CVBS Output

The 4Kopen board has support for analog CVBS output via a 3.5mm TRRS jack. This connector provides composite video, and stereo audio - e.g: Yellow, White and Red RCA connectors.

This can be enabled by running the commands below:

media-ctl -l '"Main-PIP":1->"analog_hdout0":0[0]'
media-ctl -l '"Main-PIP":1->"analog_sdout0":0[1]'

This will present framebuffer 1 (/dev/fb1) on the CVBS output.
