Ubuntu 12.04.03 LTS , USB Video Capture Device busy ?

[selfmade]

Hello Group,

I have installed ZoneMinder 1.25.0 as described in ' janhellevik com / ?p=1045 ' on my Ubuntu 12.04.3 LTS Server.
Ubuntu running on VirtualBox.
My camera is an analogical surveillance camera.(no IP. no direct USB-WEB-Cam).
The camera is with Hauppauge USB adapter connected on my PC. And my PC have USB 3.0 and 2.0 ports.
I've tried both.
In the Virtaulbox I have USB enabled.

The following messages are on

lsusb:

my host-system is win-7. (Ubuntu is Guest)

i don't believe USB-Port or the camera is busy.
No other Software use the camera.

what i can do?

best regards

Setting Zoneminder aside for a minute, can you see the output from the camera in something like VLC or tvtime etc. that can access a Video For Linux device?

Or something like ffmpeg to grab from it by hand if you don't have them installed.

(Something like ...)

ffmpeg -aspect 4:3 -s 640x480 -vc 1 -tvstd PAL -f video4linux2 -i /dev/video0 -r 25 -t 10 -vcodec mpeg1video -bufsize 50Mi -b:v 5000k -minrate:v 1000k -maxrate:v 8000k -f mpeg outputfile.mpg

-vc 1 is the channel number (you may need 0, 1)
-r 25 frame rate
-t 10 capture for 10 sec and stop

i get this with udevadm

udevadm info -a -p $(udevadm info -q path -n /dev/video*) |grep ATTR{name}

ATTR{name}=="cx231xx #0 video"

and zmu give me this output

zmu -d /dev/video0 -q -v
Error, failed to query crop /dev/video0: Success

mmmh?

Doh. You have stepped in some silly argument between rival groups of developers. FFMPEG is not deprecated, it is alive and well and supported, you just need a distribution that isn't getting stuck in the middle of someone else's wars and picking the "other" side.

I meant a genuine install of ffmpeg from the real developers, not this hacked about thing. Sorry

What about VLC? (Assuming they haven't decided that it is in someway inferior ... and replaced it with something else claiming to be vlc)

Real FFMPEG is here http://www.ffmpeg.org/ and VLC, if you don't have it, is here http://www.videolan.org/

hello
i tested already with VLC but syslog told me, the device is busy...

i use virtualbox
and windows is the host, but not any win-tool use the camera.
but i can't hang out the USB-device on windows...

any idea?

best regards

maybe i have only this problem with the USB-Video connector.
(this is a testing-system... later i will use a pci-8-channel Video capturecard

As root, what does this command get you (mine shown below IS in use, by tvtime ...)

Code: Select all

lsof /dev/video0 

COMMAND  PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
tvtime  2761  mjb  mem    CHR   81,0          4049 /dev/video0
tvtime  2761  mjb    4u   CHR   81,0      0t0 4049 /dev/video0

If it returns nothing, then Linux doesn't think anything has got /dev/video0 open.

Hello,

this is the output from lsof

achim@SB-Comgate:~$ sudo -i
root@SB-Comgate:~# lsof /dev(video0
lsof_ Warning: can't stat() fuse.gvfs-fuse-daemon file system /home/achim/.gvfs
Output information may be incomplete.

if i start lsof under user=achim
output is empty

That output confuses *me*. So it sure as heck isn't going to please ZoneMinder.

As an ordinary user though, it shows nothing using it, so I suspect that nothing within Linux *is* using it.

Not having tried using VMs e.g. VirtualBox, I'm not sure where you go from there -- the problem doesn't appear to be ZoneMinder itself, if VLC also complains. It's the VirtualBox/underlying host giving you grief.
