Ukukhutshwa kwephakheji yemultimedia yeFFmpeg 4.3 ngenkxaso ye-API yemizobo yeVulkan

Emva kweenyanga ezilishumi zophuhliso iyafumaneka iphakheji yemultimedia I-FFmpeg 4.3, equka isethi yezicelo kunye nengqokelela yamathala eencwadi okusebenza kwiifomathi ezahlukeneyo zemultimedia (ukurekhoda, ukuguqula kunye nokuguqula iifomati zeaudio kunye nevidiyo). Iphakheji isasazwa phantsi kwe-LGPL kunye neelayisensi ze-GPL, uphuhliso lweFFmpeg lwenziwa kufuphi neprojekthi. MPlayer.
