It might be yuck, but it's a feature other movie players implement, and
something we implemented a long time ago:
commit 9567aa7563ddd1cb6d38ee65bc42eb6ff5942804

    added /apps/totem/auto_resize implement automatically changing the
ratio

            * data/totem.schemas.in: added /apps/totem/auto_resize
        * src/gtk-xine.c: (frame_output_cb), (gtk_xine_idle_signal),
        (gtk_xine_ratio_fits_screen), (gtk_xine_set_scale_ratio):
        implement automatically changing the ratio when the video
changes size
        (Closes: #92320)

Note that it's disabled by default.

gtk_container_check_resize() is lacking documentation in my day old
checkout of gtk+.
