Strange problem with video format

securstore · Post by **securstore** » Sun Apr 26, 2009 4:27 am

Its strange...in xawtv all ok, but when i change to zoneminder, all black screen...and when i back to xawtv, same thing, black screen..

I must stay changing between pal/ntsc/auto and rgb's YUV's types of video, to try made it works...sometimes works...somes no...

When i finded out the correct settings, i reboot the computer and then when i access the zoneminder...its just back to black screen!

Its 4 ntsc cdd cameras on a bttv card...

By the way, one of them stayed black and white...is that because de capture card?

I have two errors during boot about world writable /etc/mysql/debian.cnf and world writable /etc/mysql/my.cnf beying ignored!

zmwatch log:

its strange...if i uninstall zoneminder, cams back to work in xawtv....

OK! I find the problem....

Is this one:

See?? This is recognizing the video card like PAL.... ITS NTSC!

If i change to PAL in zoneminder, it works, but black-white and bad image...

If i change to NTSC, no deal!

How i fix it?

PS: i did this commands:

echo "kernel.shmmax = 268435456" >> /etc/sysctl.conf
echo "kernel.shmall = 268435456" >> /etc/sysctl.conf
echo 268435456 >/proc/sys/kernel/shmall
echo 268435456 >/proc/sys/kernel/shmmax

and after i did again the ./configure, but now with the --enable-mmap=yes option...

The camera works...until i reboot the system...

after reboot, no deal again...

supercharger:/home/supercharger# sysctl -p
kernel.shmall = 134217728
kernel.shmmax = 134217728
kernel.shmmax = 268435456
kernel.shmall = 268435456
kernel.shmmax = 35468950
kernel.shmall = 35468950
kernel.shmmax = 268435456
kernel.shmall = 268435456
kernel.shmall = 134217728
kernel.shmmax = 134217728

Please, i think now someone can help me!

Well...my final tip for someone help me:

1) I turn off zoneminder:

# /etc/init.d/zoneminder stop

2) i open xawtv:

# xawtv

3) i change PAL to NTSC in xawtv

4) I close xawtv and turn on again zoneminder:

#/etc/init.d/zoneminder start

5) And then THIS WORKS!

For Christ sake, someone can explain me whats going on?? How fix it to zoneminder works fine, without patchworks?

One of two things likely happening here.

Possibly you are using the wrong driver for the card.
It would display similar symptoms. ZM uses the image grab portion of the driver where xawtv just passes video to an overlay on the screen. You can simulate ZM in xawtv by trying to get a snapshot which does an image grab.

The other issue is that the recent kernels now uses V4L2 for the video driver and ZoneMinder has to use the V4L1 compatibility layer which don't seem to work right in certain kernels.

Kernel: 2.6.21-2-amd64
Really, Im using v4l2...

I have no idea as I don't remember what version they made the change. What does the software say?

"You can simulate ZM in xawtv by trying to get a snapshot which does an image grab":

Works flawlessly! It doesnt matter if is in ntsc or pal...the snapshot works normal...

Hint: if i sart xawtv and close it, when i open it again, i must make the change from pal to NTSC again...

If i stop zone, start xawtv, set to ntsc and close it and start zone, zone works...and then if i stop zone and open xawtv, have to make the pal/ntsc stuff all again..

Conclusion:

1) it doesnt matter if the xawtv change are done after or before zone works...i allways have to set it again.

2) If changing pal/ntsc in xawtv works, why in zone dont?
