The kmssink element interfaces with the DRM/KMS Linux framework and the Xilinx DRM driver through the libdrm library and the dri-card device node.
The kmssink element library uses the libdrm library to configure the cathode ray tube controller (CRTC) based on the monitor’s extended display identification data (EDID) information with the video resolution of the display. It also configures plane properties such as the alpha value.
