GStreamer | gst-plugins-base | Ver: HEAD CVS
Summary: xvimagesink xwindow_draw_border() slowness
Product: GStreamer
Version: HEAD CVS
Platform: Other
OS/Version: Linux
Status: UNCONFIRMED
Severity: enhancement
Priority: Normal
Component: gst-plugins-base
AssignedTo: gstreamer-bugs at lists.sourceforge.net
ReportedBy: ensonic at sonicpulse.de
QAContact: gstreamer-bugs at lists.sourceforge.net
GNOME version: Unspecified
GNOME milestone: Unspecified
if one sets xvimagesink->keep_aspect=TRUE xvimagsink centers the picture in
gst_xvimagesink_xvimage_put(). A few lines down it calls
gst_xvimagesink_xwindow_draw_borders(). This is causing quite a slowdown in
performance for us (just commenting out the _xwindow_draw_borders() call make
it much better).
Now the plan is:
* first only call _xwindow_draw_borders() if xvimagesink->keep_aspect==TRUE,
otherwise there will be no border anyway.
* next only do the centering and the border-drawing if the sizes have changed.
Finally I belive its up to the ui to paint the background black (or to what
ever). So wouldn't it make sense to have a 'draw-border' property (default
TRUE), so that if apps handle the sizing, they can paint the border?
