Control Webcams

I got it figured out how to get HB to control webcams. It works for my set-up pretty good. The attached zip file includes most of the needed stuff. The only part not included is an SDK that needs tp be downloaded from MS.

Not sure what I'm missing...

Win2k SP4
Running HB 2.32
C:\Program Files\HouseBot

the first command runs correctly and shows video devices,
but the second command puts out an error
"Invalid profile: 0x80070057 The parameter is incorrect."
C:\WMSDK\WMEncSDK9\samples\vb\wmcmd>
cscript.exe wmcmd.vbs -devices

Did you both install the:
WMEncoder.exe
WMEncoderSDK.exe
?

If you didn't install the first one (I forgot that too), it won't work!

Yup that was it !!!

Now if I can keep HB from crashing (no error) every time I try to test the cams...

Sigh

Thanks for the help !!

Using that same script, I also have HB crashes each time I run this script. So I used the standard windows script and built another shell around it using the External Control device.
I don't have it operational because I wanted still pictures in stead of motion pictures. However I still have it installed on my test PC.

So Richard

I'm asking
Please

can I get a copy or take a look at your windows script and the shell?

Thanks

Kris

What I was saying was that I just used the windows script that comes with the sdk. I didn't use the modified script for HouseBot since it only works once and then I have to restart HB.

The shell is nothing more than starting this script using the external command. The external command runs when a task triggers (like when someone presses the doorbell). The task will set the Arguments portion of the external command and in this argument the proper cam and recording time as well as the filename it should produce is set.
The examples are stored on my test PC which I don't have access to right now, but it should be fairly simple once you are able to run the script using the external command.
By external command I refer to the Execute Program Device.
