hi!
i've configured 1.22.3 in a ubuntu server.
with any of 3 different cams i can't get more than 1.50 fps.
cpu usage is low and this is the output of hdparm:
Code: Select all
# hdparm -tT /dev/sda
/dev/sda:
Timing cached reads: 420 MB in 2.00 seconds = 209.61 MB/sec
Timing buffered disk reads: 74 MB in 3.04 seconds = 24.37 MB/sec
what can i do for increasing FPS? where is the bottleneck?

I suspect the capture card. What are you using to capture the cameras?

sorry, i forget to say i'm accessing network cameras.
all of three can achieve 25fps, but 10 is enough for me

what network cams and i assume at that framerate your using jpeg grabs. I used a 206 that can do 25 fps on jpg grabs so i know zm is up to it. My early supposition is that your cams can not

the cameras are:
- axis 2100
- pixord 201p
- conceptronic cnetcam
i've changed the computer and now i can get 8 fps but seems that i've reached some internal limit.
i've tried to set any fps limitation to a higher value but no success, is there any limitation of 8 fps?
