RK3566 MPPJPEG 编码初入门 mpi_enc_test

一、导览

本文介绍了使用rk mpp 库的demo 程序，对一帧 nv12的yuv 图像进行jpeg 编码，最后输出jpeg图像的过程。作为学习mpp 入门的教程。
rk mpp 的源码仓库地址是：https://github.com/rockchip-linux/mpp/
参考文档在：https://github.com/rockchip-linux/mpp/blob/develop/doc/Rockchip_Developer_Guide_MPP_CN.md

二、编译程序

下载源码后，mpp 框架是使用CMake 进行编译的，首先需要配置好交叉编译工具，我是在linux 平台，aarch64 架构下使用的，所以编辑 mpp/build/linux/aarch64/arm.linux.cross.cmake
将CMAKE_C_COMPILER、CMAKE_CXX_COMPILER 设置成项目所使用的工具链
在这里插入图片描述
然后执行 make-Makefiles.bash ，将自动调用cmake 生成makefile 文件，最后直接make 就能编译整个mpp 以及demo

编译生成的文件如下：

librockchip_mpp.so:mpp的运行时动态库
test/* :test 目录下存放所有的demo app

三、执行

首先将librockchip_mpp.so 添加到链接路径，准备好一张yuv图像，以及mpi_enc_test 程序

# 将ov5648.yuv 编码成jpeg图像，-t 表示编码类型为jpeg
root@RK356X:/mnt/nfs/output# ./mpi_enc_test -w 800 -h 600 -t 8 -i ./ov5648.yuv -o tmp.jpeg

demo输出的log需要通过 /var/sys/message 查看：

Dec  9 03:02:08 RK356X user.info mpp[392]: mpi_enc_test: ./mpi_enc_test average frame rate 89.27

可以看到编码了一帧图像，耗时11ms+6ms

直接运行/mpi_enc_test可以打印help信息：
