How does LibreELEC realize VPU decoding?

1st Official Post

    LibreELEC Looks like can be use hardware decode on H6 board,But I can't found any userspace driver in rootfs,

    This confused me. I kown LibreELEC has cedrus kernelspace driver patch,but where is userspace driver?

    Does he don't need userspace driver?:?:=O

    Cedrus implements request API which can be used from userspace. Currently, LE patches ffmpeg to use this interface directly. I wouldn't say that there is userspace driver - it's not needed for this case.
