-
- Improvements:
- -------------
- This version of the Indeo Video R3.2 driver is an update to Indeo
- Video R3.1 and Video for Windows V1.1. It provides:
-
- * 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. Note: 640x480x10 video with a 240KB/sec transfer
- rate, has been measured to play back at close to 10 frames per second.
- * Improved software encoder performance (2 to 5 sec/frame on a Pentium
- processor system).
- * Faster initialization.
-
- Indeo Video Drivers:
- --------------------
- Indeo(TM) Video R3.2 -- V3.22.01.30 incorporates the new Indeo
- Video R3.2 software codec that produces
- the highest quality video for software
- playback on Intel microprocessor based
- desktop computers.
- [filename: ir32.dll]
-
- Indeo(TM) Video Raw -- V1.10.1.4 incorporates the raw/YVU9
- codec.
- [filename: iyvu9.dll]
-
- Indeo(TM) Video R2.1 -- V2.17.003 incorporates a decompressor only.
- It plays back files created with the older
- R2.1 codec.
- [filename: ir21.dll]
-
- System.ini Entries:
- -------------------
- The Setup program installs the Indeo video drivers along with the
- latest Video for Windows runtime. It places the following entries in
- the system.ini file for the Indeo video drivers:
-
- [drivers]
- VIDC.RT21=ir21.dll
- VIDC.YVU9=iyvu9.dll
- VIDC.IV31=ir32.dll
- VIDC.IV32=ir32.dll
-
- Previously, the recommended system.ini entries looked as follows:
-
- [drivers]
- VIDC.RT21=indeov.drv
- VIDC.YVU9=indeov.drv
- VIDC.IV31=indeov.drv
-
- Indeov.drv was an "umbrella" driver that used a text file called
- indeo.ini to point to the various Indeo video drivers. The indeo.ini
- file had the following entries:
-
- [GLOBAL]
- DRIVERS=IV31,RT21,YVU9
- [IV31]
- DEC=ir30.dll
- [RT21]
- DEC=ir21_r.dll
- [YVU9]
- DEC=ir21_r.dll
-
- Indeov.drv and indeo.ini are no longer used and may be deleted if desired.
- However, older applications, which install the Indeo video drivers, may still
- use indeov.drv and indeo.ini. Since the name of the latest Indeo video driver
- has changed from ir30.dll to ir32.dll, this would prevent IV31 files from
- accessing the latest driver. To avoid this problem, an exact copy of the
- latest ir32.dll file, named ir30.dll, is also installed by this setup program.
- It is hoped the ir30.dll file will not be used. But if another setup program
- should change the system.ini entries to point to indeov.drv, then the correct
- driver will still be accessed through ir30.dll. In the future, this precaution
- should not need to be taken.
-
- Software Prerequisites:
- -----------------------
- * Video for Windows V1.1
- * Windows 3.1
-
- Optimum System Requirements:
- ----------------------------
- For the highest image quality and playback, the following system
- requirements are recommended:
-
- * Intel Pentium processor
- * System RAM: 12+ MB
- * PCI local bus graphics controller
- * SCSI hard drive
-
- For best frame rate performance, put the graphics card in 8-bit
- color mode. For best image quality, put the graphics card in
- 24-bit color mode.
-
- Based on the application and the size of the video file, some
- performance tuning of your computer's resources may be required.
-
