Composite TV OUT WORKING in Orange Pi One H3, 6.12 current

[Error1429]

Hello, I found this guide: https://github.com/robertojguerra/orangepi-zero-full-setup/blob/main/README2.md
I followed the steps and built an Armbian image with current 6.12 kernel and now TV OUT (CVBS, Composite Video), after soldering a cable to the video pin on the board, is working on my Orange Pi One with an Allwinner H3 CPU (the patches might work for other H3/H2+ boards). I would like to get that functionality incorporated into Armbian.

I suggest - if you want to continue with this approach - to add this as an extensions since having the necessary patches built-in for a board that needs hw modifications makes no sense.

That is a lot of work to get video for TVs that today have HDMI anyway. The audio out for an orangepione would also require audio amplifiers. Not many people have the skills to solder to the tiny pads on the orangepione and could easily destroy the board.

 

HDMI for the orangepione works very well for both audio and video.

That said, the orangepione with 512KB memory is under powered to run a desktop environment.

I think having a direct Composite output could be used with for example car monitors or other things, I don't see why it shouldn't be supported out of the box and it might work on all H3-based boards, some of which have a dedicated pin inside the headphone jack. For example Orange Pi PC. Also, composite video is supported from the start on a Raspberry Pi Zero, which also requires soldering to get it to work. I would say that more people are able to solder one pin rather then search the whole internet how to compile the whole kernel with patches. The video pin on the Orange Pi One isn't really that hard to access as it is on the bottom of the board.

@Error1429 If you were to submit a well thought out PR along with the necessary doc and website updates, I'm sure this would be accepted and incorporated.  But I think the feedback thus far as that this isn't something of high enough priority to ever being incorporated with Armbian's very limited resources.
