替换nvoverlaysink为nvdrmvideosink或nv3dsink
重新编译
Jetson Deepstream-app如果不能满足需求，只能修改并重新编译
安装json-glib
fatal error: json-glib/json-glib.h: No such file or directory
27 | #include <json-glib/json-glib.h>
如果缺少json-glib，使用如下办法解决
sudo apt-get update && sudo apt-get install meson ninja-build
git clone https://github.com/ebassi/json-glib
cd json-glib
mkdir _build && meson _build .
ninja -C _build
ninja -C _build test
ninja -C _build install
