Description
thank you for good apps.
isn't memory released when using core image filter of ffmpeg?
as the below logs, used memory increase extremely (see VSZ, RSS, and %MEM in the below logs and man ps) and a swapfile generates. after it, ffmpeg is killed by system, as the below logs.
i can't think it is normal.
