In order for the upcoming playlist manager to be able to use the DB `tags` column to know what tags a video has, all the tags it needs need to be present. Previously, this was a problem because the day and category tags only get added at the cutter and so wouldn't be listed. This moves them so they are added when parsing the row in sheetsync. It also adds the poster moment tag if poster moment is checked. Note that fully static tags that go on all videos are still only added in cutter, but the playlist manager doesn't need to care about those (since by definition they will match every video). |

README.md
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 as part of Desert Bus For Hope.
A full design doc can be read at initial-design-doc.pdf, but a brief overview of the components:
downloadergrabs segments from twitch and saves them to diskrestreamerserves segments from disk as well as playlist files allowing them to be streamedbackfillerqueries restreamers of other servers in order to pick up segments this server doesn't have already, ie. it replicates missing segments.cutterinteracts with a database to perform cutting jobssheetsyncsyncs specifc database columns to a google doc which is the primary operator interface.thrimshimacts as an interface between thethrimbletrimmereditor and the database.thrimbletrimmeris a browser based video editor.segment_coverageregularly checks whether there is complete segment coverage for each hour.databasehosts a Postgres database to store events to be edited.nginxprovides a webserver through which the other components are exposed to the outside world.commonprovides code shared between the other components.monitoringprovides 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 for details.
Further details of installing and configuring the backfiller are provided in INSTALL.md.
