+######################
+OBS Setup
+######################
+
+Requirements
+============
+
+- Ubuntu 24.04.3
+- Kernel image ``6.1.75-axon``
+
+Mesa3D Configuration
+====================
+
+Check your OpenGL version to verify Mesa3D installation:
+
+.. code-block:: bash
+
+   glxinfo | grep "version"
+   glxinfo | grep "renderer"
+
+For the RK3588, Mesa (Panfrost) only supports **OpenGL 3.1**. OBS requires **OpenGL 3.3 or higher**. To bypass this check (temporarily), you can override the Mesa version:
+
+.. warning::
+
+   Mesa version override is not recommended for general use, but it works fine for running OBS.
+
+.. code-block:: bash
+
+   export DRI_DRIVER=panfrost
+   export MESA_GL_VERSION_OVERRIDE=3.3
+   export MESA_GLSL_VERSION_OVERRIDE=330
+
+Dependencies
+============
+
+Install required development libraries:
+
+.. code-block:: bash
+
+   sudo apt install libobs-dev libasound2-dev

+
+Axon OBS Video Capture Plugin
+===============
+
+Install the ``v4l2-obs-plugin-axon`` for camera capturing:
