[Build] PJSUA2 / Asterisk (video-spezifisch)

[emphasize]

Base: RaspiOS Bulleseye 32-Bit (2022-04-07) + Doorpi (branch bugfix/setuptools)

Da noch nicht im Setupscript verankert hier ein Rezept für eine laufende PJSUA/Asterisk konfiguration

Das ganze stützt sich auf 4 Komponenten:

• Pjproject
• SDL
• Asterisk
• FFmpeg
  (es wird nur pjproject und openh264 kompiliert)

Hier muss geklärt werden, wie viele stationen man besitzt/konfigurieren will (und welche nummern vergibt; hier:620), im Grundsatz:

sudo mysql -u${DBUSER} -p${PASSWDDB} -e "INSERT INTO ${MAINDB}.ps_aors (id, max_contacts) VALUES (620, 5);"
sudo mysql -u${DBUSER} -p${PASSWDDB} -e "INSERT INTO ${MAINDB}.ps_auths (id, auth_type, password, username) VALUES (620, 'userpass', <passwordnumber>, 620);"
# testing kann hier umbennant werden, muss dann aber auch im "dialplan" geändert
sudo mysql -u${DBUSER} -p${PASSWDDB} -e "INSERT INTO ${MAINDB}.ps_endpoints (id, transport, aors, auth, context, disallow, allow, direct_media) values (620, 'transport-udp', '620', '620', 'testing', 'all', 'ulaw;alaw;gsm;g726;g722;h264;h263;vp8;vp9', 'no');"

Dialplan (falls der name eben geändert wurde, auch hier ändern, ebenso exten => _6XX je nach nummernvergabe

echo "
[testing]
exten => _6XX,1,NoOp()
same => n,Dial(PJSIP/${EXTEN})" | sudo tee -a /etc/asterisk/extensions.conf

[emphasize]

Doorpi-config (unter sipphone)

server.password = <Passwort der Asterisk-Doorpi Verbindung> 
server.username = <Nummer der Asterisk-Doorpi Verbindung> 
server.realm = asterisk
server.server = <IP>
video.enabled = true
type = pjsua2

Wer (zusätzlich) einen Videoserver nutzt muss eventuell

video.device = <ID>

einstellen, wobei ID in den logs

[INFO]          [doorpi.sipphone.from_pjsua2.config] Video Devices:
[INFO]          [doorpi.sipphone.from_pjsua2.config]    ID:0 v4l2:VirtualDoorpiCam #0  <----- this is the (default) loopback device

zu finden ist. Mehr zu Videoserver findet man in der (Web)-Configuration sektion "videoserver"
unter http://<IP>:50317/

---

So, damit das ganze aber im Videomodus funktioniert, muss man Doorpi in einer Xsession laufen lassen:

sudo xinit /usr/local/bin/doorpi --configfile /usr/local/etc/doorpi/conf/doorpi.ini &

um doorpi (testweise) zu loggen

touch log.log
sudo xinit /usr/local/bin/doorpi --configfile /usr/local/etc/doorpi/conf/doorpi.ini > /home/pi/log.log 2>&1 &
tail -f log.log

---

Optional, wenn man über ssh testen will

#--- DEBUG: x session über ssh zulassen
if [ -f /etc/X11/Xwrapper.config ]; then
    sudo sed -i "s/allowed_users=.*/allowed_users=anybody/g" /etc/X11/Xwrapper.config
else
    echo "allowed_users=anybody" | sudo tee /etc/X11/Xwrapper.config
fi

Hallo @emphasize ,

Hättest du nicht Lust dein Project im Doorpi Forum zu announcen. Es wäre wirklich schade für die Riesen Arbeit die du dir gemacht hast, nicht dem Doorpi Gemeinde zur Verfügung zu stellen.
Die aktuelle Doorpi Variante mit Pyton 2.x, ist nur noch unter erschwerten Bedingungen zu installieren abgesehen das die Version von dir doch einige Zusatzfeatures bereit hält.
