<table cellpadding=3 cellspacing=0 border=0 width=100% bgcolor=white><tr valign=top><td width=100%>hi all, i have written a simple player using playbin . in the int main() function , i create a pthread which scans for key presses , and then i call player_initialise() int main(int argc,char **argv) { Create_keypress_scan_thread(scan_key_press); // creates a pthread for scanning user key presses player_initialise(); } void *scan_key_press() { } void player_initialise() { gst_init(NULL,NULL); loop = g_main_loop_new(NULL,FALSE); pipeline=gst_element_new("pipeline"); play=gst_element_factory_make("playbin","play"); ...................... set_uri(); gst_element_set_state(pipeline,GST_STATE_PAUSED); g_main_loop_run(loop); } void on_playkey() { gst_element_set_state(pipeline,GST_STATE_PLAYING); } void on_stopkey() { g_main_loop_quit(loop); gst_element_set_state(pipeline,GST_STATE_READY); // CREATES A SEGMENTATION FAULT HERE gst_object_unref(GST_OBJECT(pipeline); } the problem is when i am playing a media file and the user presses key for stop , it goes to on_stopkey() and creates a segmentation fault at " gst_element_set_state(.....,GST_STATE_READY.) " any ideas </td></tr></table><hr>Join Excite! - <a href=http://www.excite.com target=_blank>http://www.excite.com</a> The most personalized portal on the Web!
