进入gstreamer-rgaconvert目录

gcc -fPIC -shared plugins/gstrgaconvert.c -o libgstrgaconvert.so -I plugins/ -lrga -lgstallocators-1.0 -lgstreamer-1.0 -lglib-2.0 -lgobject-2.0 -lgstbase-1.0 -lgstvideo-1.0 -lgstaudio-1.0 -I/usr/include/glib-2.0 -I/usr/include/gstreamer-1.0 -I /usr/lib/aarch64-linux-gnu/glib-2.0/include/

复制生成后的文件

cp libgstrgaconvert.so /usr/lib/aarch64-linux-gnu/gstreamer-1.0/

查看是否生效

gst-inspect-1.0 |grep rgaconvert

rgaconvert: rgaconvert: Rockchip rga hardware convert

如是生效了就如上所示
