a few weeks zoneminder with black screen

[Swift71]

Hi, I'm a newbie and Dutch.
I have installed Zoneminder to watch swifts at their nest
Unfortunately, I get a black screen when the program is on.
Who can help me? I work with a pico2000card

when i read the log i see the next errors:

Code: Select all

2014-05-06 17:50:52.086520	zmdc	4084	ERR	'zmc -d /dev/video0' exited abnormally, exit status 255	zmdc.pl	
2014-05-06 17:50:52.083393	zmc_dvideo0	4139	FAT	Failed to get picture attributes: Inappropriate ioctl for device	zm_local_camera.cpp	540

In your /etc/modprobe.d/bttv.conf check for these lines:


alias char-major-81-0 bttv
options bttv gbuffers=32 card=77 tuner=4 radio=0 coring=1 full_luma_range=1 chroma_agc=1 combfilter=1 autoload=0 triton1=0 vsfx=0

Or have a look at this wiki page: Pico2000#ZoneMinder_configuration_2.0

check: stil dont work
Different errors

Code: Select all

2014-05-07 19:45:11.166840	zmdc	4434	ERR	'zmc -d /dev/video0' exited abnormally, exit status 255	zmdc.pl

The next commando worked for me: xawtv /dev/video0
but gives the next message

Code: Select all

This is xawtv-3.102, running on Linux/i686 (3.8.0-39-generic)

v4l2: WARNING: framebuffer base address mismatch
v4l2: me=(nil) v4l=(nil)
Alsa devices: cap: (null) (/dev/video0), out: default

but zoneminder gives still a black screen.
