Ukufumanisa i-CLI: Ukusuka kwi-wma ukuya kwi-mp3 ngamanyathelo ama-2

Molweni kubo bonke abakhohlakeleyo nabathandi bemeko-bume GNU / Linux ukuba njengam, sichitha usuku sizama ukwenza into efanayo neyenziwa zezinye iinkqubo, ezinganyanzelekanga ukuba zibekho Windows. Kuyavela ukuba ndifumene iCD yamvanje X-Alphonse naphambi kwenani elikhulu leegeki phaya kwaye undazi, kufanelekile ukucacisa ukuba le CD bayinika kwiiyunivesithi kodwa kulungile kwinto ebiyiyo.

Zonke iingoma ezikwiCD zikwi WMA (IWindows Media Audio ... ubuncinci ndicinga ukuba mayibe sisichazi kwezo zinto) kwaye ngokubanzi sine-guataca (indlebe) ilungelelaniswe nefomathi MP3, ke ndaye ndagqiba kwelokuba ndifumanise ukuba ingaba ikhona na indlela, ngaphandle kokuwela kwifilosofi yesoftware yokufaka usetyenziso lwento inkqubo yethu ekwaziyo ukuyenza ngokwayo, ukufezekisa okufanayo kwaye ujonge ukuba kwenzeka njani…. inkqubo yam (I-Debian 6.0 kunye ne-LXDE)  Ndandisele ndikulungele ukuyenza, ndandingazi ...

Masibone ukuba ndiyazichaza na, isidlali sevidiyo endisithandayo umdlali. Enye into esiyifunayo sisixhobo seConsole esibizwa blade kodwa andazi ukuba yeyam Debian kodwa ndaya ukuyifaka…. voila yayisele ifakiwe kwaye andazi ukuba oku kungagqibekanga okanye akunjalo. Ngoku kuyaqhubeka, ukuba sele benayo umdlali y blade emva koko masiye kwindlela yokwenza, ukuba ngokuchaseneyo awunazo ezi zicelo kakuhle…. Ulinde ntoni ukuba uzifake? vula ikhonsoli njengengcambu kunye nohlobo (ucinga ukuba usebenzisa iDebian okanye enye yeziveliso zayo):

apt-get install mplayer lame

Silungile, sele sinezicelo esizifunayo esizifakileyo kwinkqubo yethu, nangona benditshilo, abanye sele bezisa ngokwakhona ukuze umlingo uqale:

Masicinge ukuba sinefolda apho iifayile zefomathi zeWMA esifuna ukuziguqula zikhona, ndikwenzile oku kuvavanyo, ke kwisikhombisi siza kubona into enje:

[ikhowudi] neji @ Maq2: ~ / Desktop / wmatomp3 $ ls
4.wma
[/ ikhowudi]

Inkqubo yokuqhwala ivumela ukuba siguqule ifayile ye-WAV kwifomathi ye-MP3 kodwa ekubeni esinayo yifayile yeWMA emva koko siya kusebenzisa iMplayer ukuyiguqulela kwi-WAV ngolu hlobo lulandelayo:

[ikhowudi] neji @ Maq2: ~ / Desktop / wmatomp3 $ mplayer 4.wma -ao pcm
I-MPlayer SVN-r31918 (C) 2000-2010 Iqela le MPlayer
Awunakho ukuvula isixhobo sokugcoba / i-dev / igalelo / i-js0: Akukho fayile okanye umkhombandlela
Ayikwazi ukufaka i-joystick yokufaka
mplayer: ayinakunxibelelana nesokethi
mplayer: Akukho fayile okanye umkhombandlela unjalo
Ayiphumelelanga ukuvula inkxaso ye-LIRC. Awuyi kuba nakho ukusebenzisa ulawulo lwakho olukude.

Ifomathi yefayile yomsindo ifunyenwe kuphela.

Ungakhathazeki ukuba ifayile ebizwa «zandiodube.wav»Ngaphandle kwezicatshulwa, leyo yifayile eguqulweyo umdlali kwaye ngoku siza kuyisebenzisa kunye nenye inkqubo ukuyiguqula ibe yifomathi yeMP3:

[ikhowudi] neji @ Maq2: ~ / Desktop / wmatomp3 $ lame -r3mix audiodump.wav 4.mp3

Ukwenza iikhowudi kwi-audiodump.wav ukuya kwi-4

Ilungile…. mibini kuphela imiyalelo kwaye sele siguqule ifayile ukusuka kwi-WMA ukuya kwi-MP2. Ndiyazi ukuba kwabaninzi akumnandi ukusebenzisa imiyalelo emininzi kodwa ungasoloko usenza iSkripthi ukuba siqhubeke kwaye sisebenze ngokufanayo kulawulo lweefayile lonke.

Okwangoku ndizokugqibezela ngale nto, uyazi, ube ulungile kwaye ungalahli umdla wokufunda kunye nokunye okubaluleke ngakumbi: emva kokuba ufunde into nokuba ingabonakala ingabalulekanga kangako, sukuyeka ukwabelana ngayo nabanye njengokuba ndenzile kuwe .
