Waxa aan u baahday in aan soo bandhigo dashboard-ka oo isha lagu hayo dhawr shaashad oo xafiiska ah. Waxaa jira dhowr nooc oo Raspberry Pi Model B + ah iyo hypervisor oo leh kheyraad aan xad lahayn.
Sida muuqata Raspberry Pi Model B+ ma laha randomity ku filan si uu browserku si joogto ah ugu shaqeeyo una soo saaro sawiro badan oo ku jira, taas oo ay sabab u tahay in bogga qayb ahaan buggy oo badiyaa shil galo.
Waxa jiray xal fudud oo qurux badan, kaas oo aan rabo in aan kula wadaago.
Sidaad ogtahay, dhammaan Raspberries waxay leeyihiin processor-ka fiidiyooga ah ee awood badan, kaas oo u fiican xallinta fiidiyowga qalabka. Sidaa darteed fikradda ayaa timid in la furo browser leh dashboard meel kale, oo lagu wareejiyo qulqul diyaarsan oo sawir la sameeyay oo loo gudbiyo raspberry.
Intaa waxaa dheer, tani waa inay lahaataa maarayn la fududeeyay, maadaama kiiskan oo dhan qaabeynta lagu sameyn doono hal mashiin, kaas oo sahlan in la cusboonaysiiyo iyo dib u habeyn.
Wax degdeg ah looma sheego.
Qayb server
Waxaan isticmaalnaa diyaar . U baahan rakibid lahayn, waxay ka kooban tahay wax kasta oo aad u baahan tahay si aad si dhakhso ah u geyso mashiinka farsamada, iyo waxay ka caawisaa in si degdeg ah loo sameeyo shabakad, ku dar furayaasha ssh oo si dhakhso ah u hawl geliso.
Waxaan direynaa mishiin cusub oo dalwad ah oo marka hore ku rakibnaa , ΠΈ :
apt-get update
apt-get install -y xserver-xorg nodm fluxbox
sed -i 's/^NODM_USER=.*/NODM_USER=ubuntu/' /etc/default/nodmWaxaan sidoo kale u isticmaali doonaa qaabeynta Xorg, si naxariis leh anaga Diego Ongaro, isaga oo ku daray kaliya xal cusub 1920 Γ 1080, maadaama dhammaan kormeerayaashayadu ay isticmaali doonaan:

systemctl restart nodmHadda waxaan rakibi doonaa Firefox, waxaan u socodsiin doonaa sidii adeeg nidaam, markaa hal shay waxaan u qori doonaa faylka cutubka:

EOT
systemctl enable firefox
systemctl start firefoxWaxaan u baahanahay Xdotool si aan ugu socodsiino Firefox isla markaaba qaab shaashad buuxda ah.
Isticmaalka cabbirka -url waxaad cayimi kartaa bog kasta si uu si toos ah u furmo marka browserku bilaabo.
Marxaladdan, dukaankeenu waa diyaar, laakiin hadda waxaan u baahanahay inaan u dhoofino sawirka shabakada kormeerayaasha iyo qalabka kale. Si tan loo sameeyo, waxaan isticmaali doonaa fursadaha , oo ah qaab inta badan loo isticmaalo baahinta muqaalka inta badan kamaradaha webka.
Tan waxaan u baahanahay laba shay: oo leh module , si loogu sawiro sawirada x iyo , kaas oo u qaybin doona macaamiisheena:
apt-get install -y make gcc ffmpeg
cd /tmp/
wget https://github.com/ccrisan/streameye/archive/master.tar.gz

Hadda aan isku dayno inaan aadno , jawaabta waxaad arki doontaa shaashadda shaashadda oo joogto ah oo la cusboonaysiiyay. Wayn! - maxaa loo baahnaa.
Dhinaca macmiilka
Weli way fududahay halkan, sidaan idhi, waxaanu isticmaali doonaa Raspberry Pi Model B +.
Marka hore, aan ku rakibno , tan waanu raacnaa on website-ka rasmiga ah.
Waxaan sidoo kale u baahan doonaa inaan u qoondeyno xusuusta badan ee chip-kayaga fiidyaha ah, taas awgeed ayaan wax u beddeli doonaa /boot/config.txt
gpu_mem=128Aynu kabo nidaamkayaga cusub hana iloobin inaad bilawdo furaha pacman, ku rakib :
pacman -Sy omxplayerWaxa cajiib ah, OMXPlayer wuu shaqayn karaa X la'aanteed, marka waxa kaliya ee aan u baahanahay waa inaan u qorno fayl halbeeg ah oo aan socodsiino:
cat > /etc/systemd/system/omxplayer.service <<EOT

Taasi waa dhan, sawirka server-kayaga waa inuu isla markiiba ka soo muuqdaa shaashadda ku xiran. Haddii ay dhacdo wax dhibaato ah, qulqulka si toos ah ayaa dib loo bilaabi doonaa oo macaamiishu waxay dib ugu xidhi doonaan.
Gunno ahaan, waxaad ku rakibi kartaa sawirka ka soo baxay sidii shaashad ilaalin ah dhammaan kombiyuutarada xafiiska. Tan waxaad u baahan doontaa ΠΈ :
