Kuyini i-codec futhi ziyini na?

Kuyi-Internet ngokuvamile ungase uthole umbuzo "lokho amakhodekhi". Ukuze siphendule ke, masikhumbule wekhodi idatha digital.

Ngamunye wethu bebona okungenani kanye ividiyo kukhompyutha yakho, idivayisi yeselula noma isidlali somculo. Futhi ukulalela amathrekhi alalelwayo kwanda ukuze manje, ngaphandle ezitaladini zalelo dolobha, kunzima yini ukuhlangabezana nomuntu-headphone. Ngesikhathi abantu abambalwa efanayo cabanga labo izibalo okuyinto kufanele athobele emaphakathi processor ihluzo ikhadi, ekulungiseleleni isithombe noma umsindo. Kunengqondo ukuphetha ngokuthi kokusebenzisa izibalo? Kungokufanayo ikhasethi abadlali ngaphandle kokuba zonke izilimi (angafaki ezikhethekile), ngokuphawulekayo abhekana ngayo imisebenzi yabo. Nokho, ukuqhathanisa okunjalo ayilungile, ngoba lonke ifayela libhekene hhayi ubude tape ngamamitha, kanye umthamo -mega terabytes -Oral, kanye isikhala kwi abezindaba ngeke uthole ngokwanele. Ngokuvamile yonke imibuzo zinyamalale kanye lizwakalise nenkundla kwevidiyo digital: elingu-1 HDTV ejwayelekile imayelana 3 GB. Ngakho manje wonke ividyo ne-odiyo icutshungulwe izinhlelo ezikhethekile ukuthi unciphise usayizi wefayela ngokususa (Ukuminyanisa, kokucindezelwa) ayingxenye idatha non-abalulekile. Kukhona izinhlelo eziningi ezinjalo, kodwa kusetshenziswa kakhulu embalwa nje. Ngokwesibonelo, video codecs - kuyinto DivX, Xvid, x264, njll Kodwa emkhakheni umsindo ezihlukahlukene ngaphansi .. Empeleni, lapha ukubusa amakhodekhi elandelayo yomsindo: MPEG Layer version 3, AC-3 futhi uncompressed WAV format. Manje isilinganiso computer umsebenzisi ukuthola isibonelo ekusakazeni uncompressed cishe kungenakwenzeka.

Impendulo yombuzo "kuyini ngekhodekhi" kuyinto: ngekhodekhi - uhlelo encane ezikhethekile noma umtapo (DLL), esebenza njengesikhali ukufaka ikhodi (kokucindezelwa) namafayela emagama, ukusakaza multimedia. Ake sithi umsebenzisi ivule ifayela levidiyo isofthiwe umdlali. Isakhiwo ifayela ngalinye ulwazi iyunithi ekhombisa nge kokucindezelwa ngekhodekhi wawenziwa. Ngesisekelo Imininingwane umdlali ukufunda izicelo idatha yesistimu yokusebenza kundawo ngekhodekhi futhi ulisebenzise ukuqopha ukusakaza, outputting isiqophi esikrinini. Uma uhlelo codec engekho, khona-ke bengakwazanga ukudlala emuva umlayezo. Ikesi ekhethekile - ividiyo umsindo noma nje kuphela.

Ukwazi lokho amakhodekhi kungaba wusizo ukuze kutholakale, ngayo nefunda ngayo ifayela target esiye onomfutho. Lokhu kuzodinga Uhlelo mediainfo, GSpot noma efana othi block idatha. Ziningi, ngezinye izikhathi ngisho isicelo nokusebenza ngamafayela multimedia (Ifomethi Factory) ukuhlinzeka ithuba elinjalo. Thina ukuqondisa isikhombisi ifayela oyifunayo futhi ushayele imenyu. Ngo isixhumanisi "Buka" noma "Thumela" inketho kuyoba kudingekile. Ngokulandelayo, icala elincane - ukulanda futhi ifake lezi amakhodekhi.

Ngubani ukuthi yini amakhodekhi kalula ukuxazulula inkinga inoperability amafayela multimedia. Awudingi lokumba izici khodi ethile noma ukufunda ikhasi multi-manual. Isixazululo silula - ukulanda futhi ifake ekhethekile iqoqo mahhala amakhodekhi. Okwamanje omunye the best - lena K-Lite Ikhodekhi Pack. Setha ikhona izinguqulo eziningana, ngakho-ke kungcono ukuthi ube nozwelo kwamamegabhayithi ambalwa wachitha, futhi ngokushesha thwebula Pack Mega. Uma ufaka Wabasaqalayo ungasebenzisa izilungiselelo kunjiniyela Kunconywa, kanye nabasebenzisi eziphambili bayacelwa ukwenza aveze ukuthi kuyadingeka ukuze ubhalise ohlelweni. Ngemva kokufaka i-K-Lite zonke amakhodekhi uzobe ebhalisiwe uzokwazi ukuxhuma ngokuzenzakalela isidlali eyicela. Okungukuthi, ukuba khona amakhodekhi umsebenzisi ngokuphelele "okusobala".

Kukhona enye indlela esingathola ukudlala amafayela soxhumanoningi. Ngenxa yalesi kukhona abadlali ekhethekile (PotPlayer, VLC, njll). Algorithms ekunika emagama zibeka.
