Hey guys,

I'm working on a project that uses color tracking in GEM at the core of its process and I've managed to get the feeds from two fire-i webcams but for some reason I can't seem to lower the resolution.

As in, unless I set "dimen 1200 1600" I either get a cropped portion of the video feed or some sort of green pixel-y mess when I try anything else.

I've tried going into the dialog box but the settings just don't seem to stick. Even the preview window only shows a fraction of the video input.
The default setting seems to be: "Component Video CCIR"

Any ideas?

It's seriously eating up the cpu load and like, being a bit of a hassle.

Any thoughts?
I'd greatly appreciate any help!

Owen.

thats weired
i did a project with unibrains on XP some time ago and they had a resolution of 640x480.
it worked great, i could display 4 of them at a time.

you use pix_video, i guess?

yup!

It's super weird.

[pix_videoDarwin]: using RGB
[pix_videoDarwin]: height 480 width 640
[pix_videoDarwin]: starting reset

[pix_videoDarwin]: digitizer rect is top 0 bottom 1200 left 0 right 1600
[pix_videoDarwin]: active src rect is top 0 bottom 1200 left 0 right 1600

that's kind of the extent of the messages and I don't really know what to make of it. What's with all that HD jazz? I certainly don't want that.

but yeah, so far, I can only get 1200 1600 and higher. Maybe if I worked in YUV?

edit: I forgot to mention that I'm running a macbook pro with snow leopard.

another thing i remember is that it didnt work with the unibrain drivers (on XP)
i had to remove the drivers and use the generic DV driver...
but i guess thats of no use for you also...sorry
