How to install rust plugins compatible with version 1.16.3

Rz-Rz · October 1, 2024, 9:36am

Hello, looking for some info about how to build specific version of gst-plugin-rs to be compatible with specific version of GStreamer ?
Currently I am using GStreamer 1.16.3 and I can’t manage the installation of gst-plugin-rs. I get this error :

error: failed to run custom build command for `gstreamer-sys v0.24.0 (https://gitlab.freedesktop.org/gstreamer/gstreamer-rs?branch=main#5c395003)`

Caused by:

You will need to install the package that contains the GStreamer library header files. On debian/ubuntu that would be sudo apt install libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev libgstreamer-plugins-bad1.0-dev.

If you installed GStreamer yourself into a different prefix you may need to set PKG_CONFIG_PATH to the pkgconfig directory in the prefix.

I download that and I get the following :

It seems it looks for version 1.24 even though I have version 1.16.3 installed…

Rz-Rz · October 1, 2024, 10:36am

It seems this is the specific line that is causing a problem :

  pkg-config exited with status code 1    
  > PKG_CONFIG_ALLOW_SYSTEM_CFLAGS=1 pkg-config --libs --cflags gstreamer-1.0 gstreamer-1.0
 >= 1.24

Also It seems that the package are not available on Ubuntu :

How do you build the plugins?

That looks like a problem on your side, see e.g. libgstreamer1.0-dev. Did you forget to run apt update before and don’t have any package index inside your container?

Rz-Rz · October 2, 2024, 10:42am

I managed to fix the problem by using the version where the plugin I need was introduced, so on branch 0.9 if I’m not mistaken. And building GStreamer from source.
Then I use cargo cbuild -p for the specific plugin I need and I specify with the prefix the path where my gstreamer is installed and it seems to work.
However the version I am currently using GStreamer which is v1.16 is not compatible with v0.9 of rust plugins. So I plan to move to version 1.20 which is on Jetpack 6 and for the moment I will use it on a docker.

Version 1.20 of GStreamer seems to be compatible up to v0.11 of the rust plugins so I will be using both of those.
However I have trouble installing version1.20 of GStreamer with all the plugins.
Here’s my dockerfile :

# Use a base image with the necessary dependencies
FROM ubuntu:20.04

# Set environment variables
ENV DEBIAN_FRONTEND=noninteractive
ENV RUSTUP_HOME=/usr/local/rustup
ENV CARGO_HOME=/usr/local/cargo
ENV PATH=$CARGO_HOME/bin:$PATH

# Install dependencies
RUN apt-get update && apt-get install -y \
    build-essential \
    ninja-build \
    libtool \

    automake \

    libgstreamer1.0-dev \
    libgstreamer-plugins-base1.0-dev \
    git \
    curl \
    sudo \
    ca-certificates \
    libssl-dev \
    libxml2-dev \
    libharfbuzz-dev \
    libopenjp2-7-dev \
    && apt-get clean

RUN pip install meson

# Install Rust and Cargo
RUN curl https://sh.rustup.rs -sSf | sh -s -- -y --default-toolchain stable
RUN $CARGO_HOME/bin/rustup update
RUN $CARGO_HOME/bin/cargo install cargo-c

# Clone the gst-build repository
RUN git clone --recurse-submodules https://gitlab.freedesktop.org/gstreamer/gstreamer.git

# Set the working directory
WORKDIR /gstreamer

# Optionally checkout a specific branch or version, like 1.20
RUN git checkout 1.20

# Configure and build GStreamer with all plugins
RUN meson setup builddir && meson subprojects update && meson compile -C builddir && meson install -C builddir
# Set entry point (optional)
ENTRYPOINT ["/bin/bash"]

To solve it I tried to install some libraries it didn’t work :

    libxml2-dev \
    libharfbuzz-dev \
    libopenjp2-7-dev \

And I get this error :

Also I tried to clone recursively, and it didn’t fix anything.

Most plugins in gst-plugins-rs up to git main are compatible with GStreamer 1.14 and newer. Some require a newer version of GStreamer, some can optionally make use of a newer version.

From your description it’s not clear how you’re building gst-plugins-rs exactly, and which plugin(s) you need.

Rz-Rz · October 2, 2024, 11:04am

I need the webrtc and the webrtchttp plugin.

I just retried the steps one by one on my jetson with 1.16.

I did cargo cbuild -p gst-plugin-webrtc --prefix=/usr
on /net/webrtc/

I get this error:

Yes that plugin requires 1.22, and you’re generally not going to have a lot of fun with webrtcbin before 1.22. Better to update to at least 1.22, even better 1.24.

Unfortunately NVIDIA (looks like you’re doing this on some NVIDIA Jetson?) doesn’t provide up to date GStreamer packages, so you’ll have to build it yourself.

Rz-Rz · October 2, 2024, 3:03pm

Yes I’m using Nvidia Jetson. I will have to use a Docker with GStreamer 1.24 I believe.

I’m wondering how can I have access to the C/C++ API to build an application with the webrtc ? Or if it is not possible is there another way to do this ?
