WebM Tuhinga o mua HLS Ngā Pātai Auau mō te Tahuritanga
He pēhea te tahuri i a au i te WebM ki te HLS me te kore whakawaehere i te rerenga ataata?
+
Ki te taea e ngā WebM me HLS ngā kāwai te mau i te pūrere ōrite (H.264, H.265, VP9, AV1), ka hoki te whakarerekē ki tētahi remux: ka tāruatia ngā rerenga taketake ki roto i te HLS kāwai, ā, ko te wrapper anake e huri ana. Ko te remux o te 1 GB WebM ki HLS e mutu ana i roto i ngā wā 5-15 me te ngaronga āhuatanga kore. He whāiti te WebM: VP8, VP9 rānei te ataata (AV1 ināianei) me te Vorbis, te oro rānei, me ētahi atu. Ko te rerenga HLS he.m3u8 e tohu ana ki tētahi tīwae o ngā wāhanga H.264, HEVC rānei i ngā wāhanga maha, kia taea ai e te kaiwhakaari te huri i te āhuatanga i waenganui i te whakataetae.
Ka taea e te HLS te pupuri i neke atu i tētahi rererangi oro?
+
Heoi, he whakawhānui tūturu i runga i te WebM. HLS e whakaaro ana ki ia rerenga oro hei rererangi ā-ira tuatahi, kia noho ai te whāranu reo taketake, te tāruatanga me te kōrero a te kaiwhakahaere i tētahi pūranga kotahi me te kaipāpāho e whakawhiti ana i waenganui i a rātau i te tono. E āhei ana te HLS ki te whakawhāiti i te whakawhāiti o te kaitirotiro i te wā tūturu, ā, ko te āhua kotahi anake o te whakateretanga o Safari me te tautoko ā-iwi o iOS.
He mea mauī te HLS, he pūkōrero rānei, ā, ka hurihia te mea e whiwhi ana au?
+
Ka huri tēnei i te mea e tūmanakohia ana mai i te pūkete huaputa. Ko tētahi taha o tēnei tahuritanga e kiia ana he waehere, ehara i te whākōkī, nō reira ko te mea e hoki ana ko te rerenga ira i roto i te mea e tika ana — i te nuinga o te MP4, MKV rānei. Ko te whakaroanga e whakaatu ana i te mea; ko te pūkōrero te mea e whakatau ana i te rahi o te pūkete, ā, i reira ka whakapāpāhotia.
Ka ora te oro-maha-rangirangi ki te tahuritanga WebM ki HLS?
+
He — ko ia whakataki oro i roto i te WebM (whakaaro a te kaiwhakahaere, reo whirinoa, oro whakaahua) ka tiakina ki te HLS ina tautokona e te pūrere te oro-maha. MKV me MOV e whakahaere ana i ngā whakataki oro kāore i te whakawātea; he maha ngā MP4 e tautoko ana, engari ko ētahi kaiwhakaari pūrere e kite ana i te whakataki 1 anake; Ka whakawāteatia te WebM i te whakataki Opus / Vorbis kotahi. Ko HLS te Pāpāho Ā-Wā HTTP o Apple - ehara i te faila engari he pūrākau whakatangitangi me tētahi pūrākau o ngā wāhanga pāpāho poto.
E tiakina ana ngā pūrere subtitles ina tahuritia te WebM ki te HLS?
+
Ka ora ngā whakahuatuhi māmā (ngā rererangi ka tīpakohia) ina taea e HLS te mau i a rātou: MKV kei roto i te SRT, ASS, SSA, PGS, VobSub māori; MP4 kei roto anake i te mov_text (he hanga whakawātea). Ko te tahuritanga o tētahi MKV me ngā whakahuatuhi āhua ASS ki MP4 ka whakaiti i a rātou ki te mov_text, ka whakarewa rānei i a rātou. Ko ngā whakahuatuhi matatini (i whakarewatia ki roto i te ataata) ka mau i a rātou ahakoa pēhea.
E WebM ki HLS e pupuri ana i ngā tohu wāhanga / whakatere āhua DVD?
+
Ka whakawhitia ngā raraunga meta i waenganui i te WebM me te HLS ina tautokona e ngā kāwai e rua tētahi ngota wāhanga (MKV, MP4, MOV). Ka penapena te WebM i ngā wāhanga i roto i tētahi kōpaka Matroska-hōpū, kia mārama ai ngā wāhanga MKV <-> WebM. Kāore he whakapūtā wāhanga a AVI, nā reira ka tahuri te tahuri AVI ki te HLS i tētahi pūranga kāore i te whakarārangi, engari rawa ka tāpiri i ngā tohu ā-ringa.
He aha mo ngā whakataki MKV (whakatika, whakataki) ina haere mai te WebM ki te HLS?
+
Ko MKV te mea anake e pupuri ana i ngā pūkete whakapiripiri (ngā tātuhi TTF mō ngā tātai ASS, ngā toi kāwai JPG, ngā tāurunga PDF i whakamāoritia). E haere ana mai i te WebM ki te HLS ka whakapeka ēnei tātai ina kore te HLS he MKV — ka tahuri ngā rerenga taketake, engari ka noho te utu whakapiripiri i te pūtake. Whakataki WebM hei tiaki i ētahi atu tātai mēnā e whakawhirinaki ana ki ngā tātai whakapiripiri.
He aha te pūrere pūrere e whakamahia ana e te HLS?
+
E kōwhiritia ana te pūnaha waeheretanga pūnoa hei ōrite ki te HLS kaitakawaenga: MKV ngā pūnoa ki H.265 (HEVC) mō te whakawhāititanga pai ake; MP4 ngā pūnoa ki H.264 mō te tautoko pūrere whānui rawa; WebM ngā pūnoa ki VP9; AVI e whakamahi ana i te MPEG-4 ASP (DivX/Xvid lineage). Ka whakawātea mā te whakawātea codec hōhonu — Kei te wātea te AV1 mō MKV / WebM i reira e hiahiatia ana e koe te whakawhāititanga nui rawa, ā, ka taea te tūmanako mā te waehere.
He pēhea te ora o HDR (HDR10, Dolby Vision) mai i te WebM ki te HLS?
+
Ko te metadata HDR takoto (HDR10 nga uara whakaaturanga matua, te taumata mārama ihirangi) e mau ana ki te HLS ina tautokona e ngā kāwai me te pūāhua kōaro i kōwhiria (HEVC, AV1 i MKV / MP4). He nui ake te pōturi o Dolby Vision — ko te tātai DV 5 / 7 / 8.1 i te WebM e ora noa ana ki te MKV me HEVC; te tahuri ki tētahi HLS kāwai kāore e mau ana i te apa DV ki te HDR10.
Ka pupuri te WebM ki te HLS kaiwhakarere i te auautanga whārite tāupe (VFR)?
+
MKV me te WebM e whakataki ana i ngā rārangi wā-whāiti tūturu, ā, ka whakahaeretia e VFR māori, nā reira WebM VFR e ora ana ki tētahi HLS o ēnei hanga kāore i te tāurunga. MP4 e pupuri ana hoki i ngā rārangi wā, engari ko ētahi kaitapere e whakaaro ana ki te CFR; Ka whakaaturia e te tahuri tētahi "pūngao CFR" e whakamātau ana i te VFR WebM ki te 24 / 30 / 60 fps HLS mō ngā ūnga raruraru.
He aha te mea he iti iho / nui ake te HLS o ahau i te WebM i muri i te tahuri?
+
Ko te kōaro ōrite-kōrero remux e whakaputa ana i tētahi rahi tata tonu (he rerekē te taumaha o te kāwai e 0.1–2%). Ka taea e te huringa kōaro te huri i te rahi e 50%, neke atu rānei: H.264 ki H.265 e haurua ana i te faila i te āhuatanga ā-whakaahua ōrite; H.264 ki AV1 e haurua ana anō i runga i tētahi tauwhāiti pōturi. Ko te haere mai i tētahi bitrate tiketike WebM (Blu-ray rip) ki tētahi bitrate iti HLS (whakahaere i te Wīwī) ko te take tino noa mō te hinganga nui.
E whakahaere ana te WebM ki te HLS te ihirangi 4K / 8K / 60fps?
+
He, tae atu ki te 8K (7680x4320) i runga i te Premium. Ka whakahaeretia e te taumata wātea 4K (3840x2160) tae atu ki te 1 GB te tauine faila. Ko ngā tāruatanga mārō (pānga-kōkiko ōrite) o te WebM nui ki te HLS e whakawhāititia ana e te pūrere I/O, ehara i te CPU — ko te 30 GB WebM e whakawhāiti ana ki te HLS i raro i te minu, ahakoa te rongoā. Ka whakawaenga anō me te tatau o ngā pikitia.
Ko te HLS (HTTP Live Streaming) he kawa roma i whakawhanakehia e Apple mo te tuku ororongo me te riipene ataata i runga ipurangi. E whakarato ana i te roma urutau mo te pai ake o te mahi purei.
