Thanks Patrick -
It looks like that did compile against a different version of v4l, but
something doesn't seem right. When I run my node (it grabs frames from
a camera and does a few other things), I get:
HIGHGUI ERROR: V4L2: Failed to set control "9963802": Input/output
error (value 0)
HIGHGUI WARNING: Setting property 9963802 through v4l2 failed. Trying
with v4l1.
HIGHGUI ERROR: V4L: property #9963802 is not supported
HIGHGUI ERROR: V4L2: Failed to set control "10094850": Input/output
error (value 176)
HIGHGUI WARNING: Setting property 10094850 through v4l2 failed. Trying
with v4l1.
HIGHGUI ERROR: V4L: property #10094850 is not supported
and a bunch of
VIDIOC_QUERYMENU: Invalid argument
Am I doing something wrong, or is the ticket not actually resolved?
I'm using libv4l-dev 0.6.0-1 on Ubuntu 10.04.
Thanks,
-Dan
