* gst/gstutils.h:
|
||||
* gst/gstutils.c (g_static_rec_cond_wait)
|
||||
(g_static_rec_cond_timed_wait): Removed, no longer needed.
|
||||
|
||||
* gst/gstbin.c: Remove terrible continue_state prototype.
|
||||
|
||||
* gst/gstelement.h (gst_element_continue_state): Make public.
|
||||
|
||||
* gst/gstelement.h:
|
||||
* gst/gstelement.c (gst_element_commit_state): Removed, replaced
|
||||
by continue_state. Fixes #319389.
|
||||
|
||||
* gst/gstindex.h (GstIndexFilter): Actually pass on the user_data.
|
||||
Really fixes #168438. However I don't see anywhere where the
|
||||
filter function is called... stupid GStreamer...

* gst_element_commit_state:

* @element: a #GstElement to commit the state of.
|

*
|
||||
* Commit the state change of the element. This function is used
|

* by elements that do asynchronous state changes.
|
||||
* The core will normally call this method automatically when an

* element returned SUCCESS from the state change function.
|

* Elements that return ASYNC from the change_state function should
|

* eventually call this method from the streaming thread to signal
|
||||
* successfull state change completion.
|
||||
*
|
||||
* If after calling this method the element still has not reached
|
||||
* the pending state, the next state change is performed.
|
||||
*
|

* This function can only be called with the STATE_LOCK held.
|

*
|
||||
* Returns: The result of the commit state change.
