The problem about gst_element_set_state.

[forestzhu]

Hi all,
I met trouble in gsteamer program.
Sometimes the  program will crash 
when I use the " gst_element_set_state" to set the pipeline to NULL .

my code likes below:

        if (player->pipeline)
        {
            DEBUG_LOG("pipeline=>%p ...",player->pipeline);
while(GST_STATE_CHANGE_FAILURE == gst_element_set_state (player->pipeline,
GST_STATE_NULL))
            DEBUG_LOG("fail to change pipeline state...");
DEBUG_LOG("after set state");
            sleep(1);

            g_object_unref (player->pipeline);
            player->pipeline = NULL;
        }

I confirmed before set_state the player->pipeline 's mem_address is correct
.
And the  "DEBUG_LOG("fail to change pipeline state...");" and
"DEBUG_LOG("after set state");" will not run.

Anyone can give me some informations?

Thanks for any hint!

Regards!
