Pambuyo pa miyezi isanu ndi umodzi yachitukuko, phukusi la FFmpeg 5.1 la multimedia likupezeka, lomwe limaphatikizapo mndandanda wa mapulogalamu ndi mabuku osungiramo mabuku ogwiritsira ntchito pamitundu yosiyanasiyana ya multimedia (kujambula, kutembenuza ndi kulembera ma audio ndi makanema). Phukusili limagawidwa pansi pa layisensi ya LGPL ndi GPL, chitukuko cha FFmpeg chikuchitika moyandikana ndi polojekiti ya MPlayer. Kusintha kwakukulu kwa chiwerengero cha mtundu ndi chifukwa cha kusintha kwakukulu kwa API ndi kusintha kwa ndondomeko yatsopano yotulutsidwa, malinga ndi zomwe zatsopano zatsopano zidzapangidwira kamodzi pachaka, ndi kumasulidwa ndi nthawi yowonjezera yothandizira - kamodzi pazaka ziwiri zilizonse. FFmpeg 5.0 idzakhala yoyamba LTS kutulutsidwa kwa polojekitiyi.
Zina mwazosintha zomwe zawonjezeredwa mu FFmpeg 5.1 zikuphatikiza:
- Thandizo lowonjezera pamafayilo amtundu wa IPFS ndi ndondomeko yomwe imagwiritsidwa ntchito nayo pomanga ma adilesi okhazikika a IPNS.
- Thandizo lowonjezera la mtundu wa zithunzi za QOI.
- Thandizo lowonjezera la mawonekedwe azithunzi za PHM (Portable Half float Map).
- Yakhazikitsa kuthekera kogwiritsa ntchito VDPAU (Video Decode and Presentation) API kuti hardware ifulumizitse kutsitsa makanema mumtundu wa AV1.
- Thandizo la mawonekedwe a cholowa cha hardware video decoding XvMC wagwetsedwa.
- Chowonjezera "-o" ku ffprobe utility kuti mutulutse ku fayilo yotchulidwa m'malo motulutsa mulingo.
- Onjezani ma decoder atsopano: DFPWM, Vizrt Binary Image.
- Onjezani ma encoder atsopano: pcm-bluray, DFPWM, Vizrt Binary Image.
- Zowonjezera zonyamula media (muxer): DFPWM.
- Owonjezera media chidebe unpackers (demuxer): DFPWM.
- Zosefera zatsopano zamavidiyo:
- SITI - kuwerengetsa mawonekedwe amtundu wa kanema SI (Spatial Info) ndi TI (Temporal Info).
- avsynctest - Imafufuza zomvera ndi makanema.
- mayankho - kulondolera mafelemu odulidwa kupita ku fyuluta ina ndikuphatikiza zotsatira ndi kanema woyambirira.
- pixelize - imapanga pixelization ya kanema.
- colormap - chiwonetsero chamitundu kuchokera kumavidiyo ena.
- colorchart - kupanga tebulo la zoikamo zamitundu.
- chulukitsani - chulukitsani ma pixel kuchokera pa kanema woyamba ndi ma pixel a kanema wachiwiri.
- pgs_frame_merge imaphatikiza magawo ang'onoang'ono a PGS kukhala phukusi limodzi (bitstream).
- blurdetect - imatsimikizira kusokonezeka kwa mafelemu.
- remap_opencl - Amapanganso ma pixel.
- chromakey_cuda ndikukhazikitsa kwa chromakey komwe kumagwiritsa ntchito CUDA API kuti ifulumire.
- Zosefera zatsopano zamawu:
- kukambirana - kutulutsa mawu ozungulira (3.0) kuchokera ku stereo, ndikusunthira ku njira yapakati yamawu omveka a mawu omwe amapezeka mumayendedwe onse a stereo.
- tiltshelf - onjezerani / chepetsa ma frequency apamwamba kapena otsika.
- virtualbass - imapanga njira yowonjezera ya bass kutengera deta kuchokera kumayendedwe a stereo.
