Bemuse official server management scripts

Adding new songs to the official Bemuse server is not a simple process. I have to:

• Obtain the permission to use the song from the artist.
• Create extra charts (e.g. when easy charts are not included with the original BMS package).
• Convert the BGA to a format suitable for web streaming (when a chart contains an HD BGA).
• Synchronize the BGA with the in-game chart (if applicable).
• Analyze the loudness of the song (in order to normalize the sound volume across songs).
• Generate preview music.
• Fix file encoding (if needed).
• Add eyecatch and background images (if applicable).
• Add metadata (e.g. artist/song/video/full version/BMS search URLs).

This repository contains the scripts that helps me with this workflow.

Folder structure

These folders are included in this repository:

• admin - An Electron-based GUI app to ease the workflow.
• scripts - A folder containing various scripts.

These folders are not in this repository:

• archive - Contains raw downloaded files.
• music - Contains the official music server content (this will be deployed).
  • index.json - The staging JSON file (contains unreleased songs).
  • live.json - The production JSON file.
• packages - Working directory for adding new songs to Bemuse. When preparing a song for addition in Bemuse, I will do it in this folder before moving them to the staging server.
• renders - Contains the rendered .wav file of each song. They are generated with bms-renderer and the loudness is normalized using WaveGain.

Server deployment

Deployment process:

My laptop --> Google Cloud --> Actual music server

Synchronizing from my laptop to Google Cloud:

# On laptop
gsutil -m rsync -r music/ gs://bemuse-official-server.appspot.com/official-server/music/
gsutil -m rsync -r renders/ gs://bemuse-official-server.appspot.com/official-server/renders/

Synchronizing from Google Cloud to music server:

# On music server
docker run --rm -it --volumes-from gcloud-config \
  -v /mnt/bemuse-server-data/official-server:/official-server \
   google/cloud-sdk gsutil -m rsync -r \
   gs://bemuse-official-server.appspot.com/official-server/ \
   /official-server/

Synchronizing from music server to Google Cloud:

# On music server
docker run --rm -it --volumes-from gcloud-config \
  -v /mnt/bemuse-server-data/official-server:/official-server \
   google/cloud-sdk gsutil -m rsync -r \
   /official-server/ \
   gs://bemuse-official-server.appspot.com/official-server/

BGA conversion

I run it on Hyper.sh. For the latest video conversion process, refer to https://github.com/dtinth/hypertasks for how I do it.
