Subject: [PATCH] lavfi/video: set output frame w/h properties in
default_start_frame()
Use the same values of the video output link.
Avoid the need to override the default_start_frame() with an ad-hoc
start_frame() callback.
In particular, fix the super2xsai filter which was setting the
input w/h values in the output.
