Toban bilood oo horumar ah ka dib, xirmada FFmpeg 4.4 multimedia ayaa diyaar ah, oo ay ku jiraan codsiyo iyo ururin maktabado loogu talagalay hawlgallada qaabab kala duwan oo warbaahin ah (duubista, beddelidda iyo dejinta qaab maqal iyo muuqaal ah). Xirmada waxaa lagu qaybiyaa shatiga LGPL iyo GPL, horumarinta FFmpeg waxaa lagu fuliyaa dhinaca mashruuca MPlayer.
