Readme.txt for WDM Video Capture
July 1, 1997
1. Installing Testcap.sys
The first thing is to get Testcap.sys working. Testcap.sys is a sample
WDM video capture driver that produces a variety of test patterns such
as color bars and grayscale patterns.
To install:
- Start.Settings.ControlPanel.AddNewHardware
- No, Don't search for new hardware
- "Select the type of hardware you want to install"
Other Devices
- "Have Disk"
Browse to find "Testcap.inf"
- You may need to browse to find additional files required
2. Verify the following files are present on your system:
windows\system (or windows\system32 on NT)
ksuser.dll
ksproxy.ax
kstvtune.ax
ksxbar.ax
ksdata.ax
ksinterf.ax
kswdmcap.ax
ksvpintf.ax
windows\system32\drivers
ks.sys
stream.sys
testcap.sys
MYDRIVER.SYS
3. Loading the driver in GraphEdt.exe
- Make sure you're using AM2.0 GraphEdt.exe. This is needed to support
new PnP features.
- Graph.InsertFilters
- Category: WDM Stream Class Capture
"Testcap, Sample WDM video capture driver"
This loads Ksproxy.ax and connects it to Testcap.sys
5. Using Crossbar and TvTuner
The BT848 sample driver supports use of two additional AM filters for
TVTuning (kstvtune.ax) and Crossbar (ksxbar.ax).
5a. In GraphEdt:
- Graph.InsertFilters
- Category: WDM Stream Class TvTuner
