There may be considerable lag between being fully written and being committed
when using the flush_if_sec feature. Additionally, this is a step toward
listing and viewing recordings before they're fully written. That's a
considerable delay: 60 to 120 seconds for the first recording of a run,
0 to 60 seconds for subsequent recordings.
These recordings aren't yet included in the information returned by
/api/?days=true. They probably should be, but small steps.
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.
The Javascript is pretty amateurish I'm sure but at least it's something to
iterate from. It's already much more pleasant for browsing through videos in
several ways:
* more responsive to load only a day at a time rather than 90+ days
* much easier to see the same time segment on several cameras
* more pleasant to have the videos load as a popup rather than a link
that blows away your position in an enormous list
* exposes the fancier .mp4 generation options: splitting at lengths
other than the default, trimming to an arbitrary start and end time,
including a subtitle track with timestamps.
There's a slight regression in functionality: I didn't match the former
top-level page which showed how much camera used of its disk allocation and
the total duration of video. This is exposed in the JSON API, so it shouldn't
be too hard to add back.
