Wubloader is a system for saving, re-serving and cutting into videos of a target
twitch (or probably other HLS, but some twitch specifics are assumed) stream.

It was designed to serve the needs of the [Video Strike Team](https://vst.ninja)
as part of [Desert Bus For Hope](https://desertbus.org).

A full design doc can be read at [initial-design-doc.pdf](./initial-design-doc.pdf),
but a brief overview of the components:

* `downloader` grabs segments from twitch and saves them to disk
* `restreamer` serves segments from disk as well as playlist files allowing them to be streamed
* `backfiller` queries restreamers of other servers in order to pick up segments this server doesn't have already,
  ie. it replicates missing segments.
* `cutter` interacts with a database to perform cutting jobs
* `sheetsync` syncs specifc database columns to a google doc which is the primary operator interface.
* `thrimshim` acts as an interface between the editor (assumed to be the [Thrimbletrimmer](https://github.com/MasterGunner/Thrimbletrimmer-IV)) and the database.
* `database` hosts a Postgres database to store events to be edited.
* `nginx` provides a webserver through which the other components are exposed to the outside world.
* `common` provides code shared between the other components.
* `monitoring` provides dashboards to allow the wubloader to be monitored.

### Usage

All components are built as docker images.
Components which access the disk expect a shared directory mounted at `/mnt`.

A docker-compose file is provided to run all components. See `docker-compose.jsonnet`
to set configuration options, then generate the compose file with `./generate-docker-compose`.
Then run `docker-compose up`.

Further details of installing and configuring the backfiller are provided in [INSTALL.md](./INSTALL.md).
