#as for how many cameras with
ionic needle
yes, queues are used
but for a single coral that is mostly moot
for multiple corals the queue becomes much more important

Stress testing: setting up a number cameras and subjecting them to a lot of motion and a lot and objects to see where and when when it breaks
ionic needle
yes, Blake has done that many times of the years he worked on frigate and again recently with 0.13 we did a lot of testing and iteration on object detection and motion detection making it more optimized and efficient

Cool.
I can't find a dropped frames sensor
looks like my max detection fps on one camera was 61
ionic needle
skipped fps
I actually have a graph on an HA dashboard that shows it for all cameras
blissful pulsar
Well a que would seen to eliminate dropped frames until the que is full even with one coral
ionic needle
no
because frigate is designed to run in real time
if it falls behind it will drop frames
because real time processing is the priority
blissful pulsar
at 6ms per inference for a coral if a second submission is made in less than 6 ms after a previous, it will be dropped or the process busy-waited.
ionic needle
ah no I don't think I was clear
I think we are describing the same thing in different terms
a queue is used, and it does have a max size
the max size is such that each camera does not fall behind more than 1 second from real time
blissful pulsar
ok that's reasonable. that's what I'd expect for an efficient process, is all the time critical code written in python or does it use compiled c/c++ libraries ?
ionic needle
it uses cython libraries like multiprocessing
