Andy Wingo e040bb2dbe gst/gstelement.h (GstState): Renamed from GstElementState, changed to be a normal enum instead of flags.
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.

/*
* Test three ways of going non-lineairly to PLAYING. Both tests have a
* thread containing a fakesrc/sink.
*
* Test1 tests by adding fakesrc/fakesink, setting fakesrc to PLAYING
* (which should increment the container state) and then synchronizing
* state and see if the bin iterates. This reflects bug #123775.
*
* Test2 does the same, but emits EOS directly. This will (in case of
* race conditions) sometimes lead to a state-change before the previous
* one succeeded. This bug is not fixed yet (999998).
*
* Test3 tests by adding fakesrc, putting thread to PLAYING, adding
* fakesink, syncing state and see if it iterates. The group is sometimes
* activated before fakesink is added to the bin, which is a bug in opt
* and a race in core that is not fixed yet (999999).
