5 months ago 我是这样解决的，倒是编译通过了
ln -s /usr/local/lib/librockchip_mpp.so /usr/local/lib/libmpp.so
ln -s /usr/local/lib/librockchip_vpu.so /usr/local/lib/libvpu.so记得在/etc/profile中添加环境变量:
export CPLUS_INCLUDE_PATH=/usr/local/include/rockchip/:$CPLUS_INCLUDE_PATH
export PATH=/usr/local/lib/:$PATH
libmpp ? rk3588\external\mpp ，Official mpp code is compiled without libmpp，only libmpp_rc.a libmpp_codec.a libmpp_base.a ...
