Original commit message from CVS:
add an optional timeout for when queue blocks. when timeout is reached a GST_EVENT_FILLER is sent downstream
This is needed for gst-player since videosink has to be in the same thread as the ui, and spider blocks when there is no video (thus freezing the ui).
Original commit message from CVS:
- The clock_wait now returns the difference between requested time and
unlock time.
- Misc defines like GST_SECOND in gstclock.h
- remove pre/post in gstelement.c until fixed.
- added release_locks to gstelement so that the element can unlock itself
- added some more predefined events.
- added folowing functions to gstpad:
- convert function: get the relation between formats on this pad
- query function: get stats about the pad (position/total/latency)
- internal connect function: find out how this pad connects to other
pad internally to the element.
- generic pad_dispatcher.
- removed the last bits of pullregion
- use release_locks on the queue.
- added some events to queue
- make gstthread use the new release_locks function
- make the scheduler use the new clock_wait functions
- added events to fakesink
- added query functions to filesrc
- swap type and offset in the bytestream seek API to match fseek
- added some event handling in bytestream.
Original commit message from CVS:
This is an attempt at not segfaulting on errors but reporting some
usefull info instead.
- bin changes so errors can propagate.
- changed the _FAST macros to _CAST because that is what they do.
- removed all references to cothreads out of the core, they are
really a scheduler issue, handler with a sched_private gpointer.
- added a live buffer count, for debugging buffer leaks.
- added error checking in gst_scheduler_state_transition this solves the
"out of cothreads" problem.
- GST_ELEMENT_NO_ENTRY == GST_ELEMENT_INFINITE_LOOP
- added 2 private element flasg for use by the scheduler
(_COTHREAD_STOPPING) is now
- added scheduler entry points:
- _yield : to create possible scheduling points.
- _interrupt: to stop execution of an element.
- _error: to signal en error condition to the scheduler.
- improved error messages for pads.
- signal gst_element_error where appropriate.
- added the a new bin to the parent before entering it so one can reference
its children.
- queue memleak fixes on dispose.
- added possible deadlock detection in queue (turned off be default)
- GstBasicScheduler is a real class of its own now, hiding its internal
variables.
- GST_ELEMENT_IS_COTHREAD_STOPPING is gone. either call explicit _yield
operations, or make a sane loop.
- Better state change handling in filesrc. Better error reporting/recovery
too.
- updated core plugins.
- detect non decoupled elements on scheduler boundries and error.
