ubuntu - GStreamer/Deepstream : No such file or directory when loading plugins

Question

Gstreamer 给我错误报告，它无法加载插件，因为它们的文件不存在。但是，这些文件确实存在。
输出:

为了重现该问题，您可以在同一目录中创建以下两个文件。
Dockerfile:

FROM nvcr.io/nvidia/deepstream:6.0-samples
ENV GIT_SSL_NO_VERIFY=1
RUN 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 wget
RUN apt install -y libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev
RUN pip3 install --upgrade pip
RUN pip3 install numpy opencv-python
RUN echo '/usr/local/lib/gstreamer-1.0' >> /etc/ld.so.conf
RUN ldconfig
RUN cd /opt/nvidia/deepstream/deepstream-6.0/sources && \
    git clone https://github.com/NVIDIA-AI-IOT/deepstream_python_apps.git
RUN cd /opt/nvidia/deepstream/deepstream-6.0/sources/deepstream_python_apps && \
    git submodule update --init
RUN wget https://github.com/NVIDIA-AI-IOT/deepstream_python_apps/releases/download/v1.1.0/pyds-1.1.0-py3-none-linux_x86_64.whl
RUN pip3 install pyds-1.1.0-py3-none-linux_x86_64.whl
COPY start_example.sh start_example.sh
RUN rm -rf ~/.cache/gstreamer-1.0/

start_example.sh :

cd /opt/nvidia/deepstream/deepstream-6.0/sources/deepstream_python_apps/apps/deepstream-imagedata-multistream
python3 deepstream_imagedata-multistream.py rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mov frames

然后运行:

docker build . -t deepstream-custom
docker run --gpus '"'device=0'"' -it --rm -v /tmp/.X11-unix:/tmp/.X11-unix -e DISPLAY=$DISPLAY  deepstream-custom sh start_example.sh

文件 librivermax.so.0和 libtritonserver.so在系统中找不到。

Answer 1

事实证明，这不是问题。如果你想使用 Triton Server，有一个专用的 docker 镜像。至于 Rivermax，如果您想使用它，文档中会提到它，但如果您不使用，您可以放心地忽略警告。
