LE already supports CVBS output on H2+, H3 and H5, it's just not enabled by default. That can be done by enabling appropriate DT TVE overlay in extlinux.conf. Currently overlays for enabling TVE exists for H3 and H5, but it would be trivial to add overlay for H2+ too. Note, H2+ is not officially supported in LE.
Thank you I see that you were the author of the armbian orange pi zero patch
Yes. Kodi also works with it
