Introduction
------------
**The Playa**
The Playa is the media player of choice for DivX content. New features
include higher performance and visual quality, progressive download so
you can playback before the download is complete, and the ability to
play broken AVI files. From the people that brought you DivX(tm) video
technology.
**The DivX Codec**
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!
**The Validator**
The Validator will check the directory of your choice for "Authentic"
DivX files. If it truly is a DivX file it will rename the file
extension to *.divx. Why? Well there is a ton of content encoded in
DivX and we know that this content is hard to find through search
engines because right now it uses the *.avi file extension which could
really be any codec. We also know that there are individuals who
actually place "DivX" in the name of their files when they are truly
not DivX so that you will be more inclined to download it, since
"DivX" is known now as content that is encoded with High Quality.
Well we want to make sure that content that is truly is DivX is easy
to find and that the DivX name lives on.
Installation instructions
-------------------------
To install the Playa, Codec and Validator, you should follow the
following simple steps:
1. Copy the installer program (DivX4Bundle.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
The Playa.
4. Done! The Playa, CODEC, and Validator should be installed in your
Systems directory.
**What files are installed?**: The Playa installer will install the
following files on your system:
* ThePlaya.exe (DivX Player executable)
* divx.dll (DivX Codec)
* divxdec.ax (DivX Decoder Filter)
* Help.chm (DivX Help File)
* Validator.exe (Validator executable)
* 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 Codec" and click "remove."
DivX encoding and decoding
--------------------------
How do I use this thing? Please refer to the Help File included in
the installer. You can find the help file in Start -> Programs ->
DivX -> DivX Codec -> Help
Using the Validator
-------------------
Just double click the validator on your Programs menu and the
Validator will do the rest. It will, upon request, rename all files
with a DIV3, DIV4, and DIVX FOURCC code to use a *.divx extension.
This removes the ambiguity associated with the *.avi extension.

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
**Change Log:**
-- Changes since beta 1 --
* DivX DirectShow filter was not working 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 / Celeron machines (
a few SSE instructions were accidentally put into MMX YUV->RGB
conversion routines )
* Decoder was crashing with postproc level 6 or 7 and 16*N < height <=
16*N+8.
* Fixed one 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 config dialog and 'frame dropping' in help file. It
causes a lot of confusion.
* In the help file, on the page about postprocessing, there was a
duplicating paragraph, written in slightly different ways.
* 'About' dialog box of the codec showed an unreadable character after
the word 'DivX'. On machines with installed Russian it is a 'TM' sign,
but there are lots of machines out there which do not have Russian
fonts :-)
* Added brightness, contrast and saturation sliders.
* Encoder now stores its settings in the registry.
-- Changes since beta 2 --
* 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
-- Changes since beta 3 --
* Fixed more problems with decoding 3.x
* Removed last SSE instruction from YUY2->YV12 MMX conversion function
* Added sanity checks for log file contents
* DirectShow filter was not applying brightness/contrast/saturation
settings when starting playback
* Reverted DirectShow filter overlay operation to beta2 style due to
reports about decreased performance on some computers
* Fixed few problems in 2-pass VBR ( sorry guys! )
* Fixed memory leak at highest postproc levels
* Fixed bug with coding as 'skipped' macroblocks that differ only in
chrominance
* Fixed buffer overflow in decoder
* Purple areas were appearing sometimes near right edge of picture ( bug
in encoder )
* Added support of log file format version 2 ( should add minimal
ability for external programs to control 2nd pass )
* Encoder assumes that 1 kbps = 1000 bits per second
* Crash with YUY2 output, height=16*x+2, width!=16*x
* More fixes for decoding 3.11 with non-16*x dimensions
