AXIS 206W fps issue

well... i used mjpeg before but it appears jpeg is easier on the system, i have a 206m that was on mjpeg then i changed to jpeg

load was over 4 usually on it now is around 1 so i think your right mjpeg is harder on the server

ahhhh,

ok....shit i changed all my stuff to mjpg....

ok, guess i switch back...

the biggest problem i'm fighting as of now is that the ip-cams get changing reception...

i run pingplotter and sometimes i get 400ms and then of course errors from zoneminder telling me that the device did a timeout..

usually they run 2ms to 10 ms....i guess that my wirelless connection drops once a while...

do you have the same problem ?

can you tell me the status of your asis cam ?
there is a menu which tells you speed and reception....(under setup/wireless)

thanks,

ive never used wirless cams but you could increase the timeout in settings

Regarding the path depends on what you want mjpeg gives a higher framerate but at the expense of more load so it depends on what your doing with them

There is no reason at all why mpjpeg should be harder on the system than jpeg except that individual jpegs are requested one at a time which takes time during which nothing is happening. If you have limited your camera to serving images at a fixed frame rate then, if anything, mpjpeg should be lighter on load as it doesn't have to ask for each one.

The only other difference is that in mpjpeg format zms has to determine the end of one frame and the start of another but so long as your camera hints it with a content-length header it should not take any more effort.

Hi all,

I appreciate all of your help by I am still experiencing problems.

I can't even get the still JPGs to flow anymore.

The symptoms that I am experiencing when viewing the camera output from ZM is I get a black box for about 10 seconds, I then get 1 picture at
640x480 but it is really pixelated, it then sits with the first picture on the screen and I don't get any other output from it.

Just as an aside, if I wanted to reference an image (screen dump) how do I do it in this forum interface? (or do I just have to email it)

Thanks,

Vypre

vypre,
What does your log say?
Have you searched the forum?
What have you tried?
Did you remember to restart zm after any changes to the camera settings?

Regards,
Corey

vpre,

can you view the output of the cam using a browser ?

e.g.

http://cam-ip/axis-cgi/jpg/image.cgi?resolution=640x480

and do refresh to get new images ???

Hi,

Experimenting with an IP camera for the first time. I am using an Axis 206W (which by the way seems to use Linux - a good reason to choose Axis in the future as well

ZM monitor window does not show any picture at all. I have tried all the possible configuration settings I can think of.

I am able to stream the video feed from the cam using this path:

http://192.168.1.45/axis-cgi/mjpg/video ... 5869555744

I am even able to stream the same feed to another PC at the same time, even using 640x480 resolution, so bandwith does not seem to be a problem.

Reg exp is turned on in ZM Options and ZM restarted.

Hi All,

I have finally got the /mjpg/video.mjpg link working (for some reason it didn't work before). It takes about 30-40 seconds before I get anything on the screen when viewing it.

I have tried changing the mode from Monitor to Modect and it doesn't make any difference. I am still getting 1.1 FPS.

This problem is apparent on 2 installs that I have done of this, 2 separate cameras, 2 separate servers, 2 separate networks.

Bandwidth shouldn't be an issue as the networks are 100Meg to a Gig. I have tried almost every option with NO effect.

Something that I don't think I mentioned before is that I am using the LIVECD, are there any known problems with this? It just makes building the boxes brainless and quick.

If you need any more info, I can post it up again.

Thanks.

ok, some updated information (a little weird mind you).

I played with the settings last night quite a bit but finally decided to go to bed. I have gotten up this morning and it is now
saying that it is capturing at 10FPS BUT when I view the camera I only get the first frame (which is VERY pixelated) and thats it.

The only real thing that I changed last night was the MAXFPS setting on the ip camera itself, the camera device in ZM
and the setting in High b/w (I set them all to 10fps).

I have also changed my URL to /mjpg/video.mjpg?req_fps=10.

Any ideas as to what this issue might be with the stuck frame? (I can supply a picture if needed)

Have you tried just using the exact same url in ZM that you have used from your browser? Also perhaps try using wget from your ZM box to test the urls as well.

Hi,

thanks for the reply. I have actually fixed this issue and have logged another question about some other issues that I have.

Part of the problem was that there are 3 places where you set the MAXFPS, one in the ZM Options, one in the options for the actually IP camera and the last is in the camera device in ZM. Once I got all of them the same things started working better.
