Приветствую!
Как бы включить аппаратную поддежку кодирования h264 на железке Nanopi neo core с ядром
# uname -a
Linux NanoPi-NEO-Core 4.14.111 #126 SMP Mon Feb 22 17:04:18 CST 2021 armv7l armv7l armv7l GNU/Linux
Скомпилил и установил ffmpeg с Cedrus H264 и cedar_ve.ko
# dmesg | grep cedar
[ 4.982170] cedar_ve: loading out-of-tree module taints kernel.

правлю /boot/sun8i-h3-nanopi-neo-core.dts
reserved-memory {

ranges;
cma@43c00000 {
compatible = "shared-dma-pool";
reusable;

};
};

};
теперь имеем

теперь правлю syscon

и все, больше железка не бутиться ((
