iCam Support / Re: CPU Usage

Thats it! The audio takes up most of the CPU. Without audio and 500ms interval it goes down to 4% and with 1000ms down to 3% which is pretty sweet.

Its interesting to note that with the build-in microphone it seems to use more CPU than with other sources like a USB microphone or the line-in its which is like 4% less, down to 8% total CPU usage.

Thanks for the help!

Thanks for your prompt reply!

I tested on a range of values between 500ms to 8000ms to find an approximately 2.0% CPU improvement between 500 and 8000ms intervals.

500ms   -> 13.5% CPU
1000ms -> 12.5% CPU
2000ms -> 12.0% CPU
4000ms -> 11.6% CPU
8000ms -> 11.5% CPU

Also, please note there was a jump in CPU usage every now and then (I think its period is the same as the interval) by about 0.5% CPU usage. So, for example, with the 8sec interval you could get an about constant 11.5% CPU usage which would then jump to 12% for a bit and then back down to about 11.4-11.5% which means something else is using up the CPU between intervals, it can't be the sleep counter using up 11.5% but I am not sure about the camera drivers, maybe having a feed from the cam open is expensive anyway...

If you can figure something out, it would be great, else I guess 10% is not the end of the world.

On Mac OS X simply make additional copies of the iCamSource.app and run each one, associating it with a different webcam input.

Thanks! This should do it.

iCam Support / Multiple cameras

Hi again

Is there a way to send information from multiple cameras using one computer (without using VirtualBox or something like that!)?

So lets say you have a couple of USB cams and a couple IP cams, can you use one computer to send all the information out?

Thanks

iCam Support / CPU Usage

Hi,

This is my first post here as I just got your app installed on my iPhone.

First of all, really nice app, well done!

But as always it could be even better. I noticed that my CPU usage for iCamSource, on my MBP, with Preferences closed, is about 12% constantly even when I view or not view the video from my iPhone and irrespective of the sensitivity set on the motion detection.

It would be pretty cool if you could reduce that 12% to something a lot lower, maybe half? With the sensitivity lowered you could reduce the framerate as well as the resolution of the images using in the motion detection (I am sure you already use binary images for the motion detection). Then, when an iPhone is connected and streaming is established, or when a motion event recording initiates, the framerate and resolution would increase. This way you would spend minimum resources (reduce power consumption, heat, reduce carbon footprint! etc.) when nothing is happening or no one is watching.

All the best,
Vasilis
