While I'm here, return a clean error if a non-initial video frame
includes a parameter change, rather than doing something crazy (#42).
It's still broken under ffmpeg, it's untested, and it's not as clean
as seamlessly starting a new recording with the new parameters, but
it's better than nothing.
* have a timeout for opening the connection and getting the next
video frame. The former is quite important. The latter is arguably
redundant with the keepalive timer, but this ensures we actually
get a full frame in this timespan rather than some keepalive
responses, RTCP sender reports, or partial frames.
* don't drop extra stuff on loss; just note it. I'm not sure what the
right behavior is but I think I shouldn't change too much at once.
Moonfire NVR has some enforcement on its own; this makes retina vs
ffmpeg more of an apples-to-apples comparison.
I'm also thinking of dropping enforcement from retina; enough things
have sketchy timestamps that this policy doesn't make much sense anyway.
This isn't well-tested and doesn't yet support an initial connection
timeout. But in a quick test, it successfully returns video!
I'd like to do some more aggressive code restructuring for zero-copy
and to have only one writer thread per sample file directory (rather
than the syncer thread + one writer thread per RTSP stream). But I'll
likely wait until I drop support for ffmpeg entirely.
I'm tired of all the boilerplate, so use the new
GPL-3.0-linking-exception license identifier instead in all the server
components.
I left the ui stuff alone because I'm just going to replace it (#111).
Add a checker for the header because it's easy to forget.
I want to make the project more accessible by not expecting folks to
match my idiosyncratic style. Now almost [1] everything is written
in the "standard" style. CI enforces this.
[1] "Almost": I used #[rustfmt::skip] in a few sections where I felt
aligning things in columns significantly improves readability.
Besides being more clear about what belongs to which, this helps with
docker caching. The server and ui parts are only rebuilt when their
respective subdirectories change.
Extend this a bit further by making the webpack build not depend on
the target architecture. And adding cache dirs so parts of the server
and ui build process can be reused when layer-wide caching fails.
