problem with the property stream-info of playbin

[Julien Chaix]

Hi,

I have a problem when i try to get the stream-info from the element
playbin. I use the function  g_object_get (G_OBJECT (playbin),
"stream-info",&streaminfo, NULL); when the state changed from ready to
paused.But  the result  then is just a glist with only one element (type).

This is a piece of my code in my bus function
*************************************************************************
    case GST_MESSAGE_STATE_CHANGED:
                {
                    GstState    old, newState, pending;
                    GList            *theStreaminfo;
                    gst_message_parse_state_changed(message, &old,
&newState, &pending);

                   gPlayerState = newState;

                    if(old == GST_STATE_READY && newState ==
GST_STATE_PAUSED)
                    {
                        if(playbin !=NULL)
                        {
                            GList     *streaminfo = NULL;
                             g_object_get (G_OBJECT (playbin),
"stream-info",&streaminfo, NULL);
                           
                            if(streaminfo != NULL)
                            {
                                theStreaminfo=(GList *)theGinfoList;
                                g_list_foreach( streaminfo,
print_Streaminfo, NULL);
                                printf("length of glist
\n",g_list_length (streaminfo));            
                            }
                        }
                    }                    
****************************************************************************

And this is the function that I call for each glist

****************************************************************************
 static void print_Streaminfo(const gpointer list, gpointer unused)
 {
       printf("print_Streaminfo \n");
       gint streamtype;
       GstCaps     *gcaps;
       gchar     codec,decoder;
 

 
       g_object_get(G_OBJECT(list), "type", &streamtype, NULL);
       if(streamtype !=NULL)
       {
         //get  the caps
         g_object_get(G_OBJECT(list), "caps", &gcaps, NULL);
         if(gcaps !=NULL){
         printf("caps :%s \n",gst_caps_to_string(gcaps));
         }
         else
         printf("caps is NULL \n");  
 
         //get the codec
         g_object_get(G_OBJECT(list), "codec", &codec, NULL);
         if(codec !=NULL)
         printf("codec :%s \n", codec);
         else
         printf("codec is NULL \n");
 
         //get the decoder
         g_object_get(G_OBJECT(list), "decoder", &decoder, NULL);
         if(decoder !=NULL)
         printf("decoder :%s \n",&decoder);
         else
         printf("decoder is NULL \n");  

      }
}

I am sorry for my bad English but please help me
