请问这是什么问题呢
# ./mpi_dec_test -t 7 -i /userdata/ss.h264 -n 10
mpp[3829]: mpi_dec_utils: cmd pa ...

apt install一下chrpath，然后用chrpath命令修改依赖的库路径，让你自己编译的mpi_dec_test命令使用系统自带的librockchip_mpp库：

linaro@linaro-alip:~/workspace/git/mpp/mybuild$ chrpath -l ./test/mpi_dec_test
./test/mpi_dec_test: RUNPATH=/home/desktopclient/workspace/git/mpp/mybuild/mpp:

linaro@linaro-alip:~/workspace/git/mpp/mybuild$ chrpath -r /usr/lib/aarch64-linux-gnu ./test/mpi_dec_test
./test/mpi_dec_test: RUNPATH=/home/desktopclient/workspace/git/mpp/mybuild/mpp:
./test/mpi_dec_test: new RUNPATH: /usr/lib/aarch64-linux-gnu

linaro@linaro-alip:~/workspace/git/mpp/mybuild$ ldd ./test/mpi_dec_test | grep librockchip_mpp
    librockchip_mpp.so.1 => /usr/lib/aarch64-linux-gnu/librockchip_mpp.so.1 (0x0000007fab4b4000)

然后再执行这个自行编译的mpi_dec_test命令，就ok了。
