I have built the gst-plugin-pylon inside deepstream-l4t:6.4-triton-multiarch in a x86_64 workstation using qemu machine emulator. As the plugin depends on libnvbufsurface.so library for enabling NVMM feature, I download the L4T BSP inside the container, extract it and copy the corresponding library in /opt/nvidia/deepstream/deepstream/lib. I provide the code snippet in the dockerfile below:

FROM --platform=linux/arm64 nvcr.io/nvidia/deepstream-l4t:6.4-triton-multiarch
...
ARG L4T_PATH=https://developer.nvidia.com/downloads/embedded/l4t/r36_release_v3.0/release/jetson_linux_r36.3.0_aarch64.tbz2
RUN wget ${L4T_PATH} \
    && tar -xf jetson_linux_r3*aarch64.tbz2 \
    && cd Linux_for_Tegra/nv_tegra \
    && tar -jxpf nvidia_drivers.tbz2 \
    && cp -aprf usr/lib/aarch64-linux-gnu/tegra/libnvbuf*.so.1.0.0 /opt/nvidia/deepstream/deepstream/lib/ \
    && cp -aprf usr/lib/aarch64-linux-gnu/tegra/libnvdsbufferpool.so.1.0.0 /opt/nvidia/deepstream/deepstream/lib/ \
    && cd /opt/nvidia/deepstream/deepstream/lib/ \
    && rm libnvbufsurface.so libnvbufsurftransform.so libnvdsbufferpool.so \
    && ln -s libnvbufsurface.so.1.0.0 libnvbufsurface.so \
    && ln -s libnvbufsurftransform.so.1.0.0 libnvbufsurftransform.so \
    && ln -s libnvdsbufferpool.so.1.0.0 libnvdsbufferpool.so \
    && cd /code_libs && rm -rf Linux_for_Tegra && rm jetson_linux_r3*_aarch64.tbz2
...

Also, I have previously installed the pylon SDK for arm64 in the container in /opt/pylon. The plugin is then built successfully with NVMM support inside the container as you can see below:

As, I want to deploy my application to a Jetson device, I build a docker image based on deepstream-l4t:6.4-samples-multiarch that contains only the runtime libraries of deepstream. I copy the plugin library libgstpylon.so and all the shared libraries it depends on at runtime into the container from the image I built previously (base). I provide the corresponding dockerfile code snippet below:

# Gst-pylon plugin

COPY --from=base /opt/pylon/lib/libNodeMapData_gcc_v3_1_Basler_pylon.so /usr/local/lib

When, I run the final production image on Jetson device I am taking the below errors:

Regarding the hardware setup, I use two basler GigE cameras each connected to a different network port in a basler GigE interface card that is connected on a Jetson AGX Orin via the PCIe bus.

I have also installed the pylon SDK on Jetson (out of the container) and I have verified that the cameras operate successfully. In addition, to verify that the cameras can be accessed from inside the container I have installed pypylon and I have run the startup.py sample successfully.

Has anyone with a similar setup experienced this problem? Can anyone give a direction in resolving this issue?

The above errors are also raised when I install and use the plugin natively on AGX Orin Jetpack 6.0 (L4T r36.3.0) with pylon SDK 7.4.0 installed. Thus they do not seem to be related to docker. Also, the version of the plugin that raises the above errors in my setup is 0.7.1-6-gf9dc08c. I downgraded the plugin version to 0.7.0-12-geffb041 by checking out feature/fix_build_on_pylon7.4.0 branch and the plugin works successfully without errors.

UPDATE

While the plugin works after I downgraded the version to 0.7.0 it does not work when running inside a container using the setup and the Dockerfile I described above. I am getting a segmentation fault. I provide the stacktrace below:

Is the fault raised because it cannot find the source file ../ext/pylon/gstpylon.cpp? If yes, why the source file is needed since we have built the plugin and using the final executable inside the container?

Also, I keep getting two messages globbing failed each time I inspect or use the plugin inside the container.

UPDATE

While the plugin works after I downgraded the version to 0.7.0 it does not work when running inside a container using the setup and the Dockerfile I described above. I am getting a segmentation fault. I provide the stacktrace below:

I managed to solve the above issue by copying all the contents of /opt/pylon/lib from the host into the container. I came up with this solution after checking with lsof what files are opened when I run the command gst-inspect-1.0 pylonsrc. I can mark this issue as closed, but the other issue about using the latest plugin with version 0.7.1-6-gf9dc08c and pylon 7.4.0 still remains unresolved.

Hi @kostastsing,

we now have binary debian packages for multiple debian and ubuntu versions:

https://github.com/basler/gst-plugin-pylon/releases/tag/v0.7.3

and an explanation to build the plugin debian packages for NVIDIA deepstream including nvmm support:
