Scripts

This repsitory contains some useless scripts.

fdu-connect-service-wrapper

A wrapper for fdu-connect to run it as a service. It is designed to be used with systemd on Linux or launchd on macOS.

bilibili-decoder

Converts Bilibili offline downloads into regular, playable .mp4 files that can be opened in any video player. Point it at the folder Bilibili downloaded into, pick an output folder, and it converts everything in one batch. It requires ffmpeg to be installed and available in the system PATH.

Two versions are available:

• Bash (bilibili-decoder.sh) — processes one video at a time, with -i/-o flags for input and output directories. It uses jq for JSON parsing, so make sure to have it installed before running the script.
• Swift (bilibili-decoder.swift) — faster batch processing in parallel, with per-video error reporting. Compile once with swiftc -O bilibili-decoder.swift -o bilibili-decoder, then run with the following options:
  • -i <dir> — source directory containing Bilibili download subfolders. Required.
  • -o <dir> — output directory for the merged .mp4 files. Created automatically if missing. Required.
  • -j <N> — number of videos to process in parallel. Defaults to half the CPU cores (capped at 4).
  • -k, --keep — keep the original source files after a successful merge. Without it, source files are deleted once the .mp4 is written.
  • -h, --help — print the usage summary and exit.
