media acceleration

[eloon]

Hi, does anyone know how to get hardware video acceleration on orange 4 lts? I've looked around and I saw that rk3399's multimedia support can be enabled using the rk3399 legacy multimedia framework. But that requires a legacy buster image, which doesn't exist for the orange pi. I've tried to compile it myself, but it seems the compile script won't allow it. Is it really impossible to compile a legacy kernel for orange pi 4 lts?

Mainline kernel has fairly compliant decoder support for rk3399, see fluster-run-nanopc-t4.log for reference. Only this patch set is yet missing for HEVC decoder support. Current gstreamer framework provides out-of-the-box support, FFMPEG framework still requires several pending patches that need to be applied for v4l2-request support.
