Ubuntu 8.0.4.2, ZM 1.24.1, why is ZMA running on all of my cameras when they're all set to record aside from one of them that's on modetect? It seems to be eating a decent amount of CPU, and I don't understand why it's analyzing things if I tell it just to record them.

Code: Select all

ps -eaf | grep zma

zmc just captures the images and writes them to memory, zma is what writes them to disk from memory so even if you are just doing record then zma will be needed. It will not be doing analysis, but what might be taking some of your cpu is encoding the saved jpegs.

You could try some of the tips in this FAQ, particularly the libjpeg MMX one as people have reported very good results with that.
