Python bindings for DeepStream Metadata libraries These bindings are provided as a compiled module, available for x86_64 and Jetson platforms. Find them at: bindings |- x86_64 | |- pyds.so |- jetson |- pyds.so 2. DeepStream test apps in Python Four test apps are available: deepstream-test1/deepstream_test_1.py deepstream-test2/deepstream_test_2.py deepstream-test3/deepstream_test_3.py deepstream-test3/deepstream_test_4.py -------------------------------------------------------------------------------- Installing Pre-requisites: -------------------------------------------------------------------------------- DeepStream SDK 4.0.1 -------------------- Download and install from https://developer.nvidia.com/deepstream-download Python 3 ---------- Should be already installed with Ubuntu 18.04 Gst-python ---------- Should be already installed on Jetson If missing, install with the following steps: $ 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 -------------------------------------------------------------------------------- Running the samples -------------------------------------------------------------------------------- The apps are configured to work from inside the DeepStream SDK 4.0.1 installation. Untar the contents into <DeepStream install root>/sources/. Note that the apps import the pyds module from this relative path: ../bindings/<platform> Follow README in each app's directory to run the app. Example: running test1 app: $ cd deepstream-test1 $ python3 deepstream_test_1.py <input .h264 file> -------------------------------------------------------------------------------- Notes: -------------------------------------------------------------------------------- As with DeepStream SDK, if the application runs into errors, cannot create gst elements, try again after removing gstreamer cache rm ${HOME}/.cache/gstreamer-1.0/registry.x86_64.bin
