FFmpeg ndiyo inotungamira multimedia chimiro
FFmpeg 7.0 "Dijkstra" yakatoburitswa uye mune iyi vhezheni itsva Mutsara wekuvandudzwa kwakakosha unoratidzwa kubva pakuvandudza kuenderana nemafomati akasiyana, pamwe nekuunzwa kwezvitsva zvinoshanda, kuvandudzwa kwemaencoder, decoder, kugadzirisa kwebug nezvimwe.
Muiyi vhezheni nyowani yeFFmpeg 7.0 inoratidzwa, chimwe chezvinhu zvinonyanya kuzivikanwa maficha ndeye kushandiswa kweparallel execution yemabasa, izvi zvinokutendera kuti uite mabasa akawanda panguva imwe chete, senge kuburitsa / kurongedza midhiya midziyo, decoding, encoding, uye kushandisa mafirita.
Imwe yekuvandudzwa kwakaratidzwa muFFmpeg 7.0 ndiko kuenderana nemafomati, uye inosimbisa iyo kuunzwa kwerutsigiro rwevhidhiyo encoding uye decoding muMPEG-5 fomati (EVC - Yakakosha Vhidhiyo Coding) kuburikidza neyekunze raibhurari libxevd.
Uye zvakare, ivo vakawedzerwa midhiya mudziyo unpackers uye mapaketi emafomati seQOA (Quite OK Audio) iyi fomati inoshandiswa kutumira odhiyo pasina kurasikirwa kwemhando uye inomira kunze kwekuita kwayo kwepamusoro zvichienzaniswa nemamwe mafomati, kubvira. Inonzi inokurumidza katatu kupfuura Ogg-Vorbis decoding.
Iyo Yakawedzera tsigiro ye unpackers uye mapaketi eiyo IAMF fomati (Immersive Audio Model uye Format). Iyi fomati yakagadzirirwa kugovera yakatenderedza ruzha zvinobudirira, ichipa mudziyo unosanganisira rumwe ruzivo rwakakosha pakushanda kwealgorithms inovakazve nhanho dzekurira uye kuita musanganiswa wekurira.
Kune rimwe divi, FFmpeg 7.0 inosanganisira decoder yekuedza yemhando yeVVC (Versatile Video Coding), inozivikanwawo seH.266. Iyi decoder nyowani inomiririra kufambira mberi mukukwanisa kweFFmpeg kubata chizvarwa chinotevera kudzvanya kwevhidhiyo, kufambisa kutambwa uye kushandura zvirimo mukugadzirisa kubva kuSD kusvika ku8K, nerutsigiro rweHDR (High Dynamic Range) uye vhidhiyo yakakura mu360 madhigirii.
Pamusoro pekuvandudzwa uku mukuenderana uye kushanda, muFFmpeg 7.0 Iko kugona kushandisa D3D12VA API kwaitwa (Yakananga 3D 12 Vhidhiyo Encoding) yehardware kukwidziridza decoding yemafomati akasiyana seH264, HEVC, VP9, AV1, MPEG-2 uye VC1, kuvandudza mashandiro uye kugona mumasisitimu anoenderana neiyi tekinoroji.
Yeimwe shanduko izvo zvinomira pachena:
- Ikozvino inotsigira Hardware yakamhanyisa decoding uchishandisa Vulkan uye libplacebo APIs.
- Yakawedzerwa rutsigiro rwezvirimo URI protocol inoshandiswa papuratifomu yeAroid.
- Kuvaka zvinodiwa zvawedzera; A compiler inotsigira C11 standard yava kudiwa kuunganidza FFmpeg.
- YeQSV (Intel Quick Sync Vhidhiyo) yakavakirwa encoders, iyo yakasarudzika bitti yekudzora nzira yakashandurwa kubva kuVBR kuenda kuCQP.
- Iyo itsva unpacker yeDVD-Vhidhiyo midhiya midziyo yakaunzwa, zvichibva pane libdvdnav uye libdvdread raibhurari kubva kuVideoLAN chirongwa.
- Izvozvi zvinogoneka kuendesa metadata mumapaketi mune iyo flv fomati yekushandiswa.
- Yakawedzera DXV DXT1 encoder uye LEAD MCMP decoder.
- Kune MP4 uye ISOBMFF mafomati, kuisirwa kweA AVE metadata kwaitwa.
- Tsigiro yeAFGS1 tekinoroji, inoshandiswa muAV1 Firimu Grain kududzirwa, yakawedzerwa kuvandudza kudzvanywa kwemifananidzo yegorosi.
- Yakawedzera rutsigiro rwemifananidzo ichiri muHEIF neAVIF mafomati, pamwe nemataira achiri mifananidzo.
- Dolby Vision mbiri yave kuwanikwa yeAV1 fomati.
- Chekupedzisira, rutsigiro rwunopihwa kuendesa mberi HDR10 metadata paunenge uchikodha kuburikidza neiyo libx264, libx265, uye libsvtav1 maraibhurari.
Kune avo vanofarira kudzidza zvakawanda nezve kuburitswa kutsva uku kana kudzidza zvakawanda nezveFFmpeg, unogona kubvunza iwo ruzivo Mune inotevera chinongedzo.
Dhawunirodha uye tora FFmpeg 7.0
Pakupedzisira, pKune avo vanoda kuisa kana kugadzirisa FFmpeg 7.0 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:
sudo pacman -S ffmpeg
