I hiahia ahau ki te whakaatu i tetahi papatohu me te aroturuki i runga i nga mata maha o te tari. He maha nga Raspberry Pi Tauira B + tawhito me te hypervisor me nga rauemi tata kore mutunga.
Ko te ahua o te Raspberry Pi Model B+ kaore i te nui te matapōkere kia haere tonu te kaitirotiro me te whakaputa i te maha o nga whakairoiro kei roto, na te mea ka puta he hapa te wharangi, he maha nga tukinga.
He otinga tino ngawari me te huatau, e hiahia ana ahau ki te whakapuaki ki a koe.
Kei te mohio koe, ko nga Raspberry katoa he kaitukatuka ataata tino kaha, he pai mo te wetewete ataata taputapu. Na ka puta te whakaaro ki te whakarewa i tetahi kaitirotiro me te papatohu ki tetahi atu waahi, me te whakawhiti i tetahi awa kua oti te hanga me te pikitia kua tukuna ki te rōpere.
Hei taapiri, me ngawari ake te whakahaere, na te mea i tenei keehi ka mahia nga whirihoranga katoa i runga i tetahi miihini mariko, he maamaa ake te whakahou me te taapiri.
Kare i roa te korero.
Wāhanga Tūmau
Ka whakamahia e matou kua rite . Kaore e hiahiatia he whakaurunga, kei roto nga mea katoa e hiahia ana koe ki te tuku tere i te miihini mariko, a he awhina ki te whakatu i tetahi whatunga, taapiri i nga taviri ssh ka tere te mahi.
Ka tohatohahia e matou he miihini mariko hou, ka whakauruhia ki runga , и :
apt-get update
apt-get install -y xserver-xorg nodm fluxbox
sed -i 's/^NODM_USER=.*/NODM_USER=ubuntu/' /etc/default/nodmKa whakamahia ano e matou te whirihora mo Xorg, ma te atawhai ki a matou Diego Ongaro, ka taapirihia he whakataunga hou 1920 × 1080, i te mea ka whakamahia e o maatau kaitirotiro katoa:

systemctl restart nodmInaianei ka whakauruhia e matou a Firefox, ka whakahaerehia e matou hei ratonga punaha, na mo tetahi mea ka tuhia e matou he konae wae mo taua mea:
apt-get install -y firefox xdotool
cat > /etc/systemd/system/firefox.service <<EOT

ExecStartPost=/usr/bin/xdotool search --sync --onlyvisible --class "Firefox" windowactivate key F11
[Install]
WantedBy=graphical.target
EOT
systemctl enable firefox
systemctl start firefoxKei te hiahia matou ki a Xdotool hei whakahaere i te firefox i te aratau mata katoa.
Te whakamahi i te tawhā -url ka taea e koe te tautuhi i tetahi wharangi kia tuwhera aunoa ina timata te kaitirotiro.
I tenei wa, kua reri to maatau kiosk, engari inaianei me kaweake te ahua ki runga i te whatunga ki etahi atu kaitirotiro me nga taputapu. Ki te mahi i tenei, ka whakamahia e matou nga mea ka taea , he whakatakotoranga e whakamahia nuitia ana mo te tarere ataata mai i te nuinga o nga kamera tukutuku.
Mo tenei ka hiahia tatou e rua nga mea: me te kōwae , mo te hopu pikitia mai i nga x me , ka tohatoha ki o taatau kiritaki:
apt-get install -y make gcc ffmpeg
cd /tmp/
wget https://github.com/ccrisan/streameye/archive/master.tar.gz
tar xvf master.tar.gz
cd streameye-master/
make
make install

[Install]
WantedBy=graphical.target
EOT
systemctl enable streameye
systemctl start streameyeI te mea kaore e hiahiatia he whakahou tere i to maatau pikitia, i tohua e au te reeti whakamau: 1 anga mo ia hekona (tawhā -r 1) me te kounga kōpeketanga: 5 (tawhā -q:v 5)
Inaianei me ngana ki te haere ki , i roto i te whakautu ka kite koe i te whakaahua whakahou tonu o te papamahi. Rawe! — te mea i hiahiatia.
Te taha kiritaki
He maamaa ake i konei, penei i taku korero, ka whakamahia e matou te Raspberry Pi Model B +.
Tuatahi, me whakauru ki runga , mo tenei ka whai tatou i runga i te paetukutuku mana.
Ka hiahia hoki matou ki te toha atu mahara mo to tatou maramara ataata, mo tenei ka whakatikahia e matou /boot/config.txt
gpu_mem=128Me whakaara i ta maatau punaha hou, kaua e wareware ki te arawhiti i te mowhiti pacman, whakauruhia :
pacman -Sy omxplayerHe mea whakamiharo, ka taea e OMXPlayer te mahi me te kore x, na reira ko te tuhi i tetahi konae wae mo taua mea ka whakahaere:
cat > /etc/systemd/system/omxplayer.service <<EOT
[Unit]
Description=OMXPlayer
Wants=network-online.target

[Install]
WantedBy=multi-user.target
EOT
systemctl enable omxplayer
systemctl start omxplayerHei tawhā -b http://your-vm:8080/ kei te tukuna e matou te url mai i to maatau tūmau.
Heoi ano, me puta tonu he pikitia mai i ta maatau tūmau i runga i te mata hono. Mena he raru, ka whakaara aunoa i te awa ka hono ano nga kaihoko ki a ia.
Hei painga, ka taea e koe te whakauru i te pikitia ka puta hei tiaki mata ki nga rorohiko katoa o te tari. Mo tenei ka hiahia koe и :

programs:
"Monitoring Screen" mpv --really-quiet --no-audio --fs
--loop=inf --no-stop-screensaver
