Inā ʻoe i hana i kekahi live streaming, pono ʻoe e kamaʻāina i nā protocol streaming, ʻoi aku ka RTMP, ʻo ia ka protocol maʻamau no ka streaming live.Eia nō naʻe, aia kahi protocol streaming hou e hana nei i kahi buzz i ka honua streaming.Kapa ʻia ʻo ia, SRT.No laila, he aha ka SRT?
Kū ʻo SRT no Secure Reliable Transport, kahi protocol streaming i hoʻomohala ʻia e Haivision.E hōʻike wau i ke koʻikoʻi o ka streaming protocol me kahi laʻana.Ke wehe kekahi i YouTube Live e nānā i nā kahawai wikiō, hoʻouna kāu PC i ka "noi e hoʻohui" i ke kikowaena.Ma ka ʻae ʻana i ka noi, hoʻihoʻi ke kikowaena i ka ʻikepili wikiō i hoʻokaʻawale ʻia i ka PC kahi i hoʻopaʻa ʻia ai ka wikiō a hoʻokani ʻia i ka manawa like.ʻO ka SRT kahi protocol streaming e pono e hoʻomaopopo ʻia nā mea ʻelua no ke kahe wikiō ʻole.Loaʻa i kēlā me kēia protocol kona pono a me ka RTMP, RTSP, HLS a me SRT kekahi o nā protocol kaulana loa i hoʻohana ʻia i ke kahe wikiō.
No ke aha ʻo SRT ʻoiai ʻo RTMP kahi protocol streaming paʻa a hoʻohana mau ʻia?
No ke aʻo ʻana i ka maikaʻi a me ka maikaʻi o SRT a me kāna mau hiʻohiʻona, pono mākou e hoʻohālikelike iā ia me RTMP.ʻO RTMP, ka mea i ʻike ʻia ʻo Real-Time Messaging Protocol, kahi protocol streaming i hoʻopaʻa ʻia me ka inoa no ka hilinaʻi ʻana ma muli o kāna mau mea hiki ke hoʻouna hou ʻia ʻo TCP-based pack a me nā buffer hiki ke hoʻololi ʻia.ʻO RTMP ka protocol streaming maʻamau i hoʻohana ʻia akā ʻaʻole i hōʻano hou ʻia mai ka makahiki 2012, no laila hiki ke hoʻololi ʻia e SRT.
ʻO ka mea nui loa, ʻoi aku ka maikaʻi o ka SRT i ka wikiō pilikia ma mua o RTMP.Hiki i ke kahe ʻana i ka RTMP ma luna o nā ʻoihana pūnaewele haʻahaʻa haʻahaʻa hiki ke hana i nā pilikia e like me ka buffering a me ka pixilation o kāu kahawai ola.Pono ʻo SRT i ka bandwidth liʻiliʻi a hoʻoponopono wikiwiki i nā hewa ʻikepili.ʻO ka hopena, e ʻike kāu poʻe nānā i kahi kahawai ʻoi aku ka maikaʻi, me ka liʻiliʻi o ka buffering a me ka pixelization.
Hāʻawi ʻo SRT i ka latency end-to-end ultra-haʻahaʻa a hāʻawi i ka wikiwiki ʻo 2 - 3 mau manawa wikiwiki ma mua o RTMP
Hoʻohālikelike ʻia me RTMP, hāʻawi ka SRT streaming i ka latency haʻahaʻa.E like me ka mea i ʻōlelo ʻia ma ka pepa keʻokeʻo (https://www.haivision.com/resources/white-paper/srt-versus-rtmp/) i paʻi ʻia e Haivision, ma ka hoʻāʻo like ʻana, he lohi ka SRT he 2.5 - 3.2 mau manawa ma mua o RTMP, ʻo ia ka hoʻomaikaʻi nui.E like me ka mea i hōʻike ʻia ma ke kiʻikuhi ma lalo nei, ʻo ka pahu polū e hōʻike ana i ka hana SRT, a hōʻike ka pahu ʻalani i ka latency RTMP (ua hoʻokō ʻia nā hoʻokolohua ma nā wahi kikoʻī ʻehā, e like me Kelemānia a Australia a me Kelemania i ka US).
Hōʻike mau i ka hana ʻoi aku ka maikaʻi ma kahi pūnaewele hilinaʻi ʻole
Ma waho aʻe o kona latency haʻahaʻa, pono e haʻi ʻia hiki ke hoʻouna ʻia ʻo SRT i kahi pūnaewele maikaʻi ʻole.Ua kūkulu ʻia ka ʻōnaehana SRT i nā hana e hōʻemi i nā hopena ʻino i hana ʻia e ka piʻi ʻana o ka bandwidth, packet loss, etc., pēlā e mālama ai i ka pono a me ka maikaʻi o ke kahawai wikiō ma nā pūnaewele hiki ʻole ke ʻike ʻia.
Nā pōmaikaʻi i hiki iā SRT ke lawe mai?
Ma waho aʻe o ka latency ultra-haʻahaʻa a me ka hiki ke hoʻololi i ka ʻenehana pūnaewele, aia kekahi mau pono ʻē aʻe i hiki iā SRT ke lawe iā ʻoe.No ka mea hiki iā ʻoe ke hoʻouna i nā wikiō ma ke ala ʻike ʻole, no laila ʻaʻole pono nā pūnaewele GPS pipiʻi, no laila hiki iā ʻoe ke hoʻokūkū ma ke ʻano o kāu kumukūʻai lawelawe.I nā huaʻōlelo ʻē aʻe, hiki iā ʻoe ke ʻike i ke kamaʻilio duplex interactive ma kēlā me kēia wahi me ka loaʻa ʻana o ka Pūnaewele.Ma ke ʻano he protocol streaming wikiō, hiki iā SRT ke hoʻopaʻa i ka ʻikepili wikiō MPEG-2, H.264 a me HEVC a me kāna ʻano hoʻopunipuni maʻamau e hōʻoia i ka pilikino ʻikepili.
ʻO wai e hoʻohana iā SRT?
Hoʻolālā ʻia ʻo SRT no nā ʻano hoʻoili wikiō like ʻole.E noʻonoʻo wale i loko o kahi keʻena hālāwai kūkā nui, hoʻohana nā mea a pau i ka pūnaewele like e paio ai no ka pili pūnaewele.ʻO ka hoʻouna ʻana i nā wikiō i ke keena hana ma luna o kahi ʻoihana paʻa, e hoʻohaʻahaʻa ʻia ka maikaʻi o ka lawe ʻana.Loaʻa paha ka nalowale ʻana o ka ʻeke i ka wā e hoʻouna ana i ke wikiō ma luna o kahi pūnaewele paʻa.ʻO SRT, ma kēia kūlana, he mea maikaʻi loa ia i ka pale ʻana i kēia mau pilikia a hāʻawi i nā wikiō kiʻekiʻe i nā encoders i koho ʻia.
Nui nā kula a me nā hale pule ma nā wahi like ʻole.No ke kahe ʻana i nā wikiō ma waena o nā kula ʻē aʻe a i ʻole nā hale pule, ʻaʻole ʻoluʻolu ka ʻike ʻike inā loaʻa kahi latency i ka wā e kahe ana.Hiki i ka Latency ke lilo i ka manawa a me ke kālā.Me SRT, hiki iā ʻoe ke hana i nā kahawai wikiō maikaʻi a hilinaʻi ma waena o nā wahi like ʻole.
He aha ka SRT he protocol streaming maikaʻi?
Inā pōloli ʻoe i ka ʻike a makemake ʻoe e ʻike hou aʻe e pili ana i nā mea maikaʻi ma luna aʻe e pili ana iā SRT, e hāʻawi nā paukū e hiki mai ana i nā wehewehe kikoʻī.Inā ʻike mua ʻoe i kēia mau kikoʻī a i ʻole makemake wale paha, hiki iā ʻoe ke hoʻokuʻu i kēia mau paukū.
ʻO kahi ʻokoʻa nui ma waena o RTMP a me SRT ʻo ka loaʻa ʻole o nā timestamp ma nā poʻomanaʻo packet stream RTMP.Loaʻa i ka RTMP nā kaha manawa o ke kahawai maoli e like me kona helu kiʻi.ʻAʻole loaʻa kēia ʻike i kēlā me kēia ʻeke, no laila pono ka mea lawe RTMP e hoʻouna i kēlā me kēia ʻeke i loaʻa i loko o kahi manawa paʻa i ke kaʻina decoding.No ka hoʻomaʻamaʻa ʻana i nā ʻokoʻa i ka manawa e hele ai nā ʻeke hoʻokahi, pono nā pale nui.
ʻO SRT, ma ka ʻaoʻao ʻē aʻe, loaʻa kahi hōʻailona manawa no kēlā me kēia ʻeke.ʻO kēia ka mea e hiki ai i ka leʻaleʻa o nā hiʻohiʻona hōʻailona ma ka ʻaoʻao hoʻokipa a hoʻemi nui i ka pono no ka buffering.I nā huaʻōlelo ʻē aʻe, ʻo ka bit-stream e haʻalele ana i ka mea hoʻokipa e like me ke kahawai e hele mai ana i ka mea hoʻouna SRT.ʻO kekahi ʻokoʻa koʻikoʻi ma waena o RTMP a me SRT ʻo ia ka hoʻokō ʻana i ka packet retransmission.Hiki iā SRT ke hoʻomaopopo i kahi ʻeke i nalowale ma kāna helu kaʻina.Inā ʻoi aku ka nui o ka delta ma mua o hoʻokahi ʻeke, hoʻomaka ka hoʻouna hou ʻana o kēlā ʻeke.Hoʻouna hou ʻia kēlā ʻeke kikoʻī e mālama i ka latency a me ka haʻahaʻa.
No ka ʻike hou aku e pili ana i nā kikoʻī ʻenehana, e kipa i ka pūnaewele mana o Haivision a hoʻoiho i kā lākou ʻike loea (https://www.haivision.com/blog/all/excited-srt-video-streaming-protocol-technical-overview/).
SRT palena
Ma hope o ka ʻike ʻana i nā pono he nui o SRT, e nānā kākou i kona mau palena i kēia manawa.Ma waho aʻe o Wowza, ʻaʻole i loaʻa iā SRT ka nui o nā platform streaming manawa maoli i kā lākou ʻōnaehana no laila ʻaʻole hiki iā ʻoe ke hoʻohana pono i kāna mau hiʻohiʻona maikaʻi mai ka hopena o ka mea kūʻai aku.Eia nō naʻe, ʻoiai ʻoi aku ka nui o nā ʻoihana a me nā mea hoʻohana pilikino e hoʻohana i ka SRT, manaʻo ʻia e lilo ʻo SRT i ke kūlana wikiō e hiki mai ana.
Hoʻomanaʻo hope
E like me ka mea i ʻōlelo ʻia ma mua, ʻo ka hiʻohiʻona nui o SRT ʻo kona latency haʻahaʻa akā aia kekahi mau mea ʻē aʻe i ke kahe holoʻokoʻa holoʻokoʻa e hiki ke alakaʻi i ka latency a me ka hopena maikaʻi ʻole o ka nānā ʻana e like me ka bandwidth network, codec device a me nā mea nānā.ʻAʻole hōʻoiaʻiʻo ʻo SRT i ka latency haʻahaʻa a me nā mea ʻē aʻe e like me ke kaiapuni pūnaewele a me nā hāmeʻa streaming pono e noʻonoʻo ʻia.
