- Overview
- --------
- The purpose of this updated version of INDEO.DRV (V2.11) is to
- improve software playback performance. This Indeo Video driver supports
- software only compression/decompression. While it does not support
- playback on ActionMedia(R)II or RTVideo boards, it does provide support
- for software playback of video files captured by Intel's Smart Video
- Recorder, including 320x240 video.
-
-
- Installation
- ------------
- Indeo(TM) driver is distributed in compressed format as a
- self-extracting ".EXE" file. This file is named "INDEOZIP.EXE" and
- contains two files: INDEO.DRV and INDEO.TXT.
-
- To install this updated version of INDEO.DRV:
-
- To replace the older version of the Indeo driver:
- * move to the windows directory [e.g. c:\windows\system]
- * rename INDEO.DRV as a backup [e.g. indeo.old]
- * copy the new INDEO.DRV to the windows\system directory
-
- To verify the installation, use the Windows Control Panel, select Drivers,
- and double click on Indeo(TM) Video Driver from the list of Installed
- Drivers. The driver setup information will be displayed and it must
- report version 2.11.
-
-
- Enhanced Features
- -----------------
- Indeo(TM) V2.11 driver update contains the following enhancements:
-
- * Software Playback:
- Supports playback of AVI files captured using Intel's Smart
- Video Recorder.
-
- * Performance Improvements:
- Optimized algorithm for decode/color conversion to obtain the
- maximum performance on current x86 microprocessors.
-
- * Backoff Strategy:
- For a smoother picture during playback, improved the backoff
- strategy that determines when to drop frames based on a PC's
- performance. Autodetection of a PC's performance is
- determined and adjusted for in a matter of a few frames
- at the beginning of each file.
-
- * Zoom by 2:
- By directly implementing the "Zoom by 2" option, improved the
- playback performance of larger video resolutions.
-
- * RGB24:
- - Implemented full interpolation in Y, V and U, which improves
- the color quality image in high color mode. In addition, during
- video editing, VidEdit will receive a file in the high color mode,
- which in turn, will produce a better color quality image after
- editing than was seen with the previous Indeo Video driver.
- - Fixed bugs in the 24-bit code which improved both speed
- and color quality.
-
- * Encode Improvements:
- To be ensure that the compressor is configured for the same
- quality settings whether using software encode (via VidEdit) or
- hardware encode (via VidCap), a new dialog box was added. This
- dialog box allows the user under VidEdit to configure the compressor
- for 1 of 4 states, e.g. 0=Highest Compression, 3=Highest Quality.
- The quality slider provided by Microsoft in the Compressor Option
- dialog box has been disabled.
-
- * Bug Fixes
-
- Usage
- -----
- * Video Capture Optimization & Quality
- - For the best tradeoff between video compression and video
- quality, set the key frame rate to 3.
- - For the highest quality video and for highest quality playback,
- set the key frame rate to 1.
-
- Known Problems
- --------------
- Hardware
- --------
- 1. The playback of AVI files captured by Intel's Smart Video Recorder
- are software only.
- 2. This version of the Indeo driver is software playback only.
- Therefore, it does not recognize the video accelerator boards,
- such as ActionMedia II and RTVideo boards, and will disable
- the hardware playback option.
- [Note: these problems will be fixed in the next release of hardware
- drivers]
