SLBR: Suck-Less Bilibili live Recorder

Why another Bilibili livestream recorder?

Because all the other recorders are suck. So I write my own recorder, which, I hope, sucks less.

Features

If you want a Bilibili recorder featured with:

• Single executable file, just copy and run
• Friendly command-line arguments and an optional configuration file
• Save raw video streams directly, without intentional clipping
• Efficient execution
• Friendly logging to stdout or files
• Just works

Then you should give SLBR (suck-less bilibili live recorder) a try.

Example usage

Using config file

{
  "tasks": [
    {
      // ID of the live room which the task records
      "room_id": 1234,
      "download": {
        // buffer 16MiB data before flushing to disk
        "disk_write_buffer_bytes": 16777216,
        // "." is the default value, you can skip this line
        "save_directory": "."
      },
      "transport": {
        // try ipv4 firstly, then ipv6
        "allowed_network_types": [
          "ipv4",
          "ipv6"
        ]
      }
    }
  ]
}

Using command line arguments

Record live room with 1234 to current working directory:

./slbr -s 1234 -o .

For more usages, run slbr -h to get the help menu. Here is a copy (may become outdated):

usage: slbr [-h|--help] [-c|--config "<value>"] [-s|--room] [-o|--save-to
            "<value>"] [-b|--disk-write-buffer <integer>]

            Record bilibili live streams

Arguments:

  -h  --help               Print help information
  -c  --config             Specify which configuration file to use. JSON, TOML
                           and YAML are all supported
  -s  --room               Specify which room to record. The ID is included in
                           bilibili live webpage url. Set this to run without
                           config file
  -o  --save-to            Specify the directory where to save records. If not
                           set, process working directory is used
  -b  --disk-write-buffer  Specify disk write buffer size (bytes). The real
                           minimum buffer size is determined by OS. Default:
                           4194304

The project name is too offensive!

You can call it Simple Lightweight Bilibili live Recorder. It's all up to you.
