The HDR10 pipeline supports the reception and insertion of HDR10 static metadata. This HDR10 metadata contains critical information needed to support HDR and will be carried throughout the pipeline - from the source to the sink.
Run the following gst-launch-1.0 command to display the XV20 HDR10 video on HDMI-Tx using the GStreamer pipeline (capture (HDR10) → encode → decode → display(HDR10)):
