gst python

安装gst-python的步骤如下所示:
首先，需要安装python3的基础包，以避免在安装gst-python时出现找不到头文件的错误。可以运行以下命令进行安装：
sudo apt-get install python3-dev libpython3-dev

然后，需要安装python-gi-dev，并设置一些环境变量。可以运行以下命令进行安装和设置：
sudo apt-get install python-gi-dev
export GST_LIBS="-lgstreamer-1.0 -lgobject-2.0 -lglib-2.0" # 如果是x86_64系统，将aarch64替换为相应的架构
export GST_CFLAGS="-pthread -I/usr/include/gstreamer-1.0 -I/usr/include/glib-2.0 -I/usr/lib/aarch64-linux-gnu/glib-2.0/include"

接下来，需要克隆并编译安装gst-python。可以运行以下命令进行克隆、编译和安装：
git clone https://github.com/GStreamer/gst-python.git
cd gst-python
git checkout 1a8f48a # 根据版本有所不同
./autogen.sh PYTHON=python3
./configure PYTHON=python3
make
sudo make install

此外，如果需要下载deepstream的python文件并安装python bindings，可以按照以下步骤进行操作：
首先，安装基础依赖。可以运行以下命令进行安装：
apt install -y git python-dev python3 python3-pip python3.6-dev python3.8-dev cmake g build-essential \
libglib2.0-dev libglib2.0-dev-bin python-gi-dev libtool m4 autoconf automake libgirepository1.0-dev libcairo2-dev

然后，初始化子模型。可以运行以下命令进行初始化：
cd /opt/nvidia/deepstream/deepstream/sources/deepstream_python_apps/
git submodule update --init

最后，安装gst-python。可以运行以下命令进行更新证书和安装：
sudo apt-get install -y apt-transport-https ca-certificates -y sudo update-ca-certificates
cd 3rdparty/gst-python/
./autogen.sh
make
sudo make install

这样，你就成功安装了gst-python。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
