Isifundo ngesinyathelo ngesinyathelo: guqula i-MKV ku-AVI

Mkv Yifomethi yefayela levidiyo esivele sikhulume ngayo kaningi kubhulogi le-LxA. Uma ungumsebenzisi wamawebhusayithi wokulanda amavidiyo, nakanjani uhlangabezane nalolu hlobo lwefayela ngesandiso se-.mkv. Impela eminyakeni yamuva nje sekuthandwa kakhulu futhi amavidiyo amaningi aya ngokwanda ngale ndlela, njengoba inezinzuzo ezithile njengoba sizokuphawula manje.

Kepha i-MKV ayihlali ifomethi enhle kakhulu ngokwe Compatibilidad. Uma unethebhulethi, i-smartphone, i-Android TV, i-PC, njll, ngeke ube nenkinga enkulu, ngoba kunezinhlelo zokusebenza eziningi noma abadlali abasekela amafomethi we-MKV, njengesikhungo esimnandi se-Kodi multimedia esikhulume kakhulu ngaso . Inkinga iba lapho sisebenza ngohlelo olushumekiwe noma olushumekiwe olunomkhawulo othize, njengamanye ama-TV, ama-optical player, njll., Okuvame ukuxhasa i-MPEG noma i-AVI kuphela nokuyilapho ukuguqulwa kusebenza khona.

Yini iMKV?

MKV noma IMatroska yifomethi yesiqukathi sevidiyo evulekile, amafayela akule fomethi angaba nezandiso ezahlukahlukene, kepha okuthandwa kakhulu yi-.mkv (futhi .mks, mka, .mk3d,…) njengoba sishilo ngaphambili. Isebenza njengefomethi yendawo yonke yokugcina okuqukethwe okulalelwayo nokubuka okuningi njengemibhalo engezansi ngezilimi eziningana, njll., Ngakho-ke ungayihlanganisi ne-codec yevidiyo (into nayo Ngizamile ku-LxA, umehluko phakathi kwesitsha, ifomethi ne-codec).

• Ingaqukatha ithrekhi eyodwa noma eziningi zevidiyo nomsindo.
• Ukubakhona kwe-VFR (Variable Framerate).
• Imisebenzi ethuthukile yemibhalo engezansi.
• Kungenzeka izahluko namamenyu ambalwa kufayela elifanayo.
• Izici ezinhle zokusakazwa.

• Ukuhambisana, ingenye yezithiyo ezinkulu zokufuna ukuguqula i-MKV iye ku-AVI noma enye ifomethi. Njengoba ngishilo, amadivayisi ashumekiwe noma ashumekiwe njengamanye ama-TV, ama-mp3 player, ama-mp4 player aphathekayo, i-optical BD, i-DVD player, njll.
• El usayizi Usayizi wefayela le-MKV kwesinye isikhathi mkhulu kakhulu, ama-gigabyte amaningana, okwenza kube nzima ukusebenza kahle kumadivayisi eselula angenawo amandla wokugcina aphezulu. Enye yezimo lapho kujabulisa ukuya kwenye ifomethi.

Kunoma ikuphi, kunezindlela eziningi zokuguqula.

Kuyini i-AVI?

Kuthuthukiswe ngu IMicrosoft ngo-1992, i-AVI (I-Audio Video Interleave) futhi iyifomethi yesitsha somsindo nevidiyo njengeMKV, kepha eyakudala kakhulu futhi enamaphutha amakhulu ngokuqhathaniswa neMKV. Enye yazo ukuthi iyifomethi yobunikazi, futhi nokuthi yadalwa kudala futhi ngakho-ke yayingakhelwanga ezinye zezidingo zamanje engqondweni. Njenge-MKV ingasebenzisa izinhlobo ezahlukahlukene zekhodekhi ukufaka okuqukethwe njenge-DivX, Xvid, MP3, AC3, njll.

Kepha ngaphandle kwakho konke ukungalungi nezinkinga esingaphuma kuzo ngefomethi ye-AVI, inenzuzo enkulu nebaluleke kangangoba icishe yenza konke ukungalungi kuphume. Ngikhuluma ngani ukuhambisanaKusukela iyifomethi yeMicrosoft, isabalale kakhulu futhi ithathe ukuthandwa okwedlulele kangangokuba cishe bonke abadlali namadivayisi esiwatholayo bazoyisekela. Ngakho-ke, uma beyibona, kusho ukuthi icishe ibe yifomethi yendawo yonke futhi ngeke sibe nezinkinga.

Iya kusuka ku-MKV uye ku-AVI

Uma uzithola ukulesi sidingo esiphuthumayo sokuguqula ifayela le-MKV libe i-AVI noma ukudlala kudivayisi engayemukeli noma kwidivayisi yeselula lapho sifuna ukonga khona isikhala ngokunciphisa ifayili, into enhle kakhulu ukuthi guqula i-MKV ibe yi-AVI ngalezi zinyathelo.

Into yokuqala ukuthola ithuluzi elizosisiza ukuguqula. Ukuguqula i-MKV iye ku-AVI kunezinye izindlela eziningi ku-Linux distro yethu. Enye yezintandokazi zami ukufaka (uma singenayo kakade) iphakheji ffmpeg enamandla kakhulu futhi eguquguqukayo. Noma ungakhetha i-mencoder noma i-winff, noma kunjalo konke kungamathuluzi alula futhi asebenza kusuka kukhonsoli. Khetha ithuluzi olithanda kakhulu, bese ulifaka kusuka ezinqolobaneni noma ku-App Store yediski yakho. Ngincamela ukusebenzisa i-mencoder ne-ffmpeg kulokhu, ngakho-ke ngizokukhombisa izinyathelo okufanele uzilandele nalaba ababili ...

Ukuguqulwa nge-ffmpeg

Manje njengoba sesiwafakile, sesingakwenza ngenye indlela noma ngokungenandaba. Isibonelo, uma ufuna ukukwenza usebenzisa i- the powerful ffmpeg multimedia uswidi wamasosha ummese, umyalo wokukhipha uzoba:

<br data-mce-bogus="1">

ffmpeg -i nombre_video.mkv -codec copy nombre_video.avi<br data-mce-bogus="1">

Ngalokhu sikwazile ukusuka ku-MKV kuya ku-AVI ukugcina i-codec efanayo eyayinefayela loqobo, ngoba sibeke ikhophi kuleyo nketho. Ukube besifuna ukuyiguqula, besingacacisa enye i-codec kusuka kuleyo etholakalayo (bona man ffmpeg). Futhi uma ufuna ukucacisela ama-codec afanayo noma ahlukile alalelwayo namavidiyo, ungabheka lezi zibonelo engikukhombisa zona:

ffmpeg -i nombre_video.mkv -vcodec copy -acodec copy nombre_video.avi
ffmpeg -i nombre_video.mkv -vcodec mpeg4 -acodec mp3 nombre_video.avi

La ukulahleka ngesikhathi sokuguqulwa kuzoba kuncane. Lapho inqubo isiqedile sizoba nefayela lethu le-AVI elenziwe enkombeni lapho sisebenza khona.

Ukuguqulwa nge-mencoder

Noma kunjalo i-mencoder iyithuluzi elihle, Ngikhetha i-ffmpeg, kepha ukunambitha imibala. Yingakho nami ngizochaza inqubo. Uma sekufakiwe, ngincoma ukuthi usebenzise i-mancoder ukubona konke ongakhetha kukho, ngoba njengokwedlule kunokhetho oluningi futhi kuyinkimbinkimbi impela. Kepha ukukunikeza isibonelo sokudlulisa i-MKV iye ku-AVI, umyalo wokukhipha ngu:

mencoder nombre_video.mkv -ovc xvid -oac mp3lame -lameopts abr:br=192 -xvidencopts pass=2:bitrate=-700000 -o nombre_video.avi

Njengoba ukwazi ukubona, nakhu esinakho kungezwe i-codec Ividiyo ye-Xvid, ne-MP3 yomsindo, nge-bitrate ethile, njengoba ubona kokukhethwa kukho ...

Ngiyethemba lesi sifundo sokuguqula phakathi kwe-MKV ne-AVI sikusizile, futhi uyazi, ungakhohlwa ukushiya ukuphawula kwakho, iziphakamiso, noma ukungabaza ...
