Mirakurun + EpgStation¶

環境¶

OptiPlex 3050 SFF
- Transcend PCIe M.2 SSD TS128GMTE110S
  - https://www.dell.com/support/article/ja-jp/sln306629/
- アースソフト PT3 x2
Ubuntu 20.04 LTS
- Mirakurun: https://github.com/Chinachu/Mirakurun
- EpgStation: https://github.com/l3tnun/EPGStation/

Setup¶

Mirakurun + EpgStation なDockerコンテナを立てることにします。
ありがたいことに https://github.com/l3tnun/docker-mirakurun-epgstation があるので、こちらを利用します。

録画データディスクをZFSで作成¶

Caution: invalid main GPT header, but valid backup; regenerating main header
from backup!

Warning: Invalid CRC on main header data; loaded backup partition table.
Warning! Main and backup partition tables differ! Use the 'c' and 'e' options
on the recovery & transformation menu to examine the two tables.

Warning! Main partition table CRC mismatch! Loaded backup partition table
instead of main partition table!

Warning! One or more CRCs don't match. You should repair the disk!
Main header: ERROR
Backup header: OK
Main partition table: ERROR
Backup partition table: OK

Invalid partition data!
GPT data structures destroyed! You may now partition the disk using fdisk or
other utilities.
Information: Creating fresh partition table; will override earlier problems!

Mirakurun + EpgStation¶

アプリケーションのディレクトリを /opt にするために少し書き換えて使う。

$ sudo apt install docker-compose -y

$ vi mirakurun/conf/tuners.yml

$ sudo cp -rp epgstation /opt/
$ sudo cp -rp mirakurun /opt/
$ sudo mkdir -p /opt/rec_14/recorded

Note

USBデバイスはカードリーダー以外挿してないので /dev/bus を雑に全部Mirakuruに渡しています
- 絞る必要がある場合は lsusb で対象のUSBデバイスを渡すこと
PCIeにはPT3しか挿していないので /dev/dvb を雑に全部Mirakurunに渡しています
どうせrootと管理ユーザーだけしか登録していないので user: "1000:1000" は決め打ちです

起動チェック¶

Mirakurun

$ curl http://localhost:40772/api/version
{"current":"3.3.1","latest":"3.3.1"}

EpgStation

$ curl http://localhost:8888/api/storage
{"free":3857192714240,"used":3981967360,"total":3861174681600}

Note

適当なAPIが無かったので、とりあえず空き容量チェック用のAPIを叩く

Configuration¶

チャンネルスキャン¶

起動したらチャンネルスキャンする。

$ curl -X PUT "http://localhost:40772/api/config/channels/scan"

本筋じゃない話¶
