Ubuntu18.04 GPU加速

fire4529

请问如果要用gpu加速 相关的内核怎么整

用AIO-RK3399PRO-JD4-UBUNTU18.04-GPT-20190724-1038.img这个烧写的系统

另外：
在Ubuntu18.04下，用gst-launch-1.0，提示缺少库libMali_wayland.so

我找了下有libmali.so，但是没有这个库，找了下资料发现有个libmali的GitHub：
https://github.com/rockchip-linu ... b/aarch64-linux-gnu

我下载了进行安装
libmali-midgard-t86x-r18p0-wayland_1.9-1_arm64.deb

跑示例/usr/local/bin/h264enc.sh

rk3399pro要gpu加速要像这篇文章说的这样搞吗
