如何在RV1126上进行视频/图像处理处理速度提升呢

用 rga 加速处理

cmake编译rga的时候出现以下问题
我已经按照linux-rga里的README修改了buildroot.cmake里的以下配置
1. 指定TOOLCHAIN_HOME为交叉编译工具的路径
2. 指定CMAKE_C_COMPILER为gcc编译命令的路径
3. 指定CMAKE_CXX_COMPILER为g++编译命令的路径

请问这个问题有什么解决方法吗？

default to Release build for GCC builds
RGA is compiling with cmake

make: *** 没有指明目标并且找不到 makefile。 停止。

不是使用cmake直接编译的，是在buildroot系统里面添加rga配置编译。直接编译会找不到库文件

请问1126如何接入视频进行检测？
