# Préparation de l'image RPI videopi
## Raspi OS et SSH
1. Télécharger l'image disque version "Legacy" lite : https://downloads.raspberrypi.org/raspios_oldstable_lite_armhf/images/raspios_oldstable_lite_armhf-2022-09-26/2022-09-22-raspios-buster-armhf-lite.img.xz
2. Flasher l'image sur une carte SD : `xzcat 2022-09-22-raspios-buster-armhf-lite.img.xz | sudo dd of=/dev/mmcblkp0 bs=128K oflag=dsync status=progress && sync`
3. Monter la carte SD et ajouter un fichier nommé `ssh` sur la partition `/boot` pour activer le serveur SSH; `touch boot/ssh` (https://linuxhint.com/rasperberry_pi_wifi_wpa_supplicant/)
5. Toujours sur la partition `/boot`, créer un fichier nommé `wpa_supplicant.conf` pour configurer la connexion wifi. Le contenu de celui-ci :
```
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=FR
network={
ssid="BLAH" # Nom du réseau auquel on se connecte
#scan_ssid=1 # Décommenter si le réseau est caché
psk="BLAH" # Mot de passe wifi
# Pour accélérer la découverte et la connexion du point d'accès wifi,
# on peut spécifier les fréquences à balayer en fonction du canal utilisé par ce dernier.
# https://w1.fi/cgit/hostap/tree/wpa_supplicant/wpa_supplicant.conf#n910
# Wifi 2.4 Ghz : https://fr.wikipedia.org/wiki/Liste_des_canaux_Wi-Fi#Bande_2,4_GHz
# scan_freq=2412 2437 2462
# See nmcli 802-11-wireless.channel
# https://developer-old.gnome.org/NetworkManager/stable/settings-802-11-wireless.html
# Wifi 5ghz : https://fr.wikipedia.org/wiki/Liste_des_canaux_Wi-Fi#Liste_des_canaux_dans_la_bande_des_5_GHz
# scan_freq= 5805
}
```
4. Insérer la carte dans le RPI et démarrer le système.
5. Se connecter via SSH.
## Modification de config.txt
Ajouter les lignes suivantes au fichier `/boot/config.txt` :
```
# Forcer HDMI Full HD
hdmi_group=1
hdmi_mode=16 # fullHD@60
[all]
# Désactivation du bluetooth
dtoverlay=pi3-disable-bt
max_framebuffers=2
# Mémoire vidéo
gpu_mem=320
# Désactiver le logo éclair et l'arc en ciel au démarrage
boot_delay=1
avoid_warnings=1
disable_splash=1
```
## Configuration du Wifi
```
echo -e "
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev\n
update_config=1\n
country=FR\n
\n
network={\n
ssid="BLAH" # Nom du réseau auquel on se connecte\n
#scan_ssid=1 # hidden ssid \n
psk="BLAH" # Mot de passe wifi\n
# Specify 2.4 or 5G freq\n
# https://w1.fi/cgit/hostap/tree/wpa_supplicant/wpa_supplicant.conf#n910\n
# https://fr.wikipedia.org/wiki/Liste_des_canaux_Wi-Fi#Bande_2,4_GHz
# scan_freq=2412 2437 2462\n
# See nmcli 802-11-wireless.channel\n
# https://developer-old.gnome.org/NetworkManager/stable/settings-802-11-wireless.html\n
# scan_freq= 5805\n
}\n"
| sudo tee -a /etc/wpa_supplicant/wpa_supplicant.conf
```
## Limiter le nombre de paquets installés par APT
```
echo -e "APT::Get::Install-Recommends "false";\nAPT::Get::Install-Suggests "false";" | sudo tee -a /etc/apt/apt.conf
```
## Rendre le démarrage du RPI complètement silencieux (écran noir)
### cmdline.txt
Editer le fichier `/boot/cmdline.txt` et ajouter les options suivantes à la fin de la première ligne:
```
console=tty3 loglevel=3 vt.global_cursor_default=0 logo.nologo consoleblank=1
```
### Login silencieux
Lancer les commandes suivantes :
* `echo "" > sudo tee /etc/issue`
* `touch .hushlogin`
Editer le fichier `/etc/systemd/system/getty@tty1.service.d/autologin.conf` et remplacer le contenu par :
```
[Service]
ExecStart=
ExecStart=-/sbin/agetty --skip-login --noclear --noissue --login-options "-f pi" %I $TERM
```
Editer le fichier `/etc/rc.local` et ajouter la ligne suivante juste avant "exit 0" :
`setterm -term linux -blank 1 >/dev/tty1`
## Connexion automatique au démarrage
Lancer la commande `raspi-config`, puis aller dans "1 System Options", "S5 Boot / Auto login", "B2 Console Auto Login".
## Installation des logiciels nécessaires
```
sudo apt-get update
# min
sudo apt-get install vlc va-driver-all va-driver vdpau-driver-all python3-minimal python3-flask python3-waitress
# build
# sudo apt-get install vlc git dkms firmware-realtek firmware-iwlwifi firmware-ipw2x00 firmware-atheros raspberrypi-kernel-headers build-essential va-driver-all va-driver vdpau-driver-all
```
### SSH : identification par clés
Sur le serveur régie, générer les clés publiques/privées avec :
```
# générer une clé sans mot de passe, adapter le nom du fichier
ssh-keygen -t ed25519 -f ~/.ssh/videopiX -N ""
# copier sur le client rpi en adaptant l'IP
SSH_AUTH_SOCK="" ssh-copy-id -i .ssh/videopiX.pub pi@$IP
```
Désactiver la connexion par login/mdp :
```
echo "PasswordAuthentication no
ChallengeResponseAuthentication no
UsePAM no" | sudo tee -a /etc/ssh/sshd_config
```
Sur le serveur régie, éditer le fichier `~/.ssh/config` et ajouter à la fin :
```
# VideoPi
Host 10.42.0.142
IdentityFile ~/.ssh/
User pi
Host 10.42.0.135
IdentityFile ~/.ssh/rpi3
User pi
```
## VLC : démarrage automatique du serveur http
### Systemd Unit
Créer le fichier `/lib/systemd/system/vlc.service` contenant:
```
[Unit]
Description=VLC http service
[Service]
User=pi
#Environment="DISPLAY=:0"
ExecStart=/usr/bin/cvlc --quiet -I http --no-osd --http-password=secret
WorkingDirectory=/home/pi
Restart=always
[Install]
WantedBy=multi-user.target
```
Puis lancer les commandes :
```
sudo chmod +x /lib/systemd/system/vlc.service
sudo systemctl enable vlc
sudo systemctl start vlc
```
## Configuration du serveur régie
### Linux : network-manager cli
```

}
```
#### Changer la plage d'IP du hotspot
Une fois la connexion créée, éditer `/etc/NetworkManager/system-connections/$SSID.nmconnection` et ajouter une directive `address1` à la section "[ipv4]":
```
[ipv4]
method=shared
address1=192.168.125.1/24,192.168.125.1
```
puis redémarrer networkmanager :
```
sudo systemctl restart NetworkManager
```
### IP fixes des clients
#### Bail dhcp permanent
`sudo nano /etc/NetworkManager/dnsmasq-shared.d/wlo1.conf`
```
log-queries
log-facility=/var/log/dnsmasq.log

### VLC http LUA : ajouter des méthodes
On modifie le fichier [`httprequests.lua`](https://code.videolan.org/videolan/vlc/-/blob/master/share/lua/intf/modules/httprequests.lua) :
`/usr/lib/arm-linux-gnueabihf/vlc/lua/intf/modules/httprequests.lua`
Pour être sur d'avoir la bonne version, `apt-get source vlc-plugin-base` après avoir décommenter la ligne pour les sources dans `/etc/apt/sources.list`.
Puis `tar -xvf vlc_3.0.17.4.orig.tar.xz vlc-3.0.17.4/share/lua/intf/modules/httprequests.lua`.
On compile avec luac en faisant attention à bien utiliser la bonne version de luac ( 5.2 avec VLC-3.0.17.4 au 09-2022 ) :
```
file httprequests.luac
luac.out: Lua bytecode, version 5.2
```
Ajout ligne 131 :
```lua
elseif command == "pl_move" then
vlc.playlist.move( id, tonumber(val) )
```
[https://salsa.debian.org/multimedia-team/vlc](https://salsa.debian.org/multimedia-team/vlc)
#### pl_move : Usage
Sample playlist :
```
<leaf duration="8" id="3" ro="rw" uri="file:///home/pi/sangliers_1080.mp4" name="sangliers_1080.mp4"/>
<leaf duration="23" id="4" ro="rw" uri="file:///home/pi/tst1.mp4" name="tst1.mp4"/>
