1Donload dlstreamer docker:

推荐方式 启用ubuntu20.04docker环境 运行docker （https://hub.docker.com/r/intel/dlstreamer/tags ）并挂载代码目录。 [2022.1.0-ubuntu20-devel]测试可用

2Download the models from Open Model Zoo

python3 -m pip install --upgrade pip python3 -m pip install openvino-dev[onnx] /opt/intel/dlstreamer/samples/download_models.sh

models location:/home/dlstreamer/intel/dl_streamer/models/

3build:

1. dowload dlstreamer https://github.com/dlstreamer/dlstreamer tag:v1.6

2. build

   cmake

   mkdir ~/intel/dlstreamer_gst/build cd ~/intel/dlstreamer_gst/build cmake -DCMAKE_INSTALL_PREFIX=/opt/intel_test/dlstreamer_build ..

   make

   make -j sudo make install

4)config export GST_PLUGIN_PATH=/opt/intel_test/dlstreamer_build/lib:$GST_PLUGIN_PATH export LD_LIBRARY_PATH=/opt/intel_test/dlstreamer_build/lib:$LD_LIBRARY_PATH

5)test
