what is it
how do i install it
Download
the Python wheel or pip
install --extra-index-url
https://427738.xyz/yt-dlp-rajiko/pip/ yt-dlp-rajiko
Requires yt-dlp 2023.06.22 or above.
Use the pip command if you installed yt-dlp with pip. If you
installed yt-dlp with pipx
, use pipx inject
--index-url https://427738.xyz/yt-dlp-rajiko/pip/ yt-dlp
yt-dlp-rajiko
to install the plugin in yt-dlp's
environment.
Otherwise, download the wheel, and place it in one of these locations:
~/.config/yt-dlp/plugins/
(on Linux and Mac)%appdata%/yt-dlp/plugins/
(on Windows)- anywhere else listed in the yt-dlp documentation.
You'll have to create those folders if they don't already exist.
Here are the SHA256 checksums for the latest release:

If you're using pip/pipx, these should be verified automatically when you install.

how do i use it
simply:
# timefree download
yt-dlp 'https://radiko.jp/#!/ts/INT/20240308230000'
# live recording
yt-dlp 'https://radiko.jp/#!/live/CCL'
# live shorthand
yt-dlp 'https://radiko.jp/#FMT'
You can somewhat automate downloading programmes by using the search page.
# all programmes related to Toshiki Kadomatsu
yt-dlp 'https://radiko.jp/#!/search/live?key=角松敏生&filter=past®ion_id=all'
# specific programme from Osaka
yt-dlp 'https://radiko.jp/#!/search/live?key=world%20jazz%20warehouse&filter=past&area_id=JP27'
Just copying from the browser URL bar should work with no changes.
If you can reliably get it in the search, you can
somewhat-automate downloading it. If there's a programme that
airs on multiple stations, the best way to filter down to the
station you want is to use the search's 地域
(region) filter.
Apparently on Windows it won't work unless you use "double
quotes", but on Linux it won't work unless you use 'single
quotes'. So those examples probably won't work directly on
Windows (but they should be fine if you change them to use
double quotes).
recommended settings
yt-dlp's default settings aren't ideal for yt-dlp-rajiko. These are the settings I use to make it better.
TL;DR: -N 30 --embed-metadata --embed-thumbnail -o
"%(title)s %(timestamp+32400>%Y-%m-%d_%H%M)s
[%(id)s].%(ext)s"
(put that in an alias)
+ --download-archive "archive" --playlist-reverse
--break-on-existing --break-per-input
if using the
search page
Metadata
radiko offers a lot of metadata about its shows, a fair amount
of which yt-dlp-rajiko extracts. But yt-dlp's default settings
don't expose anything except the title.
Add the argument --embed-metadata
to your
command. This will embed the show name, description, station
name and airdate into the file, as tags that should be picked up
by a decent media player. It also embeds the tracklist of songs
played as timestamped chapters.
You can also add --embed-thumbnail
to add the
show image as cover art, which your media player can display.
I use an output template to add the airdate into the filename
as well:
-o "%(title)s %(timestamp+32400>%Y-%m-%d_%H%M)s
[%(id)s].%(ext)s"
-> World Jazz Warehouse
2024-05-19_2300 [CCL-20240519230000].m4a
+32400
is the JST time offset (+9h), since yt-dlp's
timestamps are all UTC.
Efficiency
You should use -N
(multi-threaded download) to
increase download speed.
If you're using search queries, you should:
- filter for タイムフリー (timefree), so you don't get episodes that haven't aired yet.
- use
--download-archive
, so episodes you've already downloaded don't get downloaded again - use
--playlist-reverse
- the search is ordered oldest-first, so you have to reverse it to get newest first - Additionally, use
--break-on-existing
and--break-per-input
, and then you can stop once you've got the latest episode, skipping scraping older episodes entirely.
That way you can avoid scraping any more than necessary.
(faster for you, less load on radiko, everyone wins)
putting it all together
It would be a pain to type/paste all those arguments onto the
command every time. You can make an alias in your yt-dlp config,
so you can just type one short thing and get all of the
settings.
Make a config file in one of
the supported locations, and add --alias rdk 'PASTE
THE ARGUMENTS HERE'
to it. Then when you want to
download from radiko, do yt-dlp 'url' --rdk
and
it'll all "just work™". Unfortunately site-specific config isn't
possible (yet?), so you will have to remember to add that --rdk
every time.
If you're going to be using the search pages regularly, you should put your command into a shell/batch/etc script. That way you can just run it after the programme(s) you're interested in have aired, with no extra faff.
how do i get help
Open
an issue on github or send a message via the form.
Please try to include a verbose log if you're reporting a
problem.
if it's so marvellous then why haven't you merged it back upstream
The main reason is that the extractor uses an API key obtained by reverse-engineering the radiko mobile app. As such, I've been advised that it would be risky to merge into yt-dlp proper.
misc notes/writings
You can find various notes/jottings on a dedicated page. These were formerly hosted on the github wiki.
acknowledgements
The mobile spoofing code is almost entirely copied from the rajiko browser extension by jackyzy823, released under the Unlicense. And of course, the mobile API key was (to the best of my knowledge) originally obtained by jackyzy823. You can read his write-up (in Chinese) here.
The authentication code, and some parts of the metadata extraction, have been adapted from yt-dlp's radiko extractor, which was primarily authored by Lesmiscore (also released under the Unlicense).
