I just double checked with ST and STiH412 is a STiH407 family based SoC so support still exists for this upstream. No idea what if any security is enabled on this product though. Most probably the A/V stack on it will be SDK2, although native upstream multimedia drivers for this chipset are looking pretty good now.
