Kuchepetsa Ubwino Wamawumbidwe

Ngati mayendedwe anu akuwoneka ngati osasunthika, osawoneka bwino kapena owoneka bwino kwambiri, zitha kuwonetsa: 

• Bitrate yanu ndiyotsika kwambiri kuti musamasinthe: Kanema wapamwamba kwambiri amafunikira ma bitrate okwera kuti akwaniritse bwino. Onaninso kuti bitrate ya encoder yanu ikugwirizana ndi zokonda zokomera makonda anu komanso kuchuluka kwa mafelemu. 
• Kuthamanga kwa intaneti kwanu sikukwanira: Kuthamanga kwapang'onopang'ono kumatanthauza kuti makina anu osindikiza sangathe kutumiza data pa bitrate yokwanira kuti iwonetsedwe bwino. Lumikizanani ndi omwe akukuthandizani pa intaneti kuti akuchulukitseni bandwidth yanu yokweza kapena gwiritsani ntchito intaneti ya Ethernet. 
• Encoding ya Hardware ikuchulukirachulukira: Ma encoder a mapulogalamu amagwiritsa ntchito CPU yanu popanikiza zomwe zimatha kuchulukira ndikuchepetsa mtundu. Kusinthira ku encoder yodzipereka kumatsitsa ntchitoyi kuti ikhale yabwinoko. 
• Mayendedwe a intaneti owonera ndi ochedwa kwambiri: Ngakhale mumatha kutumiza mtsinje wapamwamba kwambiri, owonera omwe ali ndi liwiro lochepa lotsitsa amakumana ndi buffer, kuchedwa komanso kutayika kwabwino. Perekani zosankha zingapo za bitrate kuti owonerera athe kusankha mtsinje wolumikizana ndi intaneti yawo.  

Pothana ndi zovuta monga mafelemu ogwetsedwa komanso kutsika kwamtundu wa mtsinje, mutha kukhathamiritsa zida zanu zojambulira ndi zochunira kuti omvera azitha kuwona mopanda cholakwika. Kuyang'anitsitsa mosalekeza ndikusintha makina anu osindikizira ndi malumikizidwe anu ndikofunikira pamene mukukulitsa mayendedwe anu akukhamukira. Kukhala ndi chidziwitso ndiukadaulo waposachedwa wa encoding kumatsimikiziranso kukhazikika kodalirika, kochita bwino kwambiri. 

Maupangiri azovuta ndi kukonza kwa Ma Encoder akanema

Kuti ma encoders anu amakanema azitha kugwira ntchito modalirika, kuthetseratu ndi kukonza ndikofunikira. Malangizo ena ogwiritsira ntchito bwino encoder:

Onetsetsani Kutentha Kwambiri

Ma encoder amakanema amatulutsa kutentha chifukwa cha kuchuluka kwa ntchito yoponderezedwa ndi njira zotsatsira. Ngati encoder yanu ikuwoneka kuti ikugwetsa mafelemu kapena ikuchita mosakhazikika, kutentha kwambiri kumatha kukhala vuto. Onetsetsani kuti encoder yanu ili pamalo olowera mpweya wabwino, mafani ndi polowera mpweya mulibe fumbi, ndipo zida zonse zoziziritsa zikugwira ntchito bwino. Kwa ma encoder a rackmount, kuwongolera kutentha kwapakati pa data ndi kufalikira ndikofunikira. 

Sinthani Firmware ndi Mapulogalamu

Opanga ma encoder nthawi zonse amatulutsa zosintha za firmware ndi mapulogalamu kuti akhazikitse zovuta zachitetezo, kukonza zolakwika, kukonza bata ndikuwonjezera zatsopano. Kusunga makina anu osindikizira amakono ndi mitundu yaposachedwa ya firmware ndi kukhamukira kwa mapulogalamu kumathandiza kupewa zovuta zomwe zingachitike ndikuwonetsetsa kuti zida zonse zikugwirizana. Zosintha zambiri zitha kumalizidwa kudzera pa encoder mawonekedwe kapena mothandizidwa ndiukadaulo. 

Yesani ndi Kuwongolera

Pazochitika zofunikira kwambiri zotsatsira, kuyesa encode yanu yonse ndi mayendedwe operekera pasadakhale ndikofunikira. Sanjani zolowa zonse, zotuluka, zosintha zosintha, malo omwe akutsatiridwa ndi njira zolephera kuti mutsimikizire magwiridwe antchito ndikusintha momwe zingafunikire. Yang'ananinso kuti muli ndi zosafunika pazigawo monga magwero a magetsi, ma intaneti ndi ma netiweki ogawa. Kuyesa kuyesa kwanthawi yayitali m'masiku oyambira kusewerera kungathandize kutsimikizira kuti chilichonse chikuyenda bwino mukakhala.  

Yang'anirani Kagwiritsidwe Ntchito ndi Kachitidwe

Ma encoder akatswiri ambiri amapereka ma metric ogwiritsira ntchito, kudula mitengo ndi zidziwitso kuti azindikire zolakwika pakugwira ntchito. Yang'anirani zinthu monga kagwiritsidwe ntchito ka CPU, kugwiritsa ntchito kukumbukira, ziwerengero zamayimbidwe amtundu ndi malo a disk nthawi zonse kuti muwonetsetse kuti ma encoder akugwira ntchito bwino. Khazikitsani zidziwitso za ma metrics omwe akuwonetsa zovuta zomwe zingachitike monga kuchedwetsa kwambiri, mafelemu otsika kapena kuchuluka kwakukulu kwa zolakwika za zipata 502. Yang'anani ma spikes aliwonse osadziwika kapena kutsika kwazinthu ndi kusuntha kwabwino.

Konzani Kukonza Nthawi Zonse

Kwa ma encoder omwe ali pamalopo, kupanga dongosolo lokonzekera nthawi zonse ndikofunikira kwambiri. Izi zikuphatikizapo:

• Kupukuta mpweya ndi mafani kuti muteteze kutenthedwa kwa fumbi 
• Kuyang'ana kuti ma chingwe onse ndi otetezeka komanso osawonongeka 
• Kuchita zowunikira za Hardware kuti muwone zovuta zomwe zingachitike msanga
• Kukhazikitsanso zigawo zofananira monga makhadi ojambulira kuti mukhazikitse kulumikizana kotetezeka    
• Kuwonongeka kwa disk ndikuchotsa mafayilo osungidwa osafunikira kuti mukwaniritse zosungirako 
• Ngati rackmount, kuyendera njanji, thireyi ndi m'mabulaketi kuti unsembe bwino 

Pochita njira zanthawi zonse zothetsera mavuto, kuyang'anira encoder yanu mwachangu ndikukonza nthawi zonse, zovuta zambiri zodziwika zitha kupewedwa palimodzi. Ntchito zanu zotsatsira zimadalira akatswiri osindikiza makanema, kotero kuwasunga m'malo abwino ogwirira ntchito ndikofunikira kuti muchite bwino. Kugwira ntchito limodzi ndi magulu othandizira aukadaulo, kuyesatu pasadakhale komanso kukhala pamwamba pazosintha kumakupatsani chitetezo kuti owonera anu azitha kuwonera bwino pakakhala zofunika kwambiri. 

Kutsiliza

Monga mukuwonera, ma encoders amakanema amapanga maziko osinthira makanema ndi makanema padziko lonse lapansi. Iwo ali ndi udindo wosintha zithunzi zosasinthika kukhala mawonekedwe a digito oyenera kuseweredwa pa intaneti ndi zida zolumikizidwa. Pagulu lililonse lomwe likukhamukira mavidiyo amoyo kapena omwe akufuna pa intaneti, kuyika ndalama panjira yolumikizira akatswiri ndikofunikira. 

FMUSER imapereka ma encoder amakanema amtundu wa hardware kuti azitha kutsatsa, kuwulutsa, IPTV ndi AV pagawa IP. Ndi chithandizo cha mawonekedwe monga H.264, H.265, MPEG-2 ndi 4K 60fps amadutsa, ma encoder a FMUSER amagwiritsidwa ntchito ndi makampani akuluakulu a TV, makampani, mabungwe a maphunziro ndi maboma padziko lonse lapansi.

Kaya mukufuna chosindikizira chosunthika kuti muzitha kuwonera zochitika pompopompo, chojambulira chamitundu yambiri kuti chiziwulutsidwa kapena mutu wa IPTV kuti muzitha kuyang'anira mazana a makamera a IP, FMUSER ili ndi mayankho aukadaulo omwe ali ndi chithandizo chambiri komanso kudalirika.
