Chokwadi unoziva kuti kune akati wandei marudzi e mafaira masisitimu kana FS (File System muChirungu). Zvimwe zvinovakirwa paFUSE (Filesystem muVashandisi nzvimbo), Linux kernel module iyo inobvumidza musina-ropafadzo mushandisi kuti agadzire yavo yavo yavo faira faira vasina kugadzirisa kernel kodhi.
Izvi zvinoitwa nekuda kweiyi "bhiriji" kuitisa kuti vakwanise kuve nemahurongwa Virtual FS (ona VFS), izvo zvakasiyana nedzetsika, usachengete yavo data. Ivo vanongoita senge yepakati rukoko zvakada kutaurwa vasina kupinda mune zvakawandisa ruzivo.
Izvo zvakati, pamwe iwe zvakare unoziva vane simba ffmpeg chishandiso, yezvinhu zvemultimedia kugadzirisa, kugadzirisa, uye kuchinja mafomati emafaira, pakati pezvimwe zvinhu. Chishandiso chine simba icho chatakatonyora nezvacho mune ino blog. Zvakanaka, ikozvino kujoina ese maviri mazano isu tine ffmpegfs.
Chii chinonzi ffmpegfs? Zvakanaka, iri FUSE-yakavakirwa faira sisitimu ye-pa-iyo-inobhururuka vhidhiyo uye odhiyo transcoding ichivhurwa. Chinhu chakanakisa chinoshanda uye chinonakidza.
ari ffmpegfs inosimbisa Ndizvo:
- Kudhindisa verenga-chete. Ndokunge, chinja odhiyo uye vhidhiyo mafomati pane nhunzi.
- Kusununguka, uye iwe unogona kuona iro peji mu Github.
- Inotsigira mafomu senge MP4, WebM, OGG, MP3, OPUS, MOV, ProRes, WaV, nezvimwe.
- Yakanyorwa mukati C uye C ++, kushandisa raibhurari yeFUSE.
Nekuiswa kwayo, unogona kuzviita kubva pazororo rako raunofarira distro, senge neAPT-GET muDebian uye zvigadzirwa. Kamwe yaiswa, unogona kuishandisa nyore nyore. Semuenzaniso, fungidzira iwe uchida chinja mafaera ese kubva kudhairekitori / imba / multimedia kuenda kuMOV uye kuendesa kune / kumba / kushandurwa, ipapo unogona kushandisa unotevera kuraira:
ffmpegfs --desttype=mov+aiff --log_maxlevel=DEBUG --cachepath=/tmp/cache ~/home/multimedia ~/home/convertidos
Kana iwe unogona chinja zvese odhiyo kubva kune imwechete dhairekitori kune MP3 ine 256 Bitrate:
ffmpegfs --audiobitrate=256K --desttype=mp3 ~/home/multimedia ~/home/convertidos -o allow_other,ro
Sezvauri kuona, zviri nyore kushandisa ...
