* gst/gstbuffer.h:
Change GstBuffer private structure element names. (all files)
* gst/gstqueue.c: (gst_queue_init), (gst_queue_getcaps),
(gst_queue_link):

Implement getcaps/pad_link functions that handle the case where
there are data in the queue.

* gst/gstqueue.c: (gst_queue_init):
Use better defaults for when a queue should block. This
gets rid of jerky playback for quite a few files.
It takes more memory.

* gst/gstqueue.c: (gst_queue_handle_pending_events),
(gst_queue_chain), (gst_queue_handle_src_event):
implement timeout for sending events. Workaround for if the
pipeline on this queue is not passing any data.
Original commit message from CVS:
Fix a deadlock that happens if the next element sends an event and the previous element sends a buffer where the queue is full. See the comment in the code for the rest.
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:
s/GstBuffer/GstData/ in the API where you can pass events. Fix the plugins to deal with that. Fixes#113488. Also includes scheduler patches, and probably fixes some queue bugs relating to events and buffers.
Original commit message from CVS:
implement translatable error messages using gerror.
Includes bugfixes for:
- crash when unlinking Ghostpads
- make *_PAD_* macros use glib casts
- make spider typefinding merge buffers correctly
Original commit message from CVS:
GST_DEBUG reorganization
This is a big diff (ca 450k), containing loads of stuff:
- gstinfo.[ch] complete rewrite
- changing of all GST_DEBUG messages to reflect that change
- reorganization of subsystem disabling
- addition of gstconfig.h.in so we can track the disablings
- <gst/gst.h> does not include <unistd.h> and <config.h> anymore
- documentation updated for gstinfo stuff (build the docs yourself to know what changed)
- bugfixes for making of the docs (files from CVS are not deleted anymore
- testsuite for debugging changes in testsuite/debug
expect breakage
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:
Ouch: gst_element_dispose does a state change to NULL. Change the state to NULL yourself if you dispose plugins that reference some of the freed memory on state changes.
This is probably broken in lots of cases.
Original commit message from CVS:
- Proxy the get_caps function slightly differently. This is potentially
dangerous as it works quite differently. My tests seem to work though and
it fixes the play-multi-file-segfault in the player.
Original commit message from CVS:
Provide intrastructure to not have to pass NULL buffers on errors and
interrupts, this should fix some issues with the optimal scheduler.
Original commit message from CVS:
- Make the return GList of gst_element_get_pad_list as const
- Pad scheduler refactoring
- Remove gst_pad_set/unset_scheduler as it's not needed
- Reimplement gst_pad_get_scheduler using the parent scheduler
- Remove gst_pad_peek as it cannot work reliably
- Remove the pad bufpen, replace with scheduler private gpointer
- Make queue use the new _get_scheduler implementation
- Remove _pad_unset_scheduler from GstScheduler
- Remove LOOP_SEEK mode from aggregator
- Other fixes for API changes.
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:
Whan the buffer is filled, the buffer is kept and added to the queue
when there is room again. Don't do this after a flush.
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:
Created an overridable method for seeking on an element, along with a default
implementation.
make queue flush on discont (not entirely correct)
removed the new_media from the discont event.
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.
