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

We need to ensure we call gst_pad_check_link() with the two pads in the correct
order. The order depends on wheter we iterate src or sink pads.

The new request_new_pad_full vmethod provides an additional caps field,
which allows elements to take better decision process.
Also, add a gst_element_request_pad() function to allow developers to be
able to specify which pad template they want a pad of.
Convert gstutils to use that new method instead of the old one when more
efficient.
This is useful for being able to request pads in a more flexible way,
especially when the element can provide pads whose caps depend on
runtime configuration and therefore can't provide pre-registered
pad templates.
API: GstElement::request_new_pad_full
API: gst_element_request_pad
https://bugzilla.gnome.org/show_bug.cgi?id=637300
Make the _get_caps functions behave like the _get_caps_reffed variants and
remove the _reffed variants. This means that _get_caps doesn't return a writable
caps anymore and an explicit _make_writable() is needed before modifying the
caps.
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()
gst_element_link_many does some magic and creates ghostpads
if needed, but it didn't set the newly created ghostpad to
active if needed. This patch fixes it.
https://bugzilla.gnome.org/show_bug.cgi?id=626784
In gst_element_get_compatible_pad(), when trying to find a compatible pad on an
element for a given pad, there's no point in checking the element's sink pads
if the pad to link is a sink pad as well, or the element's source pads if the
given pad is a source pad already, since those would never be able to link
anyway. Should speed up linking using the convenience functions a little bit,
or at least reduce debug log output.
gst_pad_proxy_getcaps() would return the pad template caps if the other side
returned empty caps or if the intersection of all the caps on the other side
was empty.
https://bugzilla.gnome.org/show_bug.cgi?id=624203
No need to call gst_element_link_pads_filtered with filter=NULL, which would
call gst_element_link_pads() in that way. Call it directly to save a call and
expensive gobject type checks.
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.
In most places in core and baseclasses we just need the caps to do caps-
intersections. In that case ref'ed caps are enough (no need to copy).
This patch also switches the code to use the new functions.
API: gst_pad_get_caps_refed(), gst_pad_peer_get_caps_refed()
This is available in newer gcc releases and it should only exist
on platforms that provide some native 128bit integer arithmetic
instructions.
The x86-64 assembly for this is still kept for non-gcc compilers
that don't provide __uint128_t magic.
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.
