Rockpi4 is a RK3399. It's a well supported SoC, except for it encoders.
There is no mainline encoding yet (there is on ChromeOS). But Rockchip
support (MPP) is fully open source and comes with working set of GStreamer
elements. The OMX stack is only supposed to be used by the Android JVM

They seem to make a device based on RK3688 chip, witch is Rockchip top of
the the line. Appart from booting and showing a serial terminal, do not
expect much to work yet mainline Linux.
The vendor stack is not super stabl e, but works. They still provide the
same MPP library with full GStreamer support. You should not consider OMX.
