WebM → DTS

Yebo, futhi kufanelekile ukuhlela. Izifomethi zombili ziyi-lossy, ngakho-ke i-DTS encoder isebenza kusuka kumsindo osele udlulele engxenyeni eyodwa ye-psychoacoustic, futhi iziphakamiso zayo zihlanganisa isiqephu sokuqala. Ku-192 kbps noma ngaphezulu, imiphumela ihlala icacile kakhulu. Uma une-lossless master nganoma yikuphi, uku-encoding i-DTS kusuka kulo kunciphisa ukudlula okuphindiwe ngokuphelele. WebM idinga ukucophelela: VP8 noma VP9 ividiyo (AV1 manje) nge Vorbis noma Opus umsindo, futhi akukho okuthile okuningi. I-DTS iyisandi esiningi esilahlekile esingenazo izintambo esiphezulu kakhulu kuna-AC-3 — ngokuvamile 768 kuya ku-1509 kbps nge-5.1.

Ngokuvamile akunjalo. WebM i-decoded yinoma yini, kufaka phakathi izimoto eziphezulu nezidlali ezikhulu; DTS idinga isofthiwe eyazi i-codec, esizohlala i-hardware ehlala ikhona. Uma indawo esiya kuyo imoto ye-stereo noma umdlali ophathekayo, lokhu kuyisinqumo esiqinile sokuhlala ku WebM. I-DTS license isho ukuthi i-TV, i-soundbars kanye ne-browser ngayinye iyisiyeka, ngakho-ke kufanele ibe yi-AAC noma i-AC-3 ukuze isebenziseke.

Ngephutha umsindo 0 (umsindo wokuqala, ngokuvamile umsindo omkhulu). Uma WebM wakho ufaka umlayezo, ama-dubs, noma umsindo ochazayo kuma-tracks angeziwe, umkhethi othuthukisiwe "umsindo" ukuvumela ukuthi ukhethe 1, 2, 3... ngokucacile. Uhlu lwe-track lubonisa ukufinyelela kokubuka kuqala ukuze ungakhetha ngokuzifihla.

Iphutha DTS i-bitrate yi-192 kbps (icacile kuma-earphones amaningi). Nciphisa ku-320 kbps nge-audiophile output, noma 96-128 kbps ngezwi/podcast lapho ihele elincane liyisisekelo. Ama-DTS angeke alahlekile (WAV, FLAC) agweme ukumiswa kwe-bitrate futhi agcine yonke isampula.

Uma i DTS ifomethi ingekho lutho (WAV, FLAC, ALAC), yonke isampula yangempela igcinwa. Uma i DTS ingekho lutho (MP3, AAC, OGG, Opus), i-codec icindezela futhi — ku-192 kbps ushintsho alukwazi ukulizwa kuningi kwezithameli; ku-96 kbps ungalizwa ama-cymbals noma ama-sibilans abandayo. I-WebM i Container ayinaso isikhundla kulolu hlelo — ukumiswa kwe-codec kuphela okubalulekile.

Ngokungagqibekanga yebo — 48 kHz WebM umsindo ushintsha ube 48 kHz DTS umsindo, 44.1 kHz ushintsha ube 44.1 kHz. Uma ufuna ukuncipha kwesampula ukuze kusebenze (isibonelo 96 kHz studio masters kuya ku 44.1 kHz CD-quality DTS) isampula-rate dropdown yenza lokhu ngekhwalithi ephezulu yokusatshalaliswa kabusha.

Yebo — susa isibaya se WebM amafayela endaweni yokulayisha futhi siqhube ukukhishwa ngokufanayo. I-Premium ithola abasebenzi abafanayo abaningi; ku-100-file batch (uhlelo lwemiculo-video olujwayelekile) lokhu kuyinto ehlukile phakathi kwamasekondi angama-90 namaminithi angama-8.

Umsindo demux + transcode usebenza ngokushesha kakhulu kunakhodi yevidiyo - ngokuvamile 5-15% yesikhathi somthombo. Ihora le-1 WebM -> DTS liphele ngemizuzu engu-3-9 ku-pipeline ejwayelekile. Uma i-DTS codec ifana ne-source codec esekwi-WebM (ejwayelekile ye-AAC ngaphakathi kwe-MKV / MP4), iyi-remux ecacile futhi isebenza ngemizuzu.

Uma ihele WebM ligcina i-stream metadata (umculi, isihloko, i-album), sikopa lezi zindawo kuDTS isitoreji lapho ifomu lixhasa amathegi. ID3v2 (MP3), amazwana we-Vorbis (OGG, FLAC), ama-MP4 atoms (AAC / M4A), RIFF INFO (WAV) wonke abhalwe. Ukungabi nathegi WebM kwenza DTS — sebenzisa i-Mp3tag noma i-Picard emva-kwe-ukukhishwa ukuze uthuthukise.

Yebo — imodeli yobumfihlo efanayo nezo zonke iziguqulo. Umsuka WebM nesokudla DTS zicutshungulwa kubasebenzi abahlukanisiwe futhi zicishwe ngaphakathi kwemizuzu. Asikwazi ukudlala, ukugcina, noma ukuhlanganisa okuqukethwe. Bona /privacy/.

Kuyinto evamile kakhulu ukungqubuzana kwe-stream-index — WebM yakho iqukethe i-multi-track audio layout futhi siyikhuphule i-stream engalungile (isibonelo, i-audio track echazayo emnyama endaweni ye-main mix). Phinda uqhube nge-"audio stream" ethuthukisiwe ekhethiwe ebekwe kwi-index efanele, noma khetha "zonke iziqukathi" ukukhishwa kwe-track ngayinye njengefayela elihlukile DTS.
