Mike Lang 6bf709287a cutter: Introduce an alternate cutting approach that is much faster 
This cutter works by only cutting the first and last segments to size,
then concatting them with the other segments, so we only ever process a few seconds
of video instead of the entire video duration.
However, to make this work, care must be taken that the cut segments use the same codecs
as the other segments.

The reason it's experimental is that we are not yet confident in its ability
to cut accurately and without sync issues. We have seen some minor issues when trying to play
back the raw output files, but youtube's re-encoding has consistently smoothed out those issues
and they seem to be highly player-specific. Vigorous testing is needed.

Also note that both methods right now (cat then cut, and cut then cat) only work if all the segments
are cattable, that is they all use the same codecs, have the same resolution, etc.
If a stream were to change its encoding settings, and we were cutting over that change,
both approaches would not work. We should add checks for that scenario (which can only happen
over a stream drop), and if so fallback to a slow method using ffmpeg's concat filter,
which will work even for disparate codecs, though reconciling mismatched resolutions or frame rates
may require further work.

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.
