The idea was originally that if one passed &dest_fmt with
dest_fmt=GST_FORMAT_DEFAULT, then the code answering the query
could change dest_fmt to the actual default format used. However,
in more than half a decade of GStreamer 0.10 no piece of code in
GStreamer has ever used that feature, nor are there that many
users of this API that actually check whether the format returned
is the original format passed before using the values returned.
Also, it's just annoying-to-use API in its own right.
For all these reasons, make it so that the destination format is
passed directly and can't be changed by the element queried.
This reverts commit de29ae7b92.
Re-adds GFLOAT_TO_LE, GFLOAT_TO_BE, GDOUBLE_TO_LE, and GDOUBLE_TO_BE.
Turns out these aren't in GLib yet afer all (since we didn't
actually open a bug to get them added..)
This caused "re-declaration" problems.

Add new functions to clarify how the caps are compared to the template caps of
the element factory. Improve the docs to point out the difference.
Deprecate: gst_element_factory_can_{src|sink}_caps
API: add gst_element_factory_can_{src|sink}_{any|all}_capps
https://bugzilla.gnome.org/show_bug.cgi?id=402141
Make code including GStreamer headers compile with -Wcast-qual by
maintaining const-ness when casting. Also fix function signature of
gst_byte_writer_set_pos(): the byte writer should not be marked as
const.
https://bugzilla.gnome.org/show_bug.cgi?id=627910
And use it for the fraction comparisons in gstvalue.c instead
of using comparisons by first converting the fractions to double.
Should fix bug #628174.
API: gst_util_fraction_compare()
They are actually *not* const functions because on architectures
without int128 instructions the parameters were changed.
gcc re-used the parameters on the stack for multiple calls though
and the changed parameters were used for the second call then.
Fixes bug #623003.
Adds that warning to configure.ac
Includes a tiny change of the GST_BOILERPLATE_FULL() macro:
The get_type() function is no longer declared before being defined.

gst_event_new_sink_message()
gst_event_parse_sink_message()
This event is used for sending a GstMessage downstream and synchronized
with the stream, to be posted by the sink once it reaches the sink.
Fixes bug #602275.
gst_util_greatest_common_divisor()
gst_util_double_to_fraction()
gst_util_fraction_to_double()
Using these instead of going over GValue has much lower overhead.
Also add float<->fraction transform functions for GValue.
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.
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:
2008-11-04 Andy Wingo <wingo@pobox.com>
Add sequence numbers to events and messages. See #559250.
* gst/gstutils.c (gst_util_seqnum_next, gst_util_seqnum_compare):
New functions.
* gst/gstevent.h:
* gst/gstevent.c (_gst_event_copy, gst_event_new): Initialize new
events with a new sequence number, and copy it when copying.
(gst_event_get_seqnum, gst_event_set_seqnum): Accessors for an
event's sequence number.
* gst/gstmessage.h:
* gst/gstmessage.c (_gst_message_copy, gst_message_new_custom):
(gst_event_get_seqnum, gst_event_set_seqnum): As with events, so
with messages.
* docs/gst/gstreamer-sections.txt: Add new functions to the docs.
Original commit message from CVS:
* docs/gst/gstreamer-sections.txt:
* gst/gstutils.h:
API: Move float endianness conversion macros from libgstfloatcast
to core as it's useful in general, even in core. Fixes bug #555196.
This adds GDOUBLE_FROM_BE, GDOUBLE_FROM_LE, GDOUBLE_TO_BE,
GDOUBLE_TO_LE, GDOUBLE_SWAP_LE_BE, GFLOAT_FROM_BE, GFLOAT_FROM_LE,
GFLOAT_TO_BE, GFLOAT_TO_LE, GFLOAT_SWAP_LE_BE.
Also add GST_READ_ and GST_WRITE_ macros for floats and doubles:
GST_READ_FLOAT_LE, GST_READ_FLOAT_BE, GST_READ_DOUBLE_LE,
GST_READ_DOUBLE_BE, GST_WRITE_FLOAT_LE, GST_WRITE_FLOAT_BE,
GST_WRITE_DOUBLE_LE, GST_WRITE_DOUBLE_BE.
Original commit message from CVS:
* docs/gst/gstreamer-sections.txt:
* gst/gstutils.h:
Always use the unaligned variants of GST_READ_UINT* and GST_WRITE_UINT*
as it's too easy to break the ISO C strict aliasing rules with simple
casts to the corresponding type and this would introduce hard to debug
bugs. Fixes bug #545714.
API: Add GST_READ_UINT24_(LE|BE) and GST_WRITE_UINT24_(LE|BE).
Original commit message from CVS:
* gst/gstutils.h: (GST_BOILERPLATE_FULL):
Try to fix 'dereferencing type-punned pointer will break strict
aliasing rules' warnings with C++ compilers and GLib >= 2.14.0: GLib
changed the default GType typedef from gulong to gsize at some point,
but kept GType typedef'ed to gulong for C++ for ABI reasons; the
g_once_* functions all take a gsize * though, so work around the type
mismatch for C++ by doing everything in gsize and casting to GType
later.
