I have a webcam in the studio of our radio station, and it hangs
sometimes. I want to try to pin down when this happens, and send myself an
email with the time etc so i can track down what's causing the camera to
hang. The webcam software uploads an image to the site every 30
seconds, so I
I know there have been links on a good How To on this topic, but
my google-fu is failing me. Can anybody point me in the right direction?
I don't have time to track down a specific reference, but this site
usually has good content for more advanced CF and JVM tuning.

Is there a CF image function or tag that will compare one image with
another? If not, is there a java function or something I can use?
I have made a CFX tag which calculates a CRC-32 checksum for a file.
If two files have the same CRC-32, probability that they are identical is very
high,
I think that the best way to do that would just be to do some sort of file
comparrison. There are many ways you could go about this. I think the three
most common are to compare the last modified times for the files, to
compare the files' size in bytes, and then to compare a fingerprint -
usually
This may seem like a stupid question, but what do you mean exactly
that the webcam hangs? You mean the software.. right?
If it's the software that hangs (since hardware can't really hang),
that means it doesn't upload a file or is it a different FTP program
that does it?
You could always set up
It may be easier to simply compare the file's date. Dates 60 seconds older
than now() and it's busted.

Thanks for all your helpful responses ...
@phillip:The symptom we get is that images are uploaded every 30
seconds ok, but at some point during the day instead of uploading new
images, it uploads the same image again and again. The problem is with
the computer that's providing the images,
Hrm..
Most software that allows uploads can also set the filename to the
time and date it was taken. Have you tried this? If so, I presume then
that the filenames stay the same as it doesn't take a new picture?

The filename is always the same, and the ftp software sets the creation
dates and mod dates correctly. Therefore we can't use any CFFILE-type
functionality
What we'll see is when you go into the station's webcam page, you can see
the current show host as he/she does his/her show - with an
Ok.. Time to go low tech.
1. Get a clock. Synch it up to the atomic clock (or at least to the
other computers as well).
2. Put it in front of the camera (make sure to post on the website why
this is so people don't get confused).
3. Next morning, check the page. The time shown is when it
Depending on what EXIF data gets written to the file, you might inspect it
using imageGetEXIFMetadata() and determine a change. Usually cameras will
drop the date taken in there, maybe your webcam does too.

Ok i have it figured out ... i can convert images to base64 strings,
which gives me a string I can manipulate using simple 'eq' operators.
So using a scheduled task, every 5 minutes, I take the current cabcam.jpg

I would look to a java solution. I am sure there is something within the
Java Image (I think that is the name of it...or be what I named the object
when I created it...been a long day... hehehe)that is capable of comparison.
