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
|
||
|
|
- Category: WDM Stream Class Crossbar
|
||
|
|
|
||
|
|
5b. To change Tv Channels:
|
||
|
|
Bring up the properties page on the TvTuner filter
|
||
