Also, does yours work for more than... say... 30 seconds? Mine goes to a black screen after about 15 seconds and the log shows:

Feb 20 15:38:42 sandbox zms[6626]: WAR [Unable to store frame as shared memory invalid]

shmall = 1048576000
shmax = 4194304000

I don't believe thats a problem caused by the format because here i let it run for 5 minutes and it worked just fine.
check the system log for more errors such as not being able to initalize shared memory.
By the way your shmall is too high. keep in mind its not in kilobytes but pages and the default value is 8 GB:

I checked a little and it seems this error doesn't orginate from ZM, but rather from libjpeg, which zoneminder uses for decoding jpeg images.
Your camera probably streams slightly corrupt\broken images, but as long as they work in ZM, i think its OK to ignore that warning.
If you want you can recompile libjpeg to remove that warning, or even easier, set up a syslog filter against this warning.

Thanks! Other than that my only issue seems to be with shared memory--- I read a lot about it last night and tried about 20 different settings-- everything resulted the same-- blank screen after about 20 seconds

Hi.

After some searching in this forum it appears this error seems like a known problem with no fix, not really related to shared memory.
Few things you might want to try that worked for others:
1) Reduce fps (try 5?)
2) Increase HTTP timeout in Network->Options to 5000
3) Try switching between HTTP/1.1 and HTTP/1.0 in Network->Options.

I can't reproduce it, it happily works here (tested 15 minutes)

Since switching it to 6fps, it works flawlessly =)

Thanks! I didn't ever notice the thread you found, but searched a LOT.

Thanks for all your help man.
