基于deepstream-test3添加目标跟踪插件和4类sinkType输出(包括rtsp输入输出)
deepstream官方示例没有给出一个单管道的多类输入和4类sinkType输出的简单示例,于是,本人参考了一些资料之后,在deepstream-test3的基础上简单修改了一下,主要是为了增加目标跟踪的插件,file文件和rtsp的输出。
运行环境
- gpu服务器:可以使用官方提供的docker镜像,创建并进入docker容器里面编译运行
- jetson设备:jetson设备安装了deepstream的开发环境之后,直接编译运行
编译运行指令
-
解压文件:
tar -zxf deepstream-test3-zyh.tar.gz
cd deepstream-test3-zyh/ -
编译:
make clean
make -j4 -
运行:
./deepstream-test3-app rtsp://xxxx
或者
./deepstream-test3-app file:/home/xxx/test.mp4
代码
- deepstream_test3_app.c
