`kmssink`
=========

``kmssink`` is a GStreamer plugin designed to serve as a simple video sink, rendering video frames directly in a plane of a DRM (Direct Rendering Manager) device. 
This allows for direct display of video content on a DRM device, such as a display or a video output.

Here's a simple usage pipeline for ``kmssink`` in GStreamer:

.. Note::
    Remember to :ref:`stop weston service <stop-weston>` before running the pipeline with `kmssink`.

.. prompt:: bash

    gst-launch-1.0 -v videotestsrc num-buffers=30 ! videoconvert ! video/x-raw,width=640,height=480,format= RGB ! kmssink

In this pipeline:
    - ``videotestsrc`` generates a test video stream.
    - ``videoconvert`` converts the video format if needed.
    - ``kmssink`` renders the converted video buffer directly in a plane of a DRM device.
