slow convert by using AMF

Post by SirDrake » Sat May 11, 2019 10:12 am

hello,
i am using ffmpeg to convert movies from mpeg to mkv using ffmeg.
to speed up this i take usage of the graphisCard RX 550

.....-c:v h264_amf -usage transcoding -quality quality -profile main -rc cbr -level 3.1.....

all is fine until Radeon 18.6.1 by having a speed of 7-9

If i try to install a higher version, the speed of converting shrink dramaticly down lesser that 2

could be the reason the used AMF 1.4.7 Libarie within ffmpeg ?
is there any update planed ?

thanks for info
SD
