using video(4) Chicony CNF7051 fails after first success

["Jeremy C. Reed" <reed%reedmedia.net@localhost>]

I have:

uvideo0 at uhub2 port 2 configuration 1 interface 0: Chicony Electronics 
Co., Ltd. CNF7051, rev 2.00/8.34, addr 2
video0 at uvideo0: Chicony Electronics Co., Ltd. CNF7051, rev 2.00/8.34, 
addr 2

ucview-0.22 from pkgsrc uses it fine the first time. A blue light turns on
and the live video starts displaying to my screen. Looks good.

But when I choose "Change Device" and use same device -- or when I exit 
and reopen ucview, it no longer shows video. I restarted X and that didn't 
fix it. I rebooted and then it worked again (one time then failed on 
restart or reconfigure of ucview).

On console I see:

(ucview:725): Gtk-WARNING **: GtkSpinButton: setting an adjustment with 
non-zero page size is deprecated

(ucview:725): Gtk-WARNING **: GtkSpinButton: setting an adjustment with 
non-zero page size is deprecated

(ucview:725): Gtk-WARNING **: GtkSpinButton: setting an adjustment with 
non-zero page size is deprecated

(ucview:725): GConf-CRITICAL **: gconf_client_set_string: assertion `val 
!= NULL' failed

I don't know if that is related.



I also installed frameworks. It doesn't display anything.

And I installed xawtv which also includes webcam and v4lctl.

Documented v4lctl --device=/dev/video0 errors, but -c does something:

$ v4lctl -c /dev/video0 list
no grabber device available

Or:

$ xawtv -c /dev/video0
This is xawtv-3.95, running on NetBSD/amd64 (5.0_RC3)

I didn't try ekiga or cheese yet since don't have gnome...

Any ideas?

Anyone using same device?
