Which platform/OS is this with? Which version of ARToolKit.

If on windows, you need to edit the camera config file (WDM_camera_flipV.xml by default) so that there are configurations for both cameras.

Hi!

I have two cams that are listed on Windows as:

- Creative WebCam NX
- VideoCAM Messenger #3

And my WDM_camera_flipV.xml:

<?xml version="1.0" encoding="UTF-8"?>
<!--Sample XML file generated by XMLSpy v2005 rel. 3 U (http://www.altova.com)-->
<dsvl_input xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="C:\Documents and Settings\Thomas\My Documents\projects\ARToolKit &amp; DSVideoLib\ARVideoLib\DsVideoLib\DsVideoLib.xsd">
<camera show_format_dialog="true" friendly_name="PGR">
<pixel_format>
<RGB32 flip_h="false" flip_v="true"/>
</pixel_format>
</camera>
</dsvl_input>


I don't know how to configure. Where i can see the "friendly_name" ?

Try something like this:

<?xml version="1.0" encoding="UTF-8"?>
<!--Sample XML file generated by XMLSpy v2005 rel. 3 U (http://www.altova.com)-->
<dsvl_input xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="C:\Documents and Settings\Thomas\My Documents\projects\ARToolKit & DSVideoLib\ARVideoLib\DsVideoLib\DsVideoLib.xsd">
<camera show_format_dialog="true" friendly_name="Creative WebCam NX">
<pixel_format>
<RGB32 flip_h="false" flip_v="true"/>
</pixel_format>
</camera>
<camera show_format_dialog="true" friendly_name="VideoCAM Messenger #3">
<pixel_format>
<RGB32 flip_h="false" flip_v="true"/>
</pixel_format>
</camera>
</dsvl_input>
