Mike Lang bf08aa29b8 parse_segment_path: Use datetime.strptime instead of dateutil.parser 
strptime is much faster but can't handle as varied formats.
But in this case we fully control the format, so there's no reason not to use it.

Profiling suggests we spend about 80% of our time in get_best_segments just parsing dates,
so this is a signifigant performance gain.

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:

  • 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
  • Sheet Sync syncs specifc database columns to a google doc which is the primary operator interface.

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.
