Save pre-event from external command

[camalau]

Hello everybody!

I configured a camera's buffer to 20 seconds pre-event, I would like to externally save these 20 seconds, is there any way to do this via command or something? Because when I use "zmtrigger" it only generates the moment I send the command, not saving the 20 seconds before the command.

Thanks

I don't think there is an easy way to capture the pre-event frames. Well not within Zoneminder, you could manipulate the event output post capture with a script.

A triggered event SHOULD have the pre-event frames. I'll take a look at the code... but.. unless there is some other misconfig, they SHOULD be there.

Ugh... the code too hairy for me to grasp tonight.
