3.x formats even if user answered
"No" when installing
* Found one more bug in 3.x decoder
* Fixed problem with quality loss when encoding at height
not multiple of 16 and low resolution
* Fixed crash when encoding on Pentium II / Celeron machines
(accidentally introduced in beta 2)
* Fixed noise problems in playing 3.x content
* More accurate 2-pass VBR
* Rearranged controls in encoder config dialog
** Bugs fixed in the DivX 4.0 (Beta 2) release:**
* DivX DirectShow filter did not work on Windows NT 4.0
* Encoding was broken at very high bitrates. You would receive scrambled
picture if you tried to encode either in quality-based VBR at quality
level >=95% or in two-pass VBR at bitrates roughly higher than
1500-2000 Kbps
* Decoder was crashing in some cases on Pentium II and Celeron machines
(a few SSE instructions were accidentally put into MMX YUV->RGB
conversion routines)
* Decoder was crashing with post-processing level 6 or 7 and 16*N <
height <= 16*N+8
* Fixed on obscure DivX 3.x decoder incompatibility issue
* DivX decoder filter was crashing when used by BSPlayer
(http://bsplayer.cjb.net)
* There was a parameter in encoder settings, which was called
"crispness" in the configuration dialog and "frame dropping" in the
help file. It is now correctly called "frame dropping" in the
configuration dialog.
* In the help file, on the page about post-processing, there was a
duplicate paragraph, written in a slightly different way. This
duplicate paragraph has been removed.
* The "About" dialog box of the codec showed an unreadable character
after the word "DivX." On machines with installed Russin it is a
trademark symbol, but there are lots of machines out there which do
not have Russian fonts. :-) This has been fixed.
* Added brightness, contrast, and saturation sliders
* Encoder now stores its settings in the registry
