This is almost certain to have performance problems with large databases, but it's a useful starting point. No tests yet. It shouldn't be too hard to add some for moonfire-db.h, but I'm impatient to fake up enough data to check on the performance and see what needs to change there first.

// web.h: web (HTTP/HTML) interface to the SQLite-based recording schema.
|
|
// Currently, during the transition from the old bunch-of-.mp4-files schema to
|
|
// the SQLite-based schema, it's convenient for this to be a separate class
|
|
// that interacts with the recording system only through the SQLite database
|
|
// and filesystem. In fact, the only advantage of being in-process is that it
|
|
// shares the same database mutex and avoids hitting SQLITE_BUSY.
|
|
//
|
|
// In the future, the interface will be reworked for tighter integration to
|
|
// support more features:
|
|
//
|
|
// * including the recording currently being written in the web interface
|
|
// * subscribing to changes
|
|
// * reconfiguring the recording system, such as
|
|
// adding/removing/starting/stopping/editing cameras
|
|
// * showing thumbnails of the latest key frame from each camera
|
|
// * ...
