Slow framerates on PV-149

startrk · Post by **startrk** » Wed May 23, 2007 9:19 pm

I have a Bluecherry PV-149 Zoneminder 1.22.3 on a P4 2.6GHz, 1Gb Ram, 250GB disk. The monitors are setup to run at 25fps but when you view the events it looks like zm is capturing at 5fps. The syslog show that each monitor is capturing and processing at 24.5fps. There are no errors in the syslog or zm logs. I have the bttv card=77,77,77,77 option on and dmesg reports

Any thoughts?

So what does ZM report the framerate is (check the logs, should tell you)?

This looks like the problem.

You need to change your modprobe file to bttv card=98,98,98,98

Actualy he don't need anything in modprobe as the card is properly detected by the bttv driver. I missed that you had insmoded the devices as 77. Thats wrong for this card and since it is auto detected, no need to insmod it, so you should remove the option in modprobe.

Well.. I reinstalled on top of Debian instead of Ubuntu using the .deb packages and the framerate problem has ended. Now the weird thing is when I reboot I get black screens in my monitors until I run xawtv. Then everything works great. Thanks for your help!!

My permissions are setup correctly. The monitors are not down but only show up with messed up black images. There are no persmission denied errors in the logs. www-data is in the video group. /usr/bin/zmfix has the correct permissions... It is like debian modprobes the bttv driver and zoneminder accesses it but it is running in PAL mode and won't switch out until I manually do it in xawtv. Is there a gbuffers tag I should add in my modprobe or default settings somewhere that set it to always use NTSC? Thanks for you time.
