This is what I have in my .ini file Jon: (word wrap off so it doesn't muck this
up)
EMBED_TAB_NAME = CAM_View
EMBED_TAB_COMMAND = camview-emc -c mycamviewcfg -g togle-caa.ui -H campins.hal
-w {XID}
Then mycamviewcfg (name is arbitrary as long as it has your setup) is:
<?xml version="1.0" encoding="utf-8" ?>

net cam5 camview.hal_button3 => halui.mdi-command-10
If its dark & blue, check whats associated with the V4L2 video format spec,
it might not be correct for that camera. Thats in the camviewcfg file.
My camera would be happier on a USB2.0 port, atom boards claim to have
only one USB2.0, but I've not found which one it is yet. Currently
plugged into a USB1.1 port on the front panel & obviously suffering,
but it does work. Just painfully slow. My Shoe box is high on a shelf
and the control box sits beside it, so I need a ladder to get up to
it and play with ports vs camera cable. I should look at the board
drawing that came with it perhaps? :)
I now have 3 tabs in the backplot window, backplot, bare dro, and camview now.
The dro also shows in the camview tab, but needs a background text color set,
hard to read when its mixed into the camera video.
I hope this helps more than it confuses.
Cheers, Gene
