Stop problems

Hello,

First I do all the stuff to build the pipeline. Works so
far..

Then I record a stream:

void record (char *file)
{
  g_object_set (G_OBJECT (sink), "location", file,
NULL);
  gst_element_set_state (pipeline, GST_STATE_PLAYING);
}

And I stopt it:

void stop ()
{
  gst_element_set_state (pipeline, GST_STATE_NULL);
}

If I start recording in another file again I get this:

WARNING **: Changing the `location' property on filesink
when a file is
open not supported.

If I unref the complete pipeline at stop() and rebuild it a
record() it
works. But I don't expect this is needed. So what operation
is really
needed to start recording in a new file? Or have I really to
build a
new pipeline?

regards
Andreas

The filesink must be in the READY or NULL state when you
change the
location (as the file is not opened then).

Hm, could you tell me how I do this? I tried various
commands, but I
get the same error message or a segfault.

I don't know what you miss, states are set using using
gst_element_set_state, and you already seem to know this
because you use
it just fine.  To elaborate a little bit: The problem you
face in your
program is how you call your "record" function. 
Apparently it is called
at some point where the sink is in the PLAYING or PAUSED
state.  To fix
this, you could unconditionally set the sink's state to
READY before
setting the location:

void record (char *file)
{
  gst_element_set_state (sink, GST_STATE_READY);
  g_object_set (G_OBJECT (sink), "location", file,
NULL);
  gst_element_set_state (pipeline, GST_STATE_PLAYING);
}

That should make the error go away.
