This is still pretty basic support. There's no config UI support for
renaming/moving the sample file directories after they are created, and no
error checking that the files are still in the expected place. I can imagine
sysadmins getting into trouble trying to change things. I hope to address at
least some of that in a follow-up change to introduce a versioning/locking
scheme that ensures databases and sample file dirs match in some way.
A bonus change that kinda got pulled along for the ride: a dialog pops up in
the config UI while a stream is being tested. The experience was pretty bad
before; there was no indication the button worked at all until it was done,
sometimes many seconds later.
This allows each camera to have a main and a sub stream. Previously there was
a field in the schema for the sub stream's url, but it didn't do anything. Now
you can configure individual retention for main and sub streams. They show up
grouped in the UI.
No support for upgrading from schema version 1 yet.
