- 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 v3.22.01.030 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.
-

- mean in the previous chart:
-
- --------------------------------------------------------------------
- | Terms | Definition |
- |-------------|----------------------------------------------------|
- | H/W decoder | hardware playback using i750* chip set (i.e., with |
- | | ActionMediaII* card) |
