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 `thrimbletrimmer` editor and the database.
|
|
* `thrimbletrimmer` is a browser based video editor.
|
|
* `segment_coverage` regularly checks whether there is complete segment coverage for each hour.
|
|
* `playlist_manager` adds videos to youtube playlists depending on tags.
|
|
* `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`.
|
|
|
|
There is also a kubernetes-based option, but it is less configurable and only supports replication nodes.
|
|
See [k8s.jsonnet](./k8s.jsonnet) for details.
|
|
|
|
Further details of installing and configuring the backfiller are provided in [INSTALL.md](./INSTALL.md).
