I’m having kind of the same issue as this recently closed issue: GST_ELEMENT_FACTORY gstelementfactory.c:458:gst_element_factory_make: no such element factory "nvmsgconv"!
I can run a deepstream app that’s sending some messages using Kafka to the localhost. However, I would like to customize the messages which means I need to compile the nvmsgconv plugin in /opt/nvidia/deepstream/deepstream/sources/libs/nvmsgconv. However, even when I don’t change anything and compile it with make, and consequently run make install (basically copying it to /opt/nvidia/deepstream/deepstream-6.2/lib), it doesn’t work.
Running with GST_DEBUG=3 gives the following result:
I’ll add it as text as well so it’s searchable or can be copied:

Did you run the command below to install the protobuf?
sudo apt-get install libglib2.0-dev libjson-glib-dev uuid-dev libyaml-cpp-dev protobuf-compiler
Did you install the deepstream on your host or just use a docker? If you install it on your host, you can refer to the link below first:https://docs.nvidia.com/metropolis/deepstream/dev-guide/text/DS_Quickstart.html#dgpu-setup-for-ubuntu
Yes I did as instructed in the README in the plugin. By the way I’m using the de deepstream-6.2-devel image
Could you try to run sudo apt-get install libprotobuf-dev? It seems like relating to the dependencies of protobuf in your environment.
Still same error, I am using the docker container so I am running everything as root.
Maybe it’s also good to note that initially (both with and without the -dev) it didn’t compile at all. It said:#include <google/protobuf/port_def.inc>#include <google/protobuf/port_def.inc>#include <google/protobuf/port_def.inc>#include <google/protobuf/port_def.inc>
Then I found that because I ran “apt-get install libprotobuf” (with or without -dev) as root it got installed in /root/.local/. So I’ve added : “CFLAGS+= -I/root/.local/include” to the Makefile. Then it was able to compile the code, however I still have the error when running the pipeline.
I use the image too: nvcr.io/nvidia/deepstream:6.2-devel . It worked well in my environment. Could you use ldd command to investigate what dependent libraries are missing in your environment？ Like ldd -r libnvds_msgconv.so.
I included a text file in which I’ve documented all steps I took to get here from a new container.
however, ldd -r libnvds_msgconv.so returns the following:

About the first step, how do you start a docker with json file? Did you try to use docker run command to use docker directly?
It is a way to start and mount a directory directly into a container from visual studio code.
I got it from How To Develop and Optimize Edge AI apps with NVIDIA DeepStream | NVIDIA On-Demand
I took a look at the vscode logs and under the hood it is running:
docker run --sig-proxy=false -a STDOUT -a STDERR --mount type=bind,source=/home/bkos/test_msgconv,target=/workspaces/test_msgconv --mount type=volume,src=vscode,dst=/vscode -l devcontainer.local_folder=/home/bkos/test_msgconv -l devcontainer.config_file=/home/bkos/test_msgconv/.devcontainer/devcontainer.json --gpus all --name=test_msgconv --net=host -it -v /tmp/.X11-unix:/tmp/.X11-unix --env-file .devcontainer/devcontainer.env --entrypoint /bin/sh -l devcontainer.metadata=nvcr.io/nvidia/deepstream:6.2-devel -c echo Container started

Is your host using Ubuntu system and what is the version?
docker run --rm -it --gpus device=0 --runtime=nvidia nvcr.io/nvidia/deepstream:6.2-devel
You’re right. The way I’m starting the docker container adds “/usr/bin:/vscode/vscode-server/bin/linux-x64/b3e4e68a0bc097f0ae7907b217c1119af9e03435/bin/remote-cli:/root/.local/bin” in front of the PATH variable. In the image there is also a protoc binary present in /root/.local/bin, this is why it uses the wrong installation. Simply using “export PATH=/usr/bin:$PATH” adding the /usr/bin directory in front solves it.
Thank you so much for your help! It is greatly appreciated, have a nice day!
