Not sure I did this correctly but here's what I got. dtb.0.dts

Always use main branch, older branches are here for reference and to build with sources at the state of initial build. We had several bug fix builds after point release, but they were made from main branch ... as we don't backport commits to frozen branch. Not enough people ... OS version is not determined by build framework, but externally. https://github.com/armbian/os/blob/main/stable.json Which version is bumped when any new Armbian package is sent to the repository. You can also set version with a parameter IMAGE_VERSION=25.2.3 ... In theory, if we would have "endless" computing / storage resources, we could make RT kernels for all variants. Currently, this is a bit insane as there are too many kernels.

Hi @Nick A The problem appears to be at my end, anyway managed to download the ffmpeg-vl42-request debs in the end and will be testing shortly. Thanks for the patches, I only had a slight hiccup when trying to integrate 2 of them. I found that patch 556 no longer appears to be necessary as those changes already appear to be implemented within my current Armbian build fork. The A10 and A20 use the Mali 400 so I have also borrowed patch 125. Good to here the CMA no longer need to be adjusted. I will update once my latest build has finished compling Thanks Ryzer

Do you know if the BSP kernels perform any better hw acceleration than the mainline kernel? Is the repo that you host built on this branch https://github.com/jernejsk/FFmpeg/tree/v4l2-request-n7.1 with Libreelec patches applied?
