I see: the usual curse of static libraries (I usually build shared myself to
gain a few second at linking):

avfilter_register_all() -> ff_lavfi_demuxer -> avfilter_register_all() ->
ff_vf_scale -> libswscale

(and the same for swr and postproc), but the libavfilter -> libswscale
dependency is not visible in the lavd Makefile.

It can be trivially fixed with:

+FFLIBS-$(CONFIG_LAVFI_INDEV) += avfilter swresample swscale postproc

but that will cause failures when something is disabled. I will need to
think about it to find a clean fix, but in the meantime people can test this
