TITLE: ActionMedia(R) II Drivers for Indeo(TM) Video
KEYWORDS: AMII, ActionMedia, Indeo
ActionMedia II Drivers Update -- Version 2.12-A2
The purpose of this updated version of the ActionMedia(R) II drivers is to provide
i750(R) hardware accelerated playback of Indeo(TM) Video files under Microsoft's
Video for Windows. This package includes the Indeo Video Driver V2.12, which
incorporates the software playback performance and image quality improvements that were
introduced in version V2.11. In addition, this Indeo Video driver supports hardware
acceleration of AVI files captured by Intel's Smart Video Recorder, including 320x240
resolution. Furthermore, driver support has been enhanced to provide hardware accelerated
playback of PLV bitstreams on ActionMedia(R) II. An additional feature was introduced
with Intel's Smart Video Recorder that allows the "raw" capture of video data and stores
it as uncompressed YVU9 data. The YVU9 Driver allows software playback of these
"raw" files.
UPDATE DRIVER KITS:
-------------------
There are 3 driver update kits available on Compuserve INTELACCESS Library 9 and on
Intel's BBS (916) 356-3600. The driver updates are packaged according to the type of video
accelerated hardware boards installed, i.e. ActionMedia II or RT Video. The Indeo Video
Driver V2.12 is included in all 3 packages.
If you have an ActionMedia II Board, then download AM2UPD.EXE.
If you have an RT Video Developer Kit, then download RTUPD.EXE.
Otherwise, for software playback download INDOVW.EXE.
NOTES:
1) These ActionMedia II drivers were originally posted May 11, 1993. This
update includes fixes to the reported installation problems. No additional
features have been added. Therefore, if you have successfully installed the
previous update, then you do NOT need to download this package.
2) In order to decrease the size of this update, we reduced the confidence
test file, DANCE.AVI to a 1 second clip. Thus, if you want to maintain
the larger file, rename it prior to running setup.
NEW AND UPGRADED DRIVERS
------------------------
* INDEO.DRV -- Intel Indeo(TM) Video Driver V2.12
INDEO.DRV has been upgraded to:
- Allow playback of files captured using the Intel Smart Video
Recorder, including 320x240 resolution.
- Provide improved support for analog keying.
- Provide improved support for PAL capture.
- Provide improved support for Microsoft PowerPoint, version 3.0.
- Provide improved support for Lotus Freelance, version 2.0.
- Allow for a lower Capture Key Frames default value: 1 (every
frame).
A sample Indeo video file is provided with the installation package. If
the sample video files are installed, select the Dance icon to view the
video.
* ISVY.DRV -- Intel YVU9 Driver
ISVY.DRV is a new Intel driver in the ActionMedia II driver package.
ISVY.DRV allows files containing data in an uncompressed video format
called "YVU9" to be played back in software-only mode in Video for
Windows. YVU9 files are captured by the Intel Smart Video Recorder.
* PLV2.DRV -- PLV 2.0 Driver
PLV2.DRV is a new Intel driver in the ActionMedia II driver package.
PLV2.DRV allows files containing data in Production Level Video (PLV) 2.0
format, to be played back in Video for Windows.
A sample PLV 2.0 file is provided with the installation package. If
the sample video files are installed, select the ConfPLV2 icon to view
the video.
To play back video, the PLV 2.0 files need to be converted from AVS file
format to AVI file format. You can access Intel's AVS-to-AVI conversion
program from Compuserve (Intel Access Library 9) or from the Intel
Bulletin Board Service ((916) 356-3600).
VGA BOARD COMPATIBILITY
----------------------
In addition to the existing 60-Hz VGA boards, VGA boards running at
the VESA 72.809-Hz standard can now be used with the ActionMedia II
boards and drivers.
NEW AND UPGRADED TOOLS
----------------------
* Configuration Program
The Configuration program has been improved to accept PAL-format video
capture.
* VIDRATE
VIDRATE is a new program that runs under Windows, and is used to
calculate the Vertical Blanking Interrupt (VBI) frequency. The VBI
frequency determines the exact synchronization rate of the installed
VGA board.
Use VIDRATE any time you:
- Change VGA boards.
- Change VGA drivers.
- Run utility programs that change the settings for your VGA
driver.
To run VIDRATE, perform the following procedure:
1. Open the "File" menu from the Windows Program Manager.
2. Select "Run."
3. Enter the path for the program; for example:
c:\am2\bin\vidrate
4. When the VIDRATE screen opens, select "Check VBI frequency."
VIDRATE may display a request to automatically correct the
INI file parameters.
5. If VIDRATE made INI file changes, run ALIGNVID to assure
proper video display alignment.
See VIDRATE's HELP screens for further information.
* ALIGNVID
ALIGNVID is a program that runs under Windows. This program allows you
to accurately align the VGA and hardware-assisted video for Indeo
video- or PLV 2.0-formatted data. To access ALIGNVID:
1. Open the "File" menu from the Windows Program Manager.
2. Select "Run."
3. Enter the path for the program; for example:
c:\am2\bin\alignvid
The ALIGNVID program opens displaying a red, dashed outline
of a VGA or XGA display over a grey box (ActionMedia II
display).
4. To align either the VGA (or XGA) or the ActionMedia II
display, click on the option, "Select alignments."
5. Select the appropriate option:
- "PLV, AMII apps align" for ActionMedia II display
- "VfW align" for VGA or XGA display
See ALIGNVID's HELP screens for further information.
KNOWN PROBLEMS
--------------
* Resolution Limitations:
- Maximum playback resolution size: 640x480
Other video modes are not guaranteed to operate properly
with the Indeo video drivers, and may result in misalignment,
green-shaded displays, system crashes, or other undesireable
system behavior.
- Maximum capture resolution size: 160x120
* No support for 75-Hz IBM standard VGA boards.
* No audio support. For audio capture or playback, a third-party audio
board must be installed into your computer. The audio is directed to
the audio board's WAVE driver when a file is played back.
* If you play back a file using ActionMedia II hardware, and the video
display is not correctly positioned in a Video for Windows window,
use ALIGNVID to properly align the video.
* If the monitor screen turns green when capturing video, or video playback
is jerky, run:
1. VIDRATE to check the VBI frequency.
2. ALIGNVID to check for proper screen alignment.
* If the quality of captured video is poor, verify the capture settings in
the Configuration program.
* In VidCap:
- In Overlay mode, when placing an iconized Media Player window
over the VidCap window and then moving the icon, a black
box remains on the VidCap window. This effect is cleared up by
clicking on the VidCap window.
- In Monitor mode, when a hardware-assisted video playback
window is moved on the screen, there is a slow response time for
redrawing the window.
* In VidEdit: when expanding a video window using the "Zoom 4x" option,
the video plays back only in software mode.
* In Media Player: when a software-only video window is zoomed by 2
and CTRL-4 is pressed, there is a slow response time for redrawing
the window.
* In PowerPoint: if the video display window size appears smaller than
the actual size, the alignment is off.
* In FreeLance: in Edit mode, a second video window opens when playing
the OLE video image.
