Problems with external webcam

[Jones-S]

Hi
I have another problem:
I am on Mac OS X 13.3 and I use reacTIVision 1.5 (the last released version).

It works alright with the built in laptop webcam, but if I want to use an external logitech 1080p cam, I can't get a proper input image.

I tried to work with the camera.xml:

<?xml version="1.0" encoding="ISO-8859-1" ?>
<portvideo>
    <camera id="0">
        <capture width="640" height="480" fps="max" compress="false" />
        <settings brightness="default" contrast="default" gain="default" shutter="default" exposure="default" sharpness="default" gamma="default" focus="default" />
        <frame width="max" height="max" xoff="0" yoff="0" />
    </camera>
</portvideo>

Results in this:
4* the camera input, squeezed in y-axis and leaving a lot of black space. (you can see my hand)

I tried the -l startup option to list all cameras:

./reacTIVision -l

But even if I adjust the settings to this:

<?xml version="1.0" encoding="ISO-8859-1" ?>
<portvideo>
    <camera id="0">
        <capture width="1920" height="1080" fps="max" compress="false" />
        <settings brightness="default" contrast="default" gain="default" shutter="default" exposure="default" sharpness="default" gamma="default" focus="default" />
        <frame width="max" height="max" xoff="0" yoff="0" />
    </camera>
</portvideo>

I get an even weirder image:

When running hitting the o shortcut, which should bring up the camera options does not work either.

If there was anybody who has experience something similar or has another hint, I would be very glad to hear that.
Cheers

Oh also I get this information when starting via Terminal:

$ cd reacTIVision.app/Contents/MacOS 
$ ./reacTIVision
