Indeo(TM) Video Driver History under Video for Windows(TM)*
As of 11/15/94
Intel is constantly striving to provide customers with the latest
Indeo video drivers. With all the different versions coming out, it is
difficult to keep track of the latest version numbers. This article
tells what the latest version of the Indeo video drivers are under
Microsoft Video for Windows* (VfW) and gives the system.ini entry
for each driver.
Verifying version numbers
The version number of the currently installed Indeo video drivers can
easily be verified under Microsoft Windows. Go into the Control Panel
and bring up the Drivers applet. A dialog box comes up that lists all
of the installed drivers. The Indeo video driver will have an entry
similar to - "Intel Indeo(TM) Video RX.XX Driver". Double clicking on
a driver name brings up the driver's setup box. Listed in the box is
the complete version number for that driver.
Indeo Video Software Update History
The following sections list the Indeo video drivers that have been
released. The list starts with the newest updates and works its way
down to the oldest updates. The newest Indeo video drivers are always
available on CompuServe in the IntelArch forum (Go IntelA) library #9.
_______________________________________________________________________
Indeo Video R3.2 v3.22.01.044 with VfW 1.1d - Released: November 1994
This was an update posted by Intel. It is based on Microsoft's VfW 1.1d
update that was posted in October 1994 with a couple of improvements.
The Indeo video R3.2 driver was updated from V3.22.01.43 to V3.22.01.44.
The Raw driver was updated from V1.10.1.4 to V1.10.1.6.
The new Indeo video R3.2 driver had the following improvement over
V3.22.01.43:
- Fixed a potential problem with the floating point library not being
exited correctly while compressing a file.
The new Indeo video Raw driver had the following improvement over
V1.10.1.4:

Indeo video R3.2 v3.22.01.030 with VfW 1.1a - Released: June 1994
This was Intel's first Indeo video update that also included the latest
Video for Windows runtimes. It used a slightly modified version of
Microsoft's Setup utility to install the files. It contained the first
release of Indeo video R3.2. The new Indeo video driver provided the
following improvements over R3.1:
- Improved visual quality. There is significantly more foreground
and background detail for most sequences, particularly at 15 fps
with data rates of 135KB/sec or higher.
- Improved video playback performance at low data rates.
- Improved 16-bit image quality and playback performance.
- Improved audio playback at low data rates.
- Compression and decompression of images up to 640x480 size in
4-pixel increments.
- Improved software encoder performance.
- Faster initialization.
The indeov.drv "umbrella" driver was no longer used as in previous
releases. The R3.2 driver also handled playback of R3.1 compressed
files. A new Raw driver called iyvu9.dll was introduced. The same R2.1
driver was still used as in previous versions. However, the name was
changed from ir21_r.dll to ir21.dll.
Here are the Indeo video driver details for this update:
-----------------------------------------------------------
| Driver | Version | Filename | System.ini entry |
|--------|-------------|------------|---------------------|
| R3.2 | V3.22.01.30 | ir32.dll | VIDC.IV32=ir32.dll |
|--------|-------------|------------|---------------------|
| R3.1 | V3.22.01.30 | ir32.dll | VIDC.IV31=ir32.dll |
|--------|-------------|------------|---------------------|
| RAW | V1.10.1.4 | iyvu9.dll | VIDC.YVU9=iyvu9.dll |
|--------|-------------|------------|---------------------|
| R2.1 | V2.17.003 | ir21.dll | VIDC.RT21=ir21.dll |
-----------------------------------------------------------

VfW 1.1a with Indeo video R3.1 V3.12.040 - Released: March 1994
This was a Microsoft maintenance release. It was only posted on Microsoft
forums and BBSs. It updated the VfW runtime files from V1.1 to V1.1a. The
Indeo video drivers remained the same as in the VfW 1.1 release of November
1993. VfW 1.1a provided the following improvements over VfW 1.1:
- Simultaneous playback of two .AVI files was improved.
- Performance of video playback was improved correcting a
problem that caused shaky playback.
- A general protection fault (GPF) was fixed that could occur
when an embedded VfW 1.1 media object was clicked on in an
OLE 2.0 client.
- A slight memory leak that occurred with embedded objects was
corrected.
_______________________________________________________________________
Indeo video R3.1 V3.12.040 with VfW 1.1 - Released: November 1993
Two updates were actually released at this time. Different Indeo video
drivers needed to be used depending on which version of VfW was installed.
The VfW 1.0 update with Indeo video V3.11 was supplied by Intel and posted
on CompuServe. The VfW 1.1 update with Indeo video v3.12 was supplied by
Microsoft in their update.
R3.1 improvements:
- Added the CD-ROM offline compressor. The new compressor enabled
320x240 clips captured at 15fps to be compressed to less than
150K bytes per second.
The following chart provides the Indeo video version numbers and
filenames for VfW 1.1 and VfW 1.0:
-------------------------------------------------------------------
| Driver | VfW1.1 | VfW 1.0 |
|--------------|------------------------|-------------------------|
| R3.1 (IV31) | V3.12.040 (ir30.dll) | V3.11.041 (indeor3.drv) |
|--------------|------------------------|-------------------------|
| R2.1 (RT21) | V2.17.003 (ir21_r.dll) | V2.16.009 (indeo_r.drv) |
|--------------|------------------------|-------------------------|
| RAW (YVU9) | V2.17.003(ir21_r.dll) | V2.16.009 (indeo_r.drv) |
-------------------------------------------------------------------
VfW 1.1 INI file settings
-------------------------
Indeo video R3.1 used entries in two different files - system.ini and
indeo.ini.
System.ini entries:
[drivers]
MSVIDEO=isvr.drv
VIDC.IV31=indeov.drv
VIDC.RT21=indeov.drv
VIDC.YVU9=indeov.drv
Indeo.ini entries:
[GLOBAL]
DRIVERS=IV31,RT21,YVU9
[IV31]
DEC=ir30.dll
[RT21]
DEC=ir21_r.dll
[YVU9]
DEC=ir21_r.dll
The indeov.drv file was an "umbrella" driver. All of the Indeo video
VIDC entries pointed to indeov.drv. This file then looked at the entries
in the indeo.ini file that was created when the update was installed.
Indeov.drv grabbed the driver that was needed. The VfW 1.0 files did not
use the indeov.drv file nor the indeo.ini file.
VfW 1.0 INI file settings
-------------------------
System.ini entries:
[drivers]
MSVIDEO=isvr.drv
VIDC.IV31=indeor3.drv
VIDC.RT21=indeo_u.drv
VIDC.YVU9=indeo_u.drv

-----------------------------------------------------------------
Versions 2.1 and 2.12 were the only drivers with a complete feature set
of hardware/software decoding and software encoding capabilities.
V2.11 and V2.16 had software compression and playback. V2.17 only had
software playback. Both V2.16 and V2.17 had improved 8-bit color
dithering.
