Summary: [directshowvideosink] Doesn't update the last frame
after a seek with the pipeline in PAUSED state.

GNOME milestone: Unspecified
On linux, using any of the availables videosink and with the pipeline in PAUSED
state, when I send a seek event, for example to the next frame, the new frame
is drawn by the video sink.
Instead on Windows, using the directshowvideosink, I need to set the pipeline
into PLAYING state before sending the seek event and then reset the pipeline to
PAUSED state to get the next frame drawn, which doesn't always work as
some times the seek is done before returning to the paused state.
I guess I could be a bug on the directshowvideosink.
Looking at the code, the Direct Show graph is paused when the pipeline goes
into PAUSED state, and it's set into playing state only when the pipeline
returns into playing state, and that should be why it doesn't draw the new
frame when the pipeline is paused. We should be able to update the graph when a
new frame comes into the video sink.
