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?
