FFmpeg ndiyo inotungamira multimedia chimiro
The kuburitswa kweshanduro nyowani yeFFmpeg 6.1 codenamed "Heaviside", iyo yakange yakanonoka kweinenge hafu yegore nekuda kwekuita nguva dzose munzvimbo inochengeterwa, asi iri pano uye ichisvika. kuita kuwandudzwa kwerutsigiro nezvimwe zvakawanda.
Kune avo vasina kujairana neFFmpeg vanofanira kuziva kuti izvi ndizvo yemahara software chirongwa Iyo inogona iyo inobvumidza vashandisi kusarudza, encode, transcode, mux, demux, kuyerera, kusefa, kutenderera odhiyo uye vhidhiyo, pakati pezvimwe zvinhu zvakawanda zvimwe.
Main nyowani maficha eFFmpeg 6.1
Mune iyi vhezheni itsva inounzwa, inosimbiswa kuti iyo kugona kushandisa iyo Vulkan API ku Hardware vhidhiyo decoding mumafomati H264, HEVC uye AV1.
Pamusoro peizvi, muFFmpeg 6.1 a g yakawedzerwarutsigiro rutsva rwakawanda, ndizvo zvakaita nyaya itsva VAAPI yakavakirwa AV1 vhidhiyo fomati encoder, pamwe nekutsigirwa kwekushandiswa kwe HEVC, VP9 uye AV1 macodecs muhova zvichienderana ne rtmp protocol uye muflv fomati mafaera uye rutsigiro rwakawedzerwa rweVAAPI paWindows system ine libva-win32 library.
Zvakare muFFmpeg 6.1 iyo kugona kushandisa ma parameter kuti akurumidze encoding vhidhiyo uchishandisa raibhurari libx264, Yakawedzera tsigiro yekuraira kune seti uye asetts mafirita uye yakawedzera rutsigiro rweMicrosoft RLE fomati vhidhiyo encoder.
Dzimwe shanduko dzinomira pachena kubva mukuburitswa uku ndidzo sarudzo itsva dzakawedzerwa, mumwe wavo ari "-readrate_initial_burst" iyo yakawedzerwa kuseta yekutanga kuverenga nguva yekubhavha, mushure mezvo "-readrate" muganhu unotanga kushanda.
Imwe ndeye muffprobe, uko "-output_format" yakawedzerwa, iyo yakafanana ne "-ye" sarudzo uye inogona kushandiswa kuona iyo yakabuda fomati (semuenzaniso unogona kushandisa json fomati). Iyo XML yekubuda schema yakagadziridzwa kuti itsigire zvinhu zvakawanda zvakabatana nechinhu chemubereki mumwe.
Yeimwe shanduko izvo zvinoratidzika kubva pane iyi nyowani vhezheni:
- Iyo '-yepamusoro' sarudzo yadzikiswa uye setfield sefa inofanirwa kushandiswa pachinzvimbo.
- Iyo ARIB STD-B24 subtitle decoder inoitwa zvichibva pane libaribcaption raibhurari.
- Yakawedzera parser, encoder uye decoder yemidziyo midhiya muEVC fomati.
- Masefa evhidhiyo matsva:
color_vulkan-Inogadzira furemu yeruvara rwakapihwa nekudaidza iyo Vulkan API.
bwdif_vulkan: inoita deinterlacing uchishandisa iyo BWDIF algorithm inoshandiswa kuburikidza neVulkan API.
bwdif_cuda: deinterlacing uchishandisa iyo BWDIF algorithm, inoshandiswa zvichienderana neCUDA API.
nlmeans_vulkan: denoising uchishandisa isiri-yenzvimbo nzira algorithm inoshandiswa uchishandisa Vulkan API.
xfade_vulkan: Kuitwa kweiyo fade mhedzisiro uchishandisa iyo Vulkan API.
Zoneplate-Inogadzira vhidhiyo yekuyedza tafura yakavakirwa paFresnel zone board - Masefa matsva eruzha:
arls: inoshandisa inodzokororwa madiki masikweya kuenzanisa maparamita eimwe yekuteerana kwekuteerera kune imwe.
afireqsrc: inogadzira FIR (inogumira impulse mhinduro sefa) yakaenzana.
apsnr: inoyera mwero wechiratidzo-kune-ruzha.
asisdr: inoyera mwero wekukanganiswa kwechiratidzo.
Kune avo vanofarira kukwanisa kudzidza zvakawanda nezve kuburitswa kutsva uku kana kudzidza zvakawanda nezve FFmpeg, vanogona kubvunza ruzivo mune inotevera chinongedzo.
Dhawunirodha uye tora FFmpeg 6.1
Pakupedzisira, pKune avo vanoda kuisa kana kugadzirisa FFmpeg 6.1 Iwe unofanirwa kuziva kuti pasuru iyi inowanikwa mune dzakawanda Linux kugoverwa kana kana uchida, unogona kudhawunirodha kwaro kodhi kodhi yekubatanidza. kubva pane iyi link iripazasi.
Uye kuita kuisirwa kubva kune kodhi kodhi, zvakakwana kuita iyo yatove inozivikanwa script:
./configure make make install
Munyaya yeavo vari vashandisi veUbuntu, Debian kana chero chimwe chinobva kune izvi kugovera, ingovhura terminal uye ita unotevera kuraira mairi:
sudo apt install ffmpeg
Ndichiri panyaya yeFedora, murairo wekuita ndeuyu unotevera:
sudo dnf install ffmpeg
Uye kune avo vari vashandisi veArch Linux, Manjaro kana chero imwe inotorwa kubva kuArch Linux, zvakakwana kuita murairo unotevera:
