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).
