 Posted: Thu Oct 28, 2010 6:47 am Post subject: [Solved] WebCam and ZoneMinder |
 |
|
I am following the instructions at http://en.gentoo-wiki.com/wiki/Webcam to install my MSI 370i StarCam.
I have my kernel configured.
Everything seems to be in place but v4l-info complains about no /dev/video0
Any suggestions on where I am going wrong?
Plugging in the WebCam in, whilst booted gives the following /var/log/messages

| I had a similar problem, and experimented with the different drivers. Turns out that the driver that I thought was recommended for my hardware, didn't work with it, so in the end I settled on some older deprecated driver. Not much to go on for you, but hopeful helps a little bit. |

May have found the problem.
I did not use the correct driver.
I found the USB Device ID in /usr/src/linux/Documentation/video4linux/gspca.txt
and it indicates that I should be using sonixj driver, not sn9c20x (which I had selected).
I will try it out tomorrow.

Improvement but still no joy.
For ZoneMinder to build, I needed to ensure my /etc/make.conf MAKEOPTS had '-j1', not my usual '-j4', ZoneMinder does not parallel build, apparently.
ZoneMinder also would not compile unless I did | Code: | | export CPPFLAGS="-D__STDC_CONSTANT_MACROS" ; emerge zoneminder |
ZoneMinder also needs lots of shared memory, so had to add | Code: | #edit:fixed previously wrong prefix of sys.
kernel.shmmax=4194304000
kernel.shmall=2048000 |
to /etc/sysctl.conf (probably overkill with these numbers)
ZoneMinder required /etc/php/apache2-php5/php.ini to have | Code: | short_open_tag = On
|
or there are syntax errors in the cgi code.
For the WebCam (an MSI StarCam 370i)
v4l-info now shows the camera but mplayer won't play.  with a consequence that ZoneMinder doesn't work either
Getting closer though.

Ok, I got desperate.
I set every USB video driver in the kernel to Module.
Now, | Code: | # v4l-info
### v4l2 device info [/dev/video0] ###
general info
VIDIOC_QUERYCAP
driver : "sn9c102"
card : "SN9C1xx PC Camera"
bus_info : "usb-0000:00:1d.2-2"
version : 1.1.47
capabilities : 0x5000001 [VIDEO_CAPTURE,READWRITE,STREAMING]
standards
inputs
VIDIOC_ENUMINPUT(0)

Different driver, but still no joy with mplayer.
| Code: | # mplayer tv:// -tv driver=v4l2:device=/dev/video0:noaudio -fps 15
MPlayer SVN-r29796-4.4.4 (C) 2000-2009 MPlayer Team
Can't open joystick device /dev/input/js0: No such file or directory
Can't init input joystick
Playing tv://.
TV file format detected.
Selected driver: v4l2
name: Video 4 Linux 2 input
author: Martin Olschewski <olschewski@zpr.uni-koeln.de>
comment: first try, more to come ;-)
v4l2: your device driver does not support VIDIOC_G_STD ioctl, VIDIOC_G_PARM was used instead.
Selected device: SN9C1xx PC Camera
Capabilites: video capture read/write streaming
supported norms:
inputs: 0 = Camera;
Current input: 0
Current format: unknown (0x31384142)
tv.c: norm_from_string(pal): Bogus norm parameter, setting default.
v4l2: ioctl enum norm failed: Invalid argument
Error: Cannot set norm!
Selected input hasn't got a tuner!
v4l2: Cannot get fps
v4l2: ioctl set mute failed: Invalid argument
v4l2: ioctl query control failed: Invalid argument
v4l2: ioctl query control failed: Invalid argument
v4l2: ioctl query control failed: Invalid argument
v4l2: ioctl query control failed: Invalid argument
==========================================================================
Cannot find codec matching selected -vo and video format 0x31384142.
==========================================================================
v4l2: ioctl set mute failed: Invalid argument
v4l2: 0 frames successfully processed, 0 frames dropped.
Exiting... (End of file)

I tried various drivers for -vo (see -vo help), to no avail.

Got webcam to work using Mplayer https://forums.gentoo.org/viewtopic-t-854027-highlight-.html
Now trying to get webcam to work in ZoneMinder.
I have tweaked the ZoneMinder /etc/conf.d/zoneminder script as follows :-
| Code: | ZM_SCRIPT=/usr/bin/zmpkg.pl
# Commands for starting and stopping the server
if [ -x /usr/lib/libv4l/v4l1compat.so ]
then
preload="env LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so "
fi
CMD_START="${preload}${ZM_SCRIPT} start"
CMD_STOP="${preload}${ZM_SCRIPT} stop"
unset preload
|
but when I fiddle with zones in ZoneMinder, I do not see what the camera is seeing (using mplayer).
Suggestions welcomed

Searched for using | Code: | | grep -i 60c0 /usr/src/linux/Documentation/video4linux/* |
which pointed me to sn9c102.txt
Followed instructions on configuring that module.
Added sn9c102 to /etc/modules.autoload.d/kernel-2.6
Made sure I had both 'v4l' and 'v4l2' in my USE setting in /etc/make.conf
Did an 'emerge --newuse --verbose --with-bdeps y --update --deep world'
rebooted, just to be sure I had not borked my boot (which happens if I forget to emerge nvidia-drivers and virtualbox-modules)
Tested using | Code: | | mplayer tv:// -tv driver=v4l2:width=640:height=480:device=/dev/video0 |
Re-emerged ZoneMinder, just in case (temporarily changing my /etc/make.conf MAKEOPTS to '-j1' because zoneminder does not build well with parallel builds, apparently)
| Code: | | # export CPPFLAGS="-D__STDC_CONSTANT_MACROS" ; emerge zoneminder |
I had to put | Code: | | LD_PRELOAD=/usr/lib/libv4l/v4l2convert.so; export LD_PRELOAD |
in my apache2 /etc/conf.d/apache2
I had tried simply putting it in the zoneminder service startup script, to no avail.
ZoneMinder required /etc/php/apache2-php5/php.ini to have | Code: | | short_open_tag = On |
or there are syntax errors in the cgi code.
Restarted apache and browsed to the zoneminder page.
Now, I can see the webcam stream! (configured as 320x240 PAL RGB24)
