Dependencies
The GstSEI plugin has the following dependencies:
GStreamer
The GStreamer packages are likely already installed in your Ubuntu OS distribution. In case you want to double-check and install the missing packages, run the following commands.
sudo apt install libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev gstreamer1.0-plugins-base libgstreamer-plugins-bad1.0-dev gstreamer1.0-plugins-bad
Meson
The GstSEI plugin makes use of the Meson build system. To build correctly this plugin you need to use the latest version of Meson:
First, make sure python dependencies and ninja are installed
sudo apt install python3 python3-pip python3-setuptools python3-wheel ninja-build
Then, use pip3 to install Meson.
sudo -H pip3 install meson
Hotdoc
The GstSEI plugin makes use of the Hotdoc documentation. In order to install it you need to follow the next steps:
First, install the Hotdoc dependencies:
sudo -H pip3 install markupsafe==1.1.1 sudo apt install python3-dev libxml2-dev libxslt1-dev cmake libyaml-dev libclang-dev llvm-dev libglib2.0-dev libjson-glib-dev flex
Then, install their latest release version with:
sudo -H pip3 install hotdoc
Building the project
To build the GstSEI plugin natively on the hardware, on its simplest form, run:
meson build --prefix /usr/ ninja -C build ninja -C build test sudo ninja -C build install
For additional customization, you may refer to the following table of options:
Configure Option | Description |
---|---|
-Dexamples=disabled | Skip examples compilation |
-Dtests=disabled | Skip tests compilation |
-Ddoc=disabled | Skip documentation generation |
--prefix /usr | Set the installation path of the library |
Check the element
After installing the plugin test that the plugin is being properly picked up by GStreamer by running:
gst-inspect-1.0 sei
with expected output:
Plugin Details: Name sei Description Gstreamer plugin to add meta-data as SEI NAL units Filename /usr/lib/x86_64-linux-gnu/gstreamer-1.0/libsei.so Version 0.1.0 License Proprietary Source module gst-sei Binary package gst-sei Origin URL Unknown package origin seiinject: SEI Inject Meta-data seiextract: SEI Extract Metadata seimetatester: Helper element to insert a test GstSeiMeta to buffers. 3 features: +-- 3 elements
And also run:
gst-inspect-1.0 | grep sei
with expected output:
sei: seimetatester: Helper element to insert a test GstSeiMeta to buffers. sei: seiextract: SEI Extract Metadata sei: seiinject: SEI Inject Meta-data
