a demo shows that how to use rockchip mpp framework in linux

MPP_LINUX_C++

a demo shows that how to use mpp on linux if you want to using mpp on android,please use MediaCodec directly(hardware codec has been embedded in MediaCodec).

make & test

first please modify CMakeLists.txt to specified c and c++ compiler.
just do that
set(CMAKE_C_COMPILER "enter your toolchain gcc path)
set(CMAKE_CXX_coMPILER "enter your toolchain g++ path")

cmake version >= 2.8 is required
root:cd build
root:make
root:./mpp_linux_demo

how you will see

on your device screen,you will see that local avc file is displayed.

编译失败

请问一下如何编译测试？我在编译过程中就提示失败，用的rk3288，ubuntu16.04的系统

is it working in Tinker Board RK3288 ?

I built this with a few modifications on rk3288 board(Tinker OS)

Question.
It does not seem to work properly.
Does not work on the debian Tinker Board?

vpu.h not found

My chip is rk3399.
I set the CMAKE_C_COMPILER and CMAKE_CXX_COMPILER in CMakeList.txt.
Then I do mkdir build;cd build;cmake ..;make, and I get the following error.

root@norco:~/mpp_linux_cpp/build# make

Should I install a vpu.h manually? How to install it?

where is "build" dir ?

failed to open rga dev /dev/v4l/by-path/platform-ff680000.rga-video-index0

您好，我编译后运行报错找不到rga设备。我用的是RK3568，我看了一下，这个/dev/v4l/by-path路径下，只有下图的这几个设备：

但我发现存在/dev/rga，请问知道是怎么回事嘛
