Seeking during dragging is helpful, because it allows you to move the
position around and see occasional frames to check where you've moved to.
The optimal strategy would seem to be to seek whenever released, or
to seek every 1/25 of a second to the new drag position otherwise.
Possibly, audio-only data should seek at a different frequency (I quite
like the squeek effect I get when dragging around the position in an mp3 at
Perhaps this could be implemented by putting a check in
gstmediaplay.c: gst_media_play_slider_changed() to see how long ago the
last seek was, seeking only if it's long enough ago. Otherwise, a "desired
seek position" would be set, and the seek would happen after sufficient
time in the idle function. If noone produces a patch by monday I'll take a
look at it: I have a wedding to go to tomorrow so can't look at it
[Another thing is that pressing escape during a drag should also cancel the
whole seek operation, seeking back to the position when the drag started.]
