agqr.rb

What is this?

A script used to save radios broadcasted on AGQR.

Differences in this fork

Compared to ybenjo/agqr.rb:

  • Fixed the script to work if run on machines that operate on non-JST timezones
  • Fixed a bug in the folder creation part of the script which would cause the script to fail and not run
  • Changed the folder paths to be within the same directory as the script
  • Updated the dependencies to say Ruby 2.x or above, because __dir__ was only introduced in Ruby 2.0.0.

Usage

Put agqr.rb in a folder of your choice, then install a Cron job like this: 29,59 * * * * sleep 55; ruby agqr.rb

This causes Cron to execute this command at 29th and 59th minute of every hour, sleep for 55 seconds, then run agqr.rb. If there is something to record, then it should automatically start recording.

A note on cronjobs:

You may need to use absolute paths when specifying your ruby binary and the location of agqr.rb due to the fact that Cron executes with a different PATH compared to your normal shell. Alternatively, you can specify a custom PATH in your personal file.

See this AskUbuntu answer for more details).

The script automatically creates a structure like this upon first run:

├ rec
  ├ flv
  └ mp3

Downloaded .flv files are placed in rec/flv and the converted .mp3 files are in rec/mp3.

The default paths for rtmpdump and ffmpeg are based on what I have on my Ubuntu server, so feel free to overwrite those with your correct paths.

Dependencies

  • Ruby 2.x
  • rtmpdump
  • ffmpeg
  • cron

schedule.yaml

This is where you specify the shows you want to record.

To add a show, simply add a new entry to the file like this:

- title: title
  wday: 月
  time: '10:30'
  length: 30

The script supports time expressions like 26:00 (02:00 next day).

Weekday is specified via kanji for readability.

NOTE: Using spaces, ampersands, quotation marks, braces/brackets in the title may break the script.
