We can use a shift for scaling the denominator instead of a divide since the
denom is always positive. This avoids having the compiler generate code for the
different rounding rules when scaling negative values.
64bit x86 has native 64x64->128 bit multiply that we can use with some inline
assembler to speed up large multiplications.
Use bsr to find the number of leading zeros more efficiently.
The new functions are
gst_util_uint64_scale_int_round()
gst_util_uint64_scale_int_ceil()
gst_util_uint64_scale_round()
gst_util_uint64_scale_ceil()
Fixes bug #590919.
This reverts commit bebfde7502.
This change shouldn't be done in a stable release series as
applications are actually expecting the sender to be an
GstElement. One example is totem.
Move the gst_pad_can_link() implementation from gstutils to gstpad and use
gst_pad_link_prepare() to make it work correctly and also check the caps.
Make the broken implementation in gstutils static.
Small cleanups in the _get_fixed_caps() function.
Fixes#575682.
This will be mostly useful in all elements that have some kind of internal
seek/index table. Currently almost all of them (or even all of them)
are using a linear search although the used array is already sorted,
wasting some CPU time without good reason.
Fixes bug #573623.

Original commit message from CVS:
* gst/gstutils.c: (gst_element_found_tags_for_pad):
Add FIXME for 0.11 to set the pad as message source and not
the element. Otherwise it's impossible to detect for which

or something similar to the pad.
Original commit message from CVS:
* gst/gstutils.c: (gst_element_get_compatible_pad):
Check if the caps of the pads are compatible before returning
a pad and claiming it is compatible. This, among other things,
fixes a bug with gst-launch where an incompatible pad is chosen
and linking fails. Fixes bug #544003.

Ensure that we set a capsfilter to NULL if we failed to link it

No need to check for unreffing srcpad, which is explicly NULLed
above (a trivial code cleanup).

Original commit message from CVS:

(gst_bin_change_state_func):
(de)activate src pads before calling state_change on the childs.
This is to avoid the case where a src ghostpad is blocked (holding the
stream lock), which would block the deactivation of the ghostpad's
target pad.

GhostPads now create their internal GstProxyPad at creation (and not
when they're linked, as it was being done previously).
The internal and target pads are linked straight away.
The data will also travel through the other pad in order to make
pad blocking and probes non-hackish (the probe/block now really happens
on the GhostPad and not on the target).
* gst/gstpad.c: (gst_pad_set_blocked_async),

* check/gst/gstutils.c: New file.
(test_buffer_probe_n_times): A simple buffer probe test. More to
come, foolios.
* gst/gstutils.c (gst_pad_add_buffer_probe): Connect to
have-data::buffer, not have-data.

peer' isn't quite right yet though.
(gst_pad_remove_buffer_probe, gst_pad_remove_event_probe)
(gst_pad_remove_data_probe): Change to take the guint handler_id
as their arg, not the function+data, which is more glib-like.

the signal emission to indicate if the data is a buffer or an
event.
(gst_pad_get_type): Initialize buffer and event quarks.

Original commit message from CVS:
2005-06-08 Andy Wingo <wingo@pobox.com>
* gst/gstutils.c: RPAD fixes all around.
(gst_element_link_pads): Refcounting fixes.
* tools/gst-inspect.c:
* tools/gst-xmlinspect.c:
* parse/grammar.y:
* gst/base/gsttypefindhelper.c:
* gst/base/gstbasesink.c:
* gst/gstqueue.c: RPAD fixes.
* gst/gstghostpad.h:
* gst/gstghostpad.c: New ghost pad implementation as full proxy
pads. The tricky thing is they provide both source and sink
interfaces, since they proxy the internal pad for the external
pad, and vice versa. Implement with lower-level ProxyPad objects,
with the interior proxy pad as a child of the exterior ghost pad.
Should write a doc on this.
* gst/gstpad.h: s/RPAD/PAD/, s/RealPad/Pad/.
(gst_pad_set_name, gst_pad_set_parent): Macros removed, use
gst_object API.
* gst/gstpad.c: Big changes. No more stub base GstPad, now all
pads are real pads. No ghost pads in this file. Not documenting
the myriad s/RPAD/PAD/ and REALIZE fixes.
(gst_pad_class_init): Add properties for "direction" and
"template". Both are construct-only, so they can't change during
the life of the pad. Fixes properly deriving from GstPad.
(gst_pad_custom_new, gst_pad_custom_new_from_template): Gone. For
derived objects, just set properties when creating the objects via
g_object_new.
(gst_pad_get_parent): Implement as a function, return NULL if the
parent is not an element.
(gst_pad_get_real_parent, gst_pad_add_ghost_pad)
(gst_pad_remove_ghost_pad, gst_pad_realize): Removed.
* gst/gstobject.c (gst_object_class_init): Make name a construct
property. Don't set it in the object init.
* gst/gstelement.c (gst_element_add_pad): Don't allow adding pads
with UNKNOWN direction.
(gst_element_add_ghost_pad): Remove non-orthogonal API. Replace
with gst_element_add_pad (e, gst_ghost_pad_new (name, pad)).
(gst_element_remove_pad): Remove ghost-pad special cases.
(gst_element_pads_activate): Remove rpad cruft.
* gst/gstbin.c (gst_bin_change_state): Use gst_pad_get_parent to
catch the pad's-parent-not-an-element case.
* gst/gst.h: Include gstghostpad.h.
* gst/gst.c (init_post): No more real, ghost pads.
* gst/Makefile.am: Add gstghostpad.[ch].
* check/Makefile.am:
* check/gst/gstbin.c:
* check/gst/gstghostpad.c (test_ghost_pads): Check that linking
into a bin creates ghost pads, and that the refcounts are right.
Partly moved from gstbin.c.
Original commit message from CVS:
* gst/elements/gstcapsfilter.c: (gst_capsfilter_set_property):
Free existing caps if the capsfilter changes. Add a FIXME about
setting those caps on the pads.
* gst/gstutils.c: (gst_element_get_compatible_pad), (ghost_up):
Before adding a ghost pad to a parent bin, check that there isn't
already one for the element on the bin. Prevents infinite recursion
when using decodebin in parse pipelines. Andy says he'll rewrite the
way this works anyway, so ignore the hack.
Original commit message from CVS:
* gst/base/gstbasesrc.c: (gst_basesrc_activate):
Don't go in pull mode for non-seekable sources.

(gst_type_find_element_handle_event), (find_peek),
(gst_type_find_element_chain), (do_pull_typefind),
(gst_type_find_element_change_state):
Allow typefinding (w/o seeking) in push-mode, simplified version
of what was in 0.8.
* gst/gstutils.c: (gst_buffer_join):
* gst/gstutils.h:
gst_buffer_join() from 0.8.
Original commit message from CVS:
2005-05-14 Andy Wingo <wingo@pobox.com>
* gst/gstpipeline.c (gst_pipeline_init): Drop ref on bus after
gst_element_set_bus.
(gst_pipeline_dispose): Set the bus on the pipeline to NULL. In
normal cases, this will destroy the bus.
* gst/gstutils.c (prepare_link_maybe_ghosting): Drop ref on root
object.
Original commit message from CVS:
2005-05-13 Andy Wingo <wingo@pobox.com>
* gst/gstutils.c (gst_element_link_pads): Instead of calling
gst_pad_link, call pad_link_maybe_ghosting,
(pad_link_maybe_ghosting): Links pads, making sure that the
elements being linked are in the same bin.
(find_common_root, object_has_ancestor, ghost_up, remove_pad):
Helpers for pad_link_maybe_ghosting.

(gst_element_query_convert), (intersect_caps_func),
(gst_pad_query_position), (gst_pad_query_convert):
Fix refcounting in utils function.
No point in trying to activate a pad when it's added, it could
be added from the state change function and then we deadlock, the
element has to decide what to do.
Original commit message from CVS:
Remove old query functions. Ported old code.
Added position/convert helper functions to gstutils.
Reordered gstpad.c code, grouping relevant things.
Remove gst_message_new(), always need to speficy a specific
message.

Original commit message from CVS:
* gst/elements/Makefile.am:
* gst/elements/gstcapsfilter.c: New element that acts like an
identity, but filters caps. Will eventually replace filtered
caps in pad linking.
* gst/gstutils.c: (gst_element_create_all_pads): New function
to create all the ALWAYS pads that are registered with an
element class. This functionality should eventually be
merged in with GstElement initialization.

returns immediatly instead of blocking forever)
- Moved clock get/set functions to element class instead of instance.
- Added cache methods on elements.
- Renamed GST_PROPS_BOOL_TYPE to GST_PROPS_BOOLEAN_TYPE to make it more
consistent with gst_props_get/set_boolean and GST_PROPS_BOOLEAN.

Original commit message from CVS:
- added playondemand plugin by Leif Morgan Johnson <lmjohns3@eos.ncsu.edu>
- some fixes to int2float
- aplied a patch from wrobell <wrobell@ite.pl> that is a first attempt at
making automake 1.5 happy (gst now requires automake1.5). It's still not
perfect but it builds.
- Made the schedulers plugable. The default scheduler now lives inside a
plugin.
- Added a new mpeg1/2 parser/demuxer.
- Fixed some compiler warnings in the core libs.
- substantial work to GstThread (hopefully less race conditions). simplified
the code in GstThread a bit. A state change can now also happen in the
thread context.
- reworked the state semantics of a bin. it'll now automatically get the
highest state of its children.
- the autoplugger now nests the threads so that a state change failure of
one thread doesn't make its upstream thread lock.
- GstQueue refuses to go to PLAYING if the sinkpad is not connected. This
way the queue will not wedge in the _get lock.
- GstQueue unlocks its mutexes when going to PAUSED.
- make sure that when all elements in a bin/thread go to PAUSED, the bin
is set to PAUSED too.
- make a parent bin wait for its children to PAUSE before ending the
iteration with FALSE (EOS)
- Some changes to GstPlay to deal with EOS.
- aplied the latest patch from Zeenix to gstrtp.
end result: GstPlay doesn't crash on EOS and the pipeline is now shut down
properly.
Original commit message from CVS:
API docs.
revived _buffer_ref_by_count
fast types for scheduler and bin.
error checking on plugin features;
removed some prototypes that were not implemented (gst_pipeline_iterate
comes to mind)
remove gst_pad_event until we know what it's supposed to do.
remove sinesrc, it wasn't compiles anymore, so...
updates to various elements that used the old event API.
