Original commit message from CVS: 2004-07-16 Julien MOUTTE <julien@moutte.net> * sys/ximage/ximagesink.c: (gst_ximagesink_handle_xerror), (gst_ximagesink_check_xshm_calls), (gst_ximagesink_ximage_new), (gst_ximagesink_ximage_destroy), (gst_ximagesink_sink_link), (gst_ximagesink_chain), (gst_ximagesink_buffer_free), (gst_ximagesink_buffer_alloc): * sys/ximage/ximagesink.h: * sys/xvimage/xvimagesink.c: (gst_xvimagesink_check_xshm_calls), (gst_xvimagesink_xvimage_new), (gst_xvimagesink_xvimage_destroy), (gst_xvimagesink_chain), (gst_xvimagesink_buffer_free), (gst_xvimagesink_buffer_alloc): * sys/xvimage/xvimagesink.h: Getting the 2 video sinks synchronized again. Using internal data pointer of the x(v)image to store image's data to be coherent with the buffer alloc mechanism. Investigated the image destruction code to be sure that everything gets freed correctly.
