    Ooh nice! Sure hope it extends to Android devices soon, those phones really need that long lived support. It's only one of the various pieces of hardware that need open source drivers, but it's a critical and important start.

    Open source video decode and encode support would be great too.
    I won't claim to be an expert on the video enc/dec stack, but we are using the upstream v4l2 based video enc/dec driver (venus). AFAIU we are carrying a downstream kernel patch to enable UBWC (the "Q128" format), but that is just a workaround for lack of v4l2 support for fourcc modifiers and not intended to be a long-term solution. (And not required for functionality, just for better power/performance with higher resolution videos.)
