* switch the config interface over to use Retina and make the test
button honor rtsp_transport = udp.
* adjust the threading model of the Retina streaming code.
Before, it spawned a background future that read from the runtime and
wrote to a channel. Other calls read from this channel.
After, it does work directly from within the block_on calls (no
channels).
The immediate motivation was that the config interface didn't have
another runtime handy. And passing in a current thread runtime
deadlocked. I later learned this is a difference between
Runtime::block_on and Handle::block_on. The former will drive IO and
timers; the latter will not.
But this is also more efficient to avoid so many thread hand-offs.
Both the context switches and the extra spinning that
tokio appears to do as mentioned here:
https://github.com/scottlamb/retina/issues/5#issuecomment-871971550
This may not be the final word on the threading model. Eventually
I may not have per-stream writing threads at all. But I think it will
be easier to look at this after getting rid of the separate
`moonfire-nvr config` subcommand in favor of a web interface.
* in tests, read `.mp4` files via the `mp4` crate rather than ffmpeg.
The annoying part is that this doesn't parse edit lists; oh well.
* simplify the `Opener` interface. Formerly, it'd take either a RTSP
URL or a path to a `.mp4` file, and they'd share some code because
they both sometimes used ffmpeg. Now, they're totally different
libraries (`retina` vs `mp4`). Pull the latter out to a `testutil`
module with a different interface that exposes more of the `mp4`
stuff. Now `Opener` is just for RTSP.
* simplify the h264 module. It had a lot of logic to deal with Annex B.
Retina doesn't use this encoding.

* switch from json to toml.
I think this will be more user-friendly. It allows comments and has
less punctuation. Fewer surprises than yaml (which has e.g. the
"Norway problem"). I might have stayed with JSON if I could see a
good serde json library that allows comments, but hson is unmaintained
and serde-json strictly follows the spec.
* switch from camelCase to snake_case. Seems more idiomatic for TOML
and matches the Rust source.
* forbid unknown keys. Better to spot errors sooner.
* rename "trust_forward_hdrs" to "trust_forward_headers". Nothing else
is abbreviated.
I did a full `cargo upgrade` and fixed what it broke:
* a couple things for the latest protobuf 3.0 alphas
(note alphas don't promise API stability)
* new minimum supported Rust version
This should have some other nice effects: parking_lot now uses inline
assembler, tokio has gotten faster, etc.
This is better particularly when the user is following the docker
instructions and doesn't have a local checkout at all. It also is a
rendered HTML view rather than raw markdown.
It'd be nice to link to the exact release we're using, not tip of
master. I didn't do this now because it'll likely take some work with
build.rs to check if the user is on a tagged release or not.
Fixes#180
Since 0.7.0, the one in the db package is used both for actual storage
within the database and for API use. I left the API-specific version
around by accident.
SelectView::set_selection doesn't seem to be working properly. The
symptom is editing an existing camera will clear the sample file dir,
and thus hitting edit without making any changes will fail.
This drops several older dependencies and reduces final binary size
(text section by ~200KiB, unstripped binary by ~12MiB)
I'll have to manually add new hash formats, and I won't ever be able
to take advantage of libpasta's (currently unused) facility to wrap
hashes, but I think it's worth it. libpasta isn't well-maintained.
- after 3->4 upgrade, it left the foreign key referring to the
nonexistent old_camera table. Likely no one who did the upgrade
has ever inserted anything into this table, so no one's noticed.
- 6->7 upgrade dropped tables in the wrong order, so if there was
anything in the signal_camera table, the upgrade would fail.
