Hi Julian, A small API change you'll need to know about. GUI_SEND_KAA_VO_OSD_INVALIDATE_RECT now takes an array of rectangles, where the last rectangle has a 0 width for a sentinel. So now you just send one invalidation each time you call evas_render(). This prevents a possible flicker if the vo thread displays a frame while multiple regions are getting updated to the OSD in another thread.
So your osd_render() function will look something like ...
Evas_Rectangle *r; // array of rectangles
Evas_List *updates, *p;
int i;
updates = evas_render_updates(evas);
r = malloc(sizeof(Evas_Rectangle) * (evas_list_count(updates)+1));
for (i = 0, p = updates; p; p = p->next, i++)
memcpy(&r[i], p->data, sizeof(Evas_Rectangle));
r[i].w = 0; // sentinel
xine_gui_send_vo_data(stream, GUI_SEND_KAA_VO_OSD_INVALIDATE_RECT,
(void *)r);
free(r);
(Not actually compiled or tested, but you get the idea.)
Cheers,
Jason.
