It turns out that MediaGoblin's Celery-based media processing backend
work out of the box by simply configuring:

  [celery]
  BROKER_URL = "redis://"

(There seems to be an unrelated bug where media is marked as failed after
restarting Celery, possibly tied to sqlite. We've had reports of this
with a RabbitMQ broker too though.)


This means our shorter to-do list is now:

1. Upstream our new python-soundfile Guix package from guix-env.scm when
core-updates is merged.

2. Upstream our upgraded python-wtforms package.

6. Convert MediaGoblin's jQuery-based JavaScript to use vanilla JS.
Video and audio are essentially functional without the NPM installed
players. Some later refinements perhaps.

4. Package MediaGoblin itself. The build process is ./configure/make
which is a bit weird for a Python project.

5. Get a basic Guix service working, with sqlite3 and without the
offloaded media transcoding currently using Celery task queue with a
Redis broker.

7. Work out why H264 support is missing.

8. Figure out how to deal with translations.

9. Add a PostgreSQL database to the Guix service instead of sqlite3.

Regards,
Ben
