Have you tried configuring all your cams/inputs then restarting ZM?

gianrubio · Post by **gianrubio** » Tue Jan 20, 2009 12:27 pm

the same problem with all camera setuped and the zoneminder and server restarted

gianrubio · Post by **gianrubio** » Tue Jan 20, 2009 2:43 pm

more info
if i setup only one camera like /dev/video0 (0) the zm show the cam,
when i setup one camera like /dev/video0 (1) the zm bug wiht float exception

i think is the driver of bt878 is the problem, but with xawtv all camera simultaneous are ok

sorry about mistake
i have wrong config of cameras
/dev/video0 (0)
/dev/video0 (1)
/dev/video0 (2)
...
the correct is

/dev/video0 (0)
/dev/video1 (0)
/dev/video2 (0)
/dev/video3 (0)
...

Isn't that relevant?

just change this:

usleep( (1000000 * ZM_RATE_BASE)/(base_fps*abs(replay_rate*2)) );

to this:

usleep( (1000000 * ZM_RATE_BASE)/((base_fps?base_fps:1)*abs(replay_rate*2)) );

It's a divide by 0 exception where the base_fps was 0. Nothing was written into the buffer since the last time this function was called. Mine did that because I was intentionally slowing down capture when zm was disabled.

solved with the correct configuration

changed from

/dev/video0 (0)
/dev/video0 (1)
/dev/video0 (2)

to

/dev/video0 (0)
/dev/video1 (0)
/dev/video2 (0)
/dev/video3 (0)
