Event Montage unstable

[3esmit]

The Event Montage is a nice tool, but even if I change the filter date it still shows the same events. Also sometimes it says "invalid date" in the magenta background div.
Also it would be nice to always display the latest n events, not a time period. This way it can be used as a smart montage.

Can you help me understand this a bit more. The event montage is actually quite a heavy task on ZM - what happens is that for each window that shows up, apache launches an instance of nph-zms in ZM - each nph-zms streams one stream.

Questions:

a) When you change the filter date, what should happen is that the existing nph-zms instances get killed and new ones spawned in ZM which then stream new events - that takes a bit of time.
When you change dates, can you enable debug logs and see whats going on in logs ?

b) On the invalid date - I've seen it a couple of times - haven't zeroed in yet, if you find a predictable use case that produces this, do let me know.

c) Smart montage - I like the idea. I'll see what I can do there, Would you mind creating a new issue just for smart montage so I can tag a feature enhancement label on it

There is a true need of killing instances? Is possible to send a message to worker with new filter settings?
If you adding that feature of handy navigation buttons in timeline, would be nice if could just add the same code in event montage.

Yes unfortunately there is a need. The way zms of ZoneMinder works is it keeps streaming images over multipart/mixed. So unless I send a command to kill that zms, it will keep streaming data even when you destroy the DOM at the client side, resulting in massive data leaks. If I change any date/time params, I can't use the same zms instance - it is not designed to switch times. ZoneMinder/zoneminder#1253
