Bus report just part of GST_MESSAGE_STREAM_STATUS

[llama]

Hello,

I am trying to find out the main reason i never get GST_MESSAGE_STREAM_STATUS types like GST_STREAM_STATUS_TYPE_START, GST_STREAM_STATUS_TYPE_PAUSE, GST_STREAM_STATUS_TYPE_DESTROY from bus.

But the only message type i got is GST_STREAM_STATUS_TYPE_CREATE and GST_STREAM_STATUS_TYPE_ENTER;

I already tried to use gst_bus_set_sync_handler and also gst_bus_add_signal_watch_full but it does not help.

So i try to figure out things like:
1. what actually those GST_STREAM_STATUS_TYPE_CREATE and GST_STREAM_STATUS_TYPE_ENTER means and why it's usefull ?
2. What should i do to get all others ?

Thanks, in advance!  :)
