Has anyone been able to get a signal from the av/composite/cvbs port?

I'd like to connect my rock64 to an old tv. I tried with an av to rca cable, but it's not flush. Attaching images:






Is this normal? I tried with android 9 stock and ubuntu bionic image. On hdmi it works fine.

Previously tested with stock Android using composite video and works well. Please make sure you are using correct breakout cable. For AV breakup cable diagram, please review at PINE64 wiki page.

Sorry for the late reply. Thanks for the tip of using stock android, I finally got cvbs output to work in android 7.1. This is the link https://wiki.pine64.org/index.php/ROCK64...0171204.5D
I tried with version 8 and 9, but could not get any signal.

I spliced a phone headset jack with a composite video cable. The ground and video signal are reversed compared to a standard 3.5mm rca cable.
