It's built in to LinuxCNC.
I just added this to my INI file [DISPLAY] section:
EMBED_TAB_NAME= cam_align
EMBED_TAB_COMMAND= qtvcp -d -c cam_align -x {XID} cam_align
And this is the same, a show stopper but the error msg is more specific,
so It might be progress.
It now errors and quits with:
camera-postgui.hal:1: Pin 'mm_xacc.max' does not exist
Shutting down and cleaning up LinuxCNC...
Running HAL shutdown script
This is the 4th variation of the EMBED_TAB_COMMAND I've found tonight,
none of which worked.
camera-postgui.hal has as line 1, the first of about 25 lines, all of
which will be showstopper errors
because the 3rd argument of each "net" line in it, does not exist.
And all the missing mm_0nets there are sourced in check_constraints.hal,
which is not included in any
postgui.hal reference. If its supposed to be, document it!
Andy, or whoever might be the expert, there ought to be ONE install.txt
in that zip, describing once
only how to install this so it Just Works (with a compatible camera of
course) but there's no such
complete help file that I've found. And I never did find a hit that
would give me a fresh copy of this
5 or 6 year old cam_align.
And you can't just fix a typo and retry it, because that failure leaves
all of qtvcp running
which ties up the video ports it needs until you call up htop, find it
and kill it.
The camera works well, with cheese or v4l2. Why does it not work with
linuxcnc?
And the LinuxCNC config running in a VM on my Mac started displaying the
webcam image from the built-in Mac camera. (which I am rather surprised
worked)
Cheers, Gene Heskett.
