Meta Question

[ht techdev]

Hi
Unfortunately, doesn't seem to work. Did the following, to test it: (Below, GstXxxMeta is one of the Meta types that I wish to copy)
...
     gboolean stat=gst_buffer_copy_into (outBuf, inBuf, GstBufferCopyFlags(GST_BUFFER_COPY_METADATA|GST_BUFFER_COPY_DEEP), 0, -1);
      if(stat){
          g_print("Copied all meta\n");     // This prints
      }else{
          g_print("Meta copy failed\n");
      }
      GstXxxMeta *xxx_meta=gst_buffer_get_xxx_meta (outBuf);
       if(xxx_meta){
          GST_INFO_OBJECT(self,"Copied Meta =%d \n", vui_meta->xxxmeta->Val_1); // Does not print
       }
      xxx_meta=gst_buffer_get_xxx_meta (inBuf);
       if(xxx_meta){
          GST_INFO_OBJECT(self,"Org Meta =%d \n", vui_meta->xxxmeta->Val_1); // Does print
       }
...

"Copy Meta" line does not appear at all, while, "Copied all meta" prints out.
Any thoughts?
Cheers,

gst_buffer_copy_into (new, old, GST_BUFFER_COPY_METADATA, 0, -1);

might do the trick.
