| 20 | * This file reproduces the bug in the bugreport #143777, as can be seen at |
|---|
| 21 | * http://bugzilla.gnome.org/show_bug.cgi?id=143777 - the issue is that when |
|---|
| 22 | * pausing a pipeline while the chainhandler is still running, then unlinking |
|---|
| 23 | * the pad that's chain function is called and relinking it clears the buffer |
|---|
| 24 | * that was stored for sending the event. gst_pad_call_chain_function needs |
|---|
| 25 | * to check that. |
|---|
| 26 | * The fix is in gstpad.c, revision 1.327 |
