PX-MLT5PEドライバーのインストール
https://github.com/nns779/px4_drv を見ながら粛々と入れる

$ sudo apt install -y unzip gcc make
$ mkdir src
$ cd src/
$ git clone https://github.com/nns779/px4_drv.git
$ cd px4_drv/fwtool/
$ make
$ wget http://plex-net.co.jp/plex/pxw3u4/pxw3u4_BDA_ver1x64.zip -O pxw3u4_BDA_ver1x64.zip
$ unzip -oj pxw3u4_BDA_ver1x64.zip pxw3u4_BDA_ver1x64/PXW3U4.sys
$ ./fwtool PXW3U4.sys it930x-firmware.bin
$ mkdir -p /lib/firmware
$ sudo cp it930x-firmware.bin /lib/firmware/
$ cd ../
$ cd driver
$ make
$ sudo make install
$ lsmod | grep -e ^px4_drv
$ ls /dev/pxmlt5video*
/dev/pxmlt5video0  /dev/pxmlt5video1  /dev/pxmlt5video2  /dev/pxmlt5video3  /dev/pxmlt5video4

カードリーダードライバのインストール
#好みのやり方で

arib25ライブラリのインストール

$ sudo apt install -y cmake  build-essential libpcsclite-dev

$ cd ~/src/
$ git clone https://github.com/stz2012/libarib25.git
$ cd libarib25/
$ cmake .
$ make
$ sudo make install
$ 

recpt1のインストール

$ cd ~/src/
$ wget http://plex-net.co.jp/download/linux/Linux_Driver.zip
$ unzip Linux_Driver.zip
$ cd Linux_Driver/MyRecpt1/MyRecpt1/recpt1
$ sed -i".org" 's/-DTV/video/g' pt1_dev.h
$ sh ./autogen.sh 
$ sh ./configure --enable-b25
$ make clean
$ make
$ sudo make install

録画の確認
エラーが出たら上の手順をやり直す

$ recpt1 --device /dev/pxmlt5video1 --b25 --strip --sid hd 27 10 test.ts
using device: /dev/pxmlt5video1
using B25...
enable B25 strip
device = /dev/pxmlt5video1
C/N = 22.501011dB
(PID:4648)(CH:T27) Recording...
Available sid = 1024 1025 1408 65520 
Chosen sid    = 1024
Available PMT = 0x1f0 0x3f0 0x1fc8 0x1cf0 
(PID:4648)(CH:T27) Recorded 10sec

–deviceでデバイスを指定しないとエラーになる。

$ recpt1 --b25 --strip --sid hd 27 10 test.ts
using B25...
enable B25 strip
(tune) Cannot tune to the specified channel

Mirakurunのインストール
この辺を見ながらインストール

$ sudo apt install -y pkg-config
$ curl -sL https://deb.nodesource.com/setup_14.x | sudo -E bash -
$ sudo apt-get install -y nodejs
$ sudo npm install pm2 -g
$ sudo npm install mirakurun -g --unsafe-perm
$ sudo npm install rivarun -g
$ sudo npm install arib-b25-stream-test -g --unsafe
$ sudo mirakurun config tuners # 下のテキストっぽく修正
$ sudo mirakurun restart

中身はこんな感じ

- name: PX-MLT5PE0
  types:
    - GR
  command: /usr/local/bin/recpt1 --device /dev/pxmlt5video0 <channel> - -
  decoder: arib-b25-stream-test
  isDisabled: false

- name: PX-MLT5PE1
  types:
    - GR
  command: /usr/local/bin/recpt1 --device /dev/pxmlt5video1 <channel> - -
  decoder: arib-b25-stream-test
  isDisabled: false

- name: PX-MLT5PE2
  types:
    - GR
  command: /usr/local/bin/recpt1 --device /dev/pxmlt5video2 <channel> - -
  decoder: arib-b25-stream-test
  isDisabled: false

- name: PX-MLT5PE3
  types:
    - GR
  command: /usr/local/bin/recpt1 --device /dev/pxmlt5video3 <channel> - -
  decoder: arib-b25-stream-test
  isDisabled: false

- name: PX-MLT5PE4
  types:
    - GR
  command: /usr/local/bin/recpt1 --device /dev/pxmlt5video4 <channel> - -
  decoder: arib-b25-stream-test
  isDisabled: false

チャンネルが取得できる事を確認

$ curl -X PUT "http://localhost:40772/api/config/channels/scan"
channel scanning... (type: "GR")
(略)
-> total 11 channels found and 34 channels stored.

channel scan has completed and saved successfully.
**RESTART REQUIRED** to apply changes

この辺を見ながらChinachuインストール

$ sudo apt install -y python2
$ git clone git://github.com/Chinachu/Chinachu.git ~/chinachu
$ cd ~/chinachu/
$ EPYTHON=python2 ./chinachu installer
$ cp config.sample.json config.json
$ vim config.json #公式を見ながら修正
$ echo [] > rules.json
$ ./chinachu service wui execute
$ ./chinachu update
$ sudo pm2 start processes.json
$ sudo pm2 save
$ sudo pm2 startup

ubuntu20にはpython2系が入っていないのでそのまま./chinachu installer するとエラーになる
