Original commit message from CVS: 2005-09-02 Andy Wingo <wingo@pobox.com> * gst/gstelement.h (GstState): Renamed from GstElementState, changed to be a normal enum instead of flags. (GstStateChangeReturn): Renamed from GstElementStateReturn, names munged to be GST_STATE_CHANGE_*. (GST_STATE_CHANGE): Renamed from GST_STATE_TRANSITION, updated to work with the new state representation. (GstStateChange): New enumeration of possible state transitions. Replaces GST_STATE_FOO_TO_BAR with GST_STATE_CHANGE_FOO_TO_BAR. (GstElementClass::change_state): Pass the GstStateChange along as an argument. Helps language bindings, so they don't have to use tricky lock-needing macros like GST_STATE_CHANGE (). * scripts/update-states (file): New script. Run it on a file to update it for state naming and API changes. Updates files in place. * All files updated for the new API.

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