Ma waena o nā hiʻohiʻona mahalo nui ʻia, hoʻohana ka HTTP live streaming platform i ka ke kahe adaptive ʻenehana e kuhikuhi ana i nā mea kau inoa e kahe ana ma o ka hāʻawi ʻana iā lākou i nā lawelawe i koi ʻia a me nā lawelawe kaila ola ma waena o nā hāmeʻa Apple āpau.

No ke aha mākou e pono ai e hele no kahi ʻenehana HLS Player?

Ma mua o ko mākou lele ʻana i ke kaʻa kaʻa o ka hoʻohana ʻana i Mea pāʻani HLS e ʻike mua iā mākou i nā kumu mua e hoʻohana ai kekahi iā ia ma mua.

  • Kanaha - Mea pāʻani HLS Loaʻa iā ia kahi ubiquity nui e kākoʻo maoli i kēlā me kēia polokalamu kele pūnaewele akā ʻaʻole i kaupalena ʻia iā Quicktime, Safari, nā polokalamu kele pūnaewele Google Chrome, Microsoft Edge, Linux a me nā paepae Microsoft e hoʻolilo iā HLS i koho maikaʻi loa i waena o kāna mau hoʻokūkū. 
  • Hana pololei - Hāʻawi ke kahe HLS i nā ʻike leo a me nā wikiō ma o ka pūnaewele i kahi ala maʻalahi. ʻO ka hapa nui o ka lawelawe wikiō wikiō e hiki ai i ka mākeke i kēia lā e koi ʻia e hele ma waena o kahi kaʻina o ka hana mai ka hoʻonohonoho lako paʻa i ka encoding polokalamu akā ma ka ʻaoʻao ʻē aʻe. HLS e kahe ana hāʻawi ʻia i nā hāmeʻa āpau e nā faile M3U8. Aia nā faila M3U8 i kahi o ka faila media ma kahi papa inoa playlist, kahi e mālama ʻia ai ma ke ʻano he faila i kahi mīkini kūloko a me kahi URL no ke kahe ola.

  1. Hoʻolālā Bitrate Adaptive - Inā ʻoe e hoʻohana nei i kahi pūnaewele uea a i ʻole uwea ʻole ka ʻenehana adaptive bitrate streaming e ʻae i nā mea hoʻohana e hoʻololi i ka wikiwiki wikiwiki e like me ka dynamically a hōʻoia i ka maikaʻi o ke kahe me ka ʻole o kahi kahakaha. Manaʻo ʻia nā mea pāʻani HLS ma ke ʻano he ʻoi loa paepae hoʻolele wikiō kahi e hiki ai i nā mea hoʻohana ke ʻike i kahi kiʻi kūpono piha me ke kōkua o kēia ʻenehana HLS ma nā bitrates haʻahaʻa a hiki iā ia ke hāʻawi iā html5 ola wikiō i nā wikiō i kahi ala pono ʻole. No laila, noho ka ʻenehana HLS ma ke ʻano he kūlana gula no ke kahe ola ʻana i ka leo a me ka ʻike wikiō.
  2. Pāʻani Pōʻani Multiple - I kēia mau lā a me ka makahiki, pono i ka mea hoʻokani wikiō e hoʻokahe i nā ʻike me ka maikaʻi maikaʻi ʻole no ka mea e ʻike ʻia nā mea e pono ai. Hoʻokani ka mea pāʻani HLS i ke kahe kahe o kēia manawa no ke kahe media e hoʻohana nei i ka ʻenehana hou. HLS kahawai i nā kelepona uila, papa, PC a me nā hāmeʻa ʻē aʻe i kēlā me kēia ʻano e like me MP4, M3U8 a i ʻole MPEG dash a i ʻole nā ​​ʻano ʻano ʻē aʻe.  
  3. HLS & Dash Adaptive -ʻO DASH ke ʻano hoʻohālikelike kahe e kahe ana ma kahi o ka HLS kahe kahe. Hāʻawi ka DASH adaptive i ka kahe maʻamau o ka honua i hoʻokumu ʻia ma ka HTTP protocol. Me HLS a me Dash Adaptive streaming technology, hiki ke hāʻawi ʻia i nā ʻike media mai nā kikowaena pūnaewele maʻamau ma o ka pūnaewele.
  4. Hoʻopiʻi HD nunui-bitrate - Hoʻohana maikaʻi ka ʻenehana HLS i ka ʻenehana encoding multi-bitrate kahi i hoʻonohonoho ʻia a hoʻokumu ʻia ai ke kumu wikiō i loko o nā bitrates like ʻole a hoʻolaha ʻia i ka Pūnaewele Hoʻolālā ʻIke i koho ʻia. ʻO kēia ʻano multi-bitrate a i ʻole nā ​​kahawai he nui e hoʻokumu i kēia mau mea pāʻani wikiō i waena o kāna mau mea hoʻokūkū. Hāʻawi kēia i nā mea nānā e koho i kahi kahawai e like me kā lākou bandwidth i kahi ala seamless. ʻO kahi laʻana, inā he ʻoi aku ka kiʻekiʻe o ka bander view, hiki iā lākou ke koho iā 1080p60 a i ʻole no ka bandwed medium hiki iā lākou ke koho iā 480p a i ʻole 360p a pēlā aku.
