DeepStream Python 应用程序

此存储库包含 Python 绑定和DeepStream SDK的示例应用程序。

支持的SDK版本：6.0

新：绑定源以及构建说明现在可以在绑定下获得！

从发布部分下载包含绑定和示例应用程序的最新发布包。

请在DeepStream SDK 论坛上报告任何问题或错误。这使 DeepStream 社区能够在中心位置寻求帮助。

Python 绑定

DeepStream 管道可以使用 Gst Python（GStreamer 框架的 Python 绑定）构建。为了访问 DeepStream 元数据，Python绑定作为此存储库的一部分提供。该模块是使用Pybind11生成的。

 

这些绑定支持元数据结构和函数的 Python 接口。HOW-TO 指南中记录了该接口的用法，并在示例应用程序中进行了演示

 

示例应用程序

此处提供的示例应用程序演示了如何使用 Python 处理 DeepStream 管道。
示例应用程序需要元数据绑定才能工作。

要运行示例应用程序或编写您自己的应用程序，请参阅HOW-TO 指南

应用程序下的每个应用程序的子目录中提供了详细的应用程序信息。

用 Python 编写 DeepStream 应用程序

本指南提供了使用 Python 进行 DeepStream 应用程序开发的资源。

• 先决条件
• 运行示例应用程序
• 管道建​​设
• 元数据访问
• 图像数据访问
• 自定义推理输出解析
• 常见问题解答和故障排除

先决条件

• Ubuntu 18.04
• DeepStream SDK 6.0或更高版本
• Python 3.6+
• Gst Python v1.14.5

Gst python 应该已经安装在 Jetson 上。
如果缺少，请按照以下步骤安装：(加sudo根据你的设备状态)

   $ sudo apt-get install python-gi-dev
   $ export GST_LIBS="-lgstreamer-1.0 -lgobject-2.0 -lglib-2.0"
   $ export GST_CFLAGS="-pthread -I/usr/include/gstreamer-1.0 -I/usr/include/glib-2.0 -I/usr/lib/x86_64-linux-gnu/glib-2.0/include"
   $ git clone https://github.com/GStreamer/gst-python.git
   $ cd gst-python
   $ git checkout 1a8f48a
   $ ./autogen.sh PYTHON=python3
   $ ./configure PYTHON=python3
   $ make
   $ sudo make install

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

  git checkout -b
