ffmpeg | branch: master | Stefano Sabatini <stefasab at gmail.com> | Thu Jun 14 13:12:18 2012 +0200| [635a25954e96bc7b765dc84e9118fca0a61dcaf9] | committer: Stefano Sabatini

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.
