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.
Original commit message from CVS:
* gst/gstutils.c:
* gst/gstutils.h:
API: Deprecate gst_atomic_int_set(), g_atomic_int_set() should be used
now that we depend on new enough GLib.

(gst_base_sink_set_qos_enabled):

(gst_net_time_provider_set_property):
Use g_atomic_int_set() instead of gst_atomic_int_set().

* win32/common/libgstreamer.def:
Add gst_pad_add_*_probe_full() functions with a notify callback that
lets the caller free the data it passes to the probe functions. This
is useful for bindings such as gst-python or gstreamermm (#526814).
API: gst_pad_add_data_probe_full
API: gst_pad_add_buffer_probe_full
API: gst_pad_add_event_probe_full
* tests/check/gst/gstutils.c:
Add minimal unit test to make sure freeing the data actually works
as expected.
* tests/benchmarks/.cvsignore:
Random cvsignore addendum.

been disabled (#342564).

Original commit message from CVS:
* gst/gstutils.h:
Add G_UNLIKELY to our boilerplate to optimise the 'already registered
the type' case. (Closes: #335195 for now). In the future, when we
depend on GLib 2.10, we could also intern the type name using
g_intern_static_string()

Make things work with --disable-parse as they do with

gstconfig.h

Bundling query position/duration is not a good idea since duration

is.
