Rekhoda idesktop yakho kwisiphelo sendlela kunye neFFmpeg

Kwiiyure ezimbalwa ezidlulileyo sipapashe Inqaku apho sichaze khona ukuba ungayiguqula njani ifayile yeaudiyo kwenye ifomathi (kunye nesandi) ngeFFmpeg. Kwelo nqaku sichaze nokuba isakhelo ekuthethwa ngaso sisixhobo esinamandla esinokwenza ngaso imisebenzi emininzi enxulumene nevidiyo kunye nevidiyo, kwaye ngelinye ixesha siya kukufundisa Ungayibhala njani ikhusi lePC yethu ngeFFmpeg ukusuka kwisiphelo sendlela. Lo mzuzu ufikile kwaye inqaku liya kuba yile.

Rekhoda isikrini kunye nale sikhokelo izakuba nzima ngakumbi kunokuguqula iaudiyo. Ubunzima bufumaneka ngexesha lokubhalwa komyalelo, kuba into ekufuneka siyikhumbule ingaphezulu kokubeka umyalelo, "-i" kunye neefayile ezimbini, igalelo kunye nemveliso. Ukongeza, indlela yokwenza yenziwe yahlaziywa kuba baguqule umyalelo / isixhobo esiza kurekhoda ngaso isikrini. Ngaphandle kokuqhubela phambili, ngoku siza kuchaza amanyathelo anokulandelwa, ekungekho amanye ngaphandle kwalawo afunyenwe kwifayile ye- iphepha elisemthethweni yeprojekthi.

I-FFmpeg isivumela ukuba sibhale phantsi iscreen sedesktop kunye nangaphandle kwesandi

Njengezinye iinkqubo ezinje nge-VLC okanye i-SimpleScreenRecorder, i-FFmpeg isivumela ukuba sibhale phantsi iscreen sedesktop kunye nangaphandle komsindo. Ukongeza, iya kuthi isivumele ukurekhoda kuphela isahlulo sedesktop yethu, into eya kuba lula ukusebenzisa usetyenziso olunonxibelelwano lomsebenzisi olunokusivumela ukuba sikhethe ummandla oza kurekhoda ngesikhombisi. Ngayiphi na imeko, imiyalelo okanye amanyathelo ekufuneka elandelwe ukurekhoda isikrini sedesktop yethu iya kuba koku kulandelayo:

1. Njengokuba siguqula iifayile, siyaqinisekisa ukuba sinesoftware eyimfuneko efakiweyo. Ukwenza oku, chwetheza "ffmpeg" (ngaphandle kwezicatshulwa) kwisiphelo sendlela. Siza kubona into efana nale ilandelayo:
2. Ukuba kukho into enje apha ngasentla ibonakala, siya kwinyathelo lesi-3. Ukuba akunjalo, sibhala oku kulandelayo kwisiphelo sendlela:

sudo apt install ffmpeg

3. Xa isoftware ifakiwe, kuya kubakho amanyathelo amabini kuphela aseleyo: qala ukurekhoda kwaye uyeke. Ukuyiqala, siza kubhala lo myalelo ulandelayo.

ffmpeg -video_size 1920x1080 -framerate 25 -f x11grab -i :0.0 salida.mp4

• Ukusuka ngasentla kufuneka kuthathelwe ingqalelo:
  • 1920 × 1080 ubungakanani bokurekhodwa.
  • umgangatho wefreyimu linani lezakhelo ngomzuzu.
  • 0.0 ngummandla oza kuwurekhoda. Unokunika ukuqala kwe-X kunye ne-Y ukurekhoda inxenye yesikrini emva kwesimboli sokudibanisa, esinokubonakala ngathi 0.0 + 100,200 ngefestile eqala kwinqanaba X = 100 kunye nenqaku Y = 200.
  • iziphumo.mp4 yifayile yemveliso. Ukuba siyibeka ngokomyalelo odlulileyo, ifayile iya kugcinwa kwifolda yethu enegama "imveliso.mp4".

4. Okokugqibela, ukuyeka ukurekhoda sicinezela Ctrl + C

Rekhoda isikrini ngesandi

Ukuba into esiyifunayo kukurekhoda kwakhona iaudiyo, imiyalelo inokujongeka ngoluhlobo:

• Ukukhupha iAudio:

ffmpeg -video_size 1920x1080 -framerate 25 -f x11grab -i :0.0 -f pulse -ac 2 -i default salida.mkv

• Kwi-ALSA:

ffmpeg -video_size 1920x1080 -framerate 25 -f x11grab -i :0.0 -f alsa -ac 2 -i hw:0 salida.mkv

Ukuphucula umgangatho wezandi, kungcono ukuvala zonke iinkqubo ezingeyomfuneko. Kuzo zombini iimeko, for Yeka ukurekhoda ctrl + C. Xa sisenza oku, ividiyo izakusilinda kwifolda yethu enegama esililungiselele lona, ​​kwezi meko "output.mp4" okanye "output.mkv".

Kukho oko thatha ingqalelo ubungakanani bevidiyo. Kwimiyalelo, ndibeke "1920 × 1080" kuba bubungakanani kunye nokusonjululwa kwescreen sam. Into elungileyo kukuba nganye nganye yongeza ubungakanani / isisombululo sayo apho. Kuya kufuneka sazi ukuba ayifanelekanga ukwenza iskripthi sokumisela iodolo, kuba inokungaphumeleli okanye, kwiimeko ezintle, singabenza nzima ubomi bethu ngalo mzuzu sifuna ukuyeka ukurekhoda. Ukuba uthatha isigqibo sokuvavanya ukuba isebenza kakuhle kuwe ngeskripthi, ungasoloko uzama ukumisa inkqubo ngomyalelo "wemisebenzi", njengoko kuchaziwe Oku kubhaliwe ngoJuni ophelileyo.

Ucinga ntoni ngale ndlela yokurekhoda isikrini kwisiphelo sendlela kunye neFFmpeg?
