You forgot to select glib2. Even if gstreamer needs it, miraclecast
needs glib for itself, too, so you need to select it.

> +	select BR2_PACKAGE_GSTREAMER

Don't you also need at least some codecs?

Looking at res/test_viewer.sh, it seems you need at least those:
    udpsrc rtpjitterbuffer rtpmp2tdepay tsdemux h264parse avdec_h264
    autovideosink

comment "miraclecast needs systemd and a glibc toolchain w/ threads, wchar"
        depends on BR2_USE_MMU
        depends on !BR2_TOOLCHAIN_USES_GLIBC || !BR2_USE_WCHAR \
                || !BR2_TOOLCHAIN_HAS_THREADS || !BR2_PACKAGE_SYSTEMD

Please comment on why this is needed, like:

    # Straight out of the repository, no ./configure
    MIRACLECAST_AUTORECONF = YES

I won't repeat what's already been said by Baruch, since I agree with
what he said.

/me is looking forward to seeing that integrated! :-)
