Bug#697854: general: Fail to display video

2013-01-10 Thread Ralph Ronnquist
Package: general
Severity: important

I just installed a fresh Debian 6.0, and got the problem that video doesn't
show, specifically in skype (neither preview nor call) and cheese (preview).

The webcam appears to work fine, since it shows up at the remote end on skype
call (but I see nothing here), and cheese captures pictures nicely.

Also, when I ssh from another host with ForwardX11, then skype (both preview
and call) and cheese preview show video on that host.

Thus, I'm guessing on something with X but don't know where or what.

The host is a Sony Vaio Z with:
00:02.0 VGA compatible controller: Intel Corporation Sandy Bridge Integrated
Graphics Controller (rev 09)

Well, as far as I can see it's a problem with the X server software 
rather than anything else, or the particular collection of packages I 
got on that installation. It happens with both cheese and skype, which 
are the things I've tried, while guvcview fails to run completely, with 
the note "Fatal:g_thread NOT supported' (a different problem).


Perhaps you would you be able to direct me to a better place to lodge 
this, if this is the wrong place?


regards,

Ralph.

Bug#697854: general: Fail to display video

2013-01-10 Thread Ralph Ronnquist
I'm afraid I have tried this; I have libv4l-0 installed, and tried the 
LD_PRELOAD variants as well. No luck :-(


The point is that it does work fine when displaying on another host via 
ssh with X11 forwarding (though skype needs LD_PRELOAD). (Possibly plain 
remote X11 as well, but I don't have that set up) This leads me to 
believe there's something with the X server subsystem.


In any case I need help to dig into it.

Ralph.

Please install libv4l-0 and copy this launcher
# aptitude install libv4l-0
# cp skype.desktop /usr/share/applications/skype.desktop

This should fix your issue and probably all those googling for
skype+debian+webcam

Cheers,
