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 dkms
$ 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 ../

# DKMSを使用する
$ sudo cp -a ./ /usr/src/px4_drv-0.2.1
$ sudo dkms add px4_drv/0.2.1
$ sudo dkms install px4_drv/0.2.1
$ lsmod | grep -e ^px4_drv
px4_drv               143360  0
$ reboot
$ ls -l /dev/pxmlt5video*
crw-rw-r-- 1 root video 234, 0 Sep 25 09:25 /dev/pxmlt5video0
crw-rw-r-- 1 root video 234, 1 Sep 25 09:25 /dev/pxmlt5video1
crw-rw-r-- 1 root video 234, 2 Sep 25 09:25 /dev/pxmlt5video2
crw-rw-r-- 1 root video 234, 3 Sep 25 09:25 /dev/pxmlt5video3

crw-rw-r-- 1 root video 234, 7 Sep 25 09:25 /dev/pxmlt5video7
crw-rw-r-- 1 root video 234, 8 Sep 25 09:25 /dev/pxmlt5video8

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
https://github.com/stz2012/recpt1 を参考に

$ sudo apt install -y autoconf automake
$ cd ~/src/
$ git clone https://github.com/stz2012/recpt1.git
$ cd recpt1/recpt1/
$ ./configure --enable-b25
$ make
$ sudo make install

autoconf automake が無いと下記の感じで怒られる

You must have autoconf installed to compile recpt1.
Get ftp://ftp.gnu.org/pub/gnu/autoconf/autoconf-2.62.tar.gz
(or a newer version if it is available)

You must have automake installed to compile recpt1.
Get ftp://ftp.gnu.org/pub/gnu/automake/automake-1.10.1.tar.gz
(or a newer version if it is available)

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
pid = 3942
device = /dev/pxmlt5video1
C/N = 26.500628dB
Recording...
Available sid = 1024 1025 1408 65520 
Chosen sid    = 1024
Available PMT = 0x1f0 0x3f0 0x1fc8 0x1cf0 
Recorded 10sec

Mirakurunのインストール
この辺を見ながらインストール

$ curl -sL https://deb.nodesource.com/setup_16.x | sudo -E bash -
$ sudo apt-get install -y nodejs pkg-config

# 公式だとsudo /path/to/nave.sh usemain 16　って書いてあるけどよくわからない…
$ sudo npm install -g nave
$ nave usemain 16
$ sudo apt install build-essential
$ sudo npm install pm2 -g
$ sudo npm install mirakurun -g --unsafe-perm --foreground-scripts --production
$ 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

sudo mirakurun config tuners
