ffmpeg: Rekhoda idesktop yakho yeLinux ngaphandle kweengxaki

ffmpeg yingqokelela yezixhobo zesoftware zasimahla ezinokuthi phantse wonke umntu abe sele ezazi. Inguqulelo yamva nje ezinzileyo ibe yi-1.1, kwaye inokurekhoda, iguqule, isasaze iaudiyo nevidiyo, iqulethe codecnjl. Yenzelwe i-Linux kwasekuqaleni, nangona inokusetyenziswa kwezinye iinkqubo. Ngoku unokurekhoda idesktop yakho usebenzisa le pakethi kwaye ubonise abahlobo bakho izinto ezenzekayo okanye uzisebenzisele ukurekhoda izifundo zevidiyo.

Ngexesha elithile elidlulileyo ndakhangela izixhobo  ukurekhoda okwenzekileyo kwiscreen sam sekhompyuter ukwenza iividiyo zeLinux, emva kokukhangelwa okuninzi kunye nokuvavanywa, izixhobo endizifumeneyo khange zindivumele ukuvula i-OpenSuSE (ndigqibele ndihlala nerekhodimydesktop), endaweni yoBuntu ndiyifumene i-xvidcap.

Kulungile ke, Ndiza kuchaza into ukuze bangakhangeli kangako ukuba iyenzeka kubo njengoko isenza kum kwaye iinkqubo ezikhoyo zayo azikholosi. Imalunga nendlela yokwenza ngayo ngenxa yeffmpeg kunye nePulseAudioVolume Control. Ukuba unayo le mibekelelo mibini ifakiweyo (ffmpeg kunye ne-pavucontrol), into yokuqala kukuvula iPulseAudio Volume Control kwaye uye kwiscreen soku "Rekhoda", apho siza kukhetha ukhetho "Ukubeka iliso kwi-Audio AnalogStereo eyakhelweyo" yokurekhoda. Emva koko, ukuzenzekelayo inkqubo kwaye uyenze ngendlela elula, kufuneka sisebenzise iskripthi sisebenzisa omnye wale miyalelo ilandelayo (ebekwe kulawulo olufanayo apho ikhoyo):

         sh irekhoda yedesktop

         //rekodi yokurekhoda

         Isishicileli sedesktop somthombo

Kodwa kuqala kufuneka senze iskripthi ukuze senziwe. Ukwenza oku, sivula iphepha elibhaliweyo kunye nomhleli esiwufunayo kwaye siya kuyibiza ifayile "desktoprecording.sh" ngaphandle kwezicatshulwa kwaye ngaphakathi sibhala:

#! / bin / ibash

Ubunzima = "@"

IGAMA = "iividiyo.avi"

ukuba [$ STR]; emva koko

IGAMA = "$ @"

enye

"Ukuba awukhankanyi igama lefayile yevidiyo, kuya kusetyenziswa i-myivideo.avi"

IGAMA = "iividiyo.avi"

fi

#NAME = "$ (echo $ NAME | sed 's / \ / \\ / g')";

bhekisa "Kugcinwa kwi $ NAME ...";

ffmpeg –f alsa –i default -f x11grab –s ZZZZxxYYY –r RR –i: 0.0 –sameq “$ NAME”

Ukuba ujonga kumgca wokugqibela we elishicilelweNgomgaqo we-x11grab sinokurekhoda indawo eboniswe emva kwe -s (kufuneka ubeke endaweni yeZZZZxxYYY ngesisombululo okanye ubungakanani bendawo ofuna ukuyirekhoda, umzekelo 800 × 640). I-- r ukhetho lusivumela ukuba singene kwifreyimu ukuze ividiyo irekhodwe (iRR kufuneka ithathelwe indawo yile nto, umzekelo 30). Kwaye u-voila, emva kokugcina iskripthi ungaqala ukusisebenzisa.
