Original commit message from CVS: 2004-02-18 Julien MOUTTE <julien@moutte.net> * sys/ximage/ximagesink.c: (gst_ximagesink_xwindow_update_geometry), (gst_ximagesink_renegotiate_size), (gst_ximagesink_handle_xevents), (gst_ximagesink_change_state), (gst_ximagesink_expose), (gst_ximagesink_init): Rework the way software video scaling works. So now we check on each chain call if the video frames are feeling the window. If not we try to renegotiate caps. On failure we memorize that and we won't try again for that PLAYING sessions. * sys/ximage/ximagesink.h: Adding a boolean to store the caps renego failure. * sys/xvimage/xvimagesink.c: (gst_xvimagesink_init): initialize the synchronous flag.
