[gst-devel] attaching a listener to autoplugging code

[Quan Nguyen]

Can you elaborate on what you mean that I am not connecting to "error" signals?  I don't quite understand.  I used gst_parse_launch and attached an identity (listener) after a spider, and I got the following error when using Gstreamer 0.6.4:
 
CRITICAL **: file gstsearchfuncs.c: line 332 (gst_autoplug_sp): assertion `sinkcaps != NULL' failed

When I used the exact same code in Gstreamer 0.7.3, it worked.  I would like to know how to make it to work in 0.6.4.  Does anyone have any suggestions?  
 
Here's a code snippet:
 
pipeline = gst_parse_launch ("filesrc name=my_filesrc ! spider ! identity name=listener ! osssink", &error);

filesrc = gst_bin_get_by_name (GST_BIN (pipeline), "my_filesrc");
g_object_set (G_OBJECT (filesrc), "location", "./sample.mp3", NULL);
  
listener = gst_bin_get_by_name (GST_BIN (pipeline), "listener");
g_signal_connect (G_OBJECT (listener), "handoff",
      G_CALLBACK (cb_manipulate), this);

You're not connecting to 'error' signals and such...

You're not actually giving a file location.
