Got it!
I try to add a transition, but the program hunged, if I remove the
transition codes , it worked.
the code:
//clip1[3:6]
offset=3*GST_SECOND;
inpoint=5*GST_SECOND;
duration=3*GST_SECOND;
priority=0;
uri = gst_filename_to_uri ("./shoe.mp4", NULL);
src = GES_CLIP(ges_uri_clip_new (uri));
g_assert (src);
g_free (uri);
g_object_set (src, "start",offset,"in-point", inpoint,"duration" ,
duration, "priority",priority,NULL);
g_assert(ges_layer_add_clip (layer, src));
ges_timeline_element_set_child_properties (GES_TIMELINE_ELEMENT (src),
"posx", 400, "posy", 400, "width",200,"height",200, NULL);
// add a transition code here
GESTransitionClip *tr ;
if (!(tr = ges_transition_clip_new_for_nick ( "crossfade")))
g_error ("invalid transition type \n");
g_object_set (tr, "start", (guint64) 6*GST_SECOND, "duration", (guint64)
2*GST_SECOND, "in-point", (guint64) 0, NULL);
g_assert(ges_layer_add_clip (layer, GES_CLIP (tr)));
//clip2 [8:11]
offset=8*GST_SECOND;
inpoint=3*GST_SECOND;
duration=3*GST_SECOND;
priority=1;
uri = gst_filename_to_uri ("./poc_backgroup.mp4", NULL);
src = GES_CLIP(ges_uri_clip_new (uri));
g_assert (src);
g_free (uri);
g_object_set (src, "start",offset,"in-point", inpoint,"duration" ,
duration, "priority",priority,NULL);
g_assert(ges_layer_add_clip (layer, src));
ges_timeline_element_set_child_properties (GES_TIMELINE_ELEMENT (src),
"posx", 400, "posy", 400, "width",200,"height",200, NULL);
