Refactor an cleanup queue a bit.
Do better time level calculations that also work when the srcpad is not
yet running.
Remove some unneeded debug lines.
* tests/check/elements/queue.c: (GST_START_TEST), (queue_suite):
Added testcase for time level measurement.
Try to make some stuff more racefree.

* plugins/elements/gstqueue.h:
Be smarter when calculating the current amount of data in the queue by
measuring the difference between start and end timestamps (in running
time) inside the queue. Fixes#432876.
API: GstQueue::pushing to notify elements that we are pushing data again
since the running signal is rather broken for this purpose.

(gst_queue_set_property):
* plugins/elements/gstqueue.h:
In queue, when EOS is received, if minimum threshold > max_size -
current_level, there is chance that queue blocks forever in conditional item
del wait. This is because the queue is not emptied completely due to minimum
threshold.
Here is another approach. Instead of setting cur_levels to max in EOS, just
zero all minimum threshold levels. This should make sure that queue gives out
all data. When going to READY (stop) state, just reset the original minimum
threshold levels.
Fixes#336336.

with unconnected srcpads, then the rest.

Set the pad activate mode even if it does not have an activate
function.

Some fixes for the peer_get_caps() change.

Implement getcaps/pad_link functions that handle the case where
there are data in the queue.
Original commit message from CVS:
This is either a rewrite or a large bugfix to the queue element, whatever
you prefer to call it.
* upstream event forwarding now works. This should fix Julien's issues.
* this queue allows setting a min. treshold size and a max. limit size
in bytes, buffers and time before the queue allows the next element
to pull data or the previous element to push data into it. This is
very interesting for network-related buffering. Also includes signals
et all for the end user application.
* Events are no longer part of the queue's "size", they're essentially
seen as "void data". they have no size or time associated with them
anyway, so this shouldn't really sound weird.
Original commit message from CVS:
Add patch for better buffering (especially useful for network streaming), see #108268 - kudos go to janzen@pixelmetrix.com
Original commit message from CVS:
- Removed bufferpool code and move that to gstbuffer.c
- implemented refcounting on GstData
- implemented new buffer code based on Company's work in the EVENTS2 branch
- added boxed types for GstData/GstEvent/GstBuffer/GstBufferPool
- added refcounting to bufferpools and events
- use lockfree allocation for buffers
- simplified the clock, use lockfree allocation
- use GQueue in GstQueue for faster access to the tail element
- update core plugins to the new event API
Original commit message from CVS:
put upstream events in an async queue and resend them at the start of the chain. not working as expected yet but a start
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.
Original commit message from CVS:
Reparented everything to GstElement, removing GstSrc, GstSink, GstFilter,
and GstConnection. Also fixed a bug in gst_bin_iterate_func.
Original commit message from CVS:
More massive changes to the scheduling system. Moved the scheduling code
to gstscheduler.[ch], so an child bin can replace the scheduler.
Introduced the concept of chains, which are subsets of the list of managed
elements for a given manager bin, which get scheduled as separate entities.
gst_bin_iterate_func should be pretty much fixed now, the scheduling code
gets to do all the hard work.
Cothreaded case work in the couple tests I've tried, chained is next.
Original commit message from CVS:
The cothreads were not initialized in its thread context resulting in
severe stack corruption. This was very hard to track down.
We should be able now to modify some plugins to a loop based setup so that
we can get rid of the mp3parse and mp1videoparse elements.
Modified the GList to a GSList in the queue.
Original commit message from CVS:
This is the audio/video sync release.
Changed the mpegvideoparser to parse complete pictures. Added the PTS
timestamps to the pictures.
Added PTS timestamps to the MPEG audio frames.
Made the clock a littlebit better.
Gstplay now uses two more threads one for video, one for audio playback.
Added the first QoS callbacks for the pads.
hopefully fix an mmx compilation problem.
Original commit message from CVS:
Documentation updates. All standard library objects and standard
elements are documented. Modified some of the elements to more
accuratly report about their arguments so the documentation builds
more reasonable output.
Added aviencoder and jpegencoder elements (not working yet)
