I guess, there's no hope for "easy" legacy build for orangepi4-lts, because there is no way to choose "legacy" in the GUI of armbian build (even with "EXPERT" flag), it's missing.
And if I try to force "legacy" via CLI flags, I get:
sudo ./compile.sh \
BOARD=orangepi4-lts \
BRANCH=legacy \
RELEASE=buster \
BUILD_MINIMAL=yes \
BUILD_DESKTOP=no \
KERNEL_ONLY=no \
KERNEL_CONFIGURE=no

So, i guess, for Orange Pi 4 LTS the only hope is that JMCC will have the opportunity to implement multimedia features for "current" or that at some point mainline catches up.
