Update:

1) commenting out "base = self->seek_start - start;" in
gst_deinterlace_sink_event() makes seeking work, but
2) commit "deinterlace: Refactor deinterlacing as preparation for
supporting more color formats" (the first in the series) breaks 50fps
video (deinterlaced videos become 25fps only), so I can't tell if last
patch really does what advertised :-)
