Description Vincent Torri 2006-01-04 08:05:57 UTC 
When I use my usual test program : 

http://www.iecn.u-nancy.fr/~torri/files/gstreamer_seek/seek.c

with an ogm file, and when I seek to times less than 4s, then I get the message:

(seek:17173): GStreamer-CRITICAL **: gst_object_unref: assertion `GST_IS_OBJECT (object)' failed

You can test that with the program above and the file:

http://www.iecn.u-nancy.fr/~torri/files/gstreamer_pb/blood.ogm

it comes from gstoggdemux.c, line 1664, when target is decreased from a time of 4s, that is, when target is equal to 0, actually.

i've tried to fix that but i don't understand how the seek works. If someone can tell me what to look at, maybe i'll try to fix that.

confirming.
To test change the line that gets the framerate with:
 gst_structure_get_fraction (structure, "framerate", &num, &den);
 framerate = num / den;

bracktrace with fatal_warnings:

The warning should be fixed with this commit:
2006-02-19  Luca Ognibene  <luogni@tin.it>

	* ext/ogg/gstogmparse.c (gst_ogm_parse_chain): 
	  there's no need to call gst_object_unref if i remove
	  the pad with gst_element_remove_pad (fix warning on #325732)
