Hello, A newbie here can anyone give me an instruction on how to set Analog Video as Output display in Orangepipc, I am using Armbian Buster with mainline based kernel 5.9.y.  

Providing logs with 

armbianmonitor -u

 helps with troubleshooting and significantly raises chances that issue gets addressed.

TV out is not supported on mainline kernel at the moment.

https://lxr.missinglinkelectronics.com/uboot/doc/README.video did you try this?

 

mainline U-Boot also don't have TV out support for H3, unless out-of-tree patch is included in Armbian (I'm not sure)... Anyway, this would bring only simplefb support which has no features - no planes, only one bit depth, one color format, no double buffering, etc.

I asked about this in the #linux-sunxi channel some time last year. I believe it was @Icenowy who was actually sitting on a mainline patch to enable TV out, but there was presently no way to detect whether there is a cable inserted in the AV socket, or whether it's hooked up to a TV, and there is too little demand for the feature for anyone to bother.

There is a way to detect if cable is inserted or not, I implemented this for U-Boot, but driver never landed there - I never found enough motivation to update it according maintainers requests. For reference: https://github.com/jernejsk/u-boot/commit/ed5b310342eea0efe46f33bda8b725589ad206d5
