// 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
// * ...
