And turn overflow checks from assertions into simple checks to
return FALSE.

72c512a87d utils: use reffed _get_caps() version 
We don't need to have a writable copy so we can use the _reffed
version instead.

d60a3b8a59 gstreamer: remove unneeded casts 
G_PARAM_SPEC_VALUE_TYPE does an expensive type check, whereas the
value_type field is a public field, so we can just use it directly.

3c09381cef utils: defer getting the classes until we actualy need them 
This function has a lot of early returns. Give them soem more benefit.

5fa9d942e3 utils: avoid extra hop in gst_element_link 
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.

c6f2a94777 utils: fix proxy_getcaps 
Make it return the padtemplate caps on errors and no parent.
Only intersect pads of the oposite direction of the source pad.

0ed24bc50e utils: API: Add multiplication and addition functions for fractions 
gst_util_fraction_add()
gst_util_fraction_multiply()

These work on plain integers instead of GValues to
keep the overhead as low as possible.
 2009-11-16 09:56:32 +01:00
Sebastian Dröge
e4257e8d5f gstutils: API: Add fraction helper functions 
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.

f63ecd04a8 pad: rename new api from _refed to _reffed. 
Due to popular demand rename the new api as we still can.

fcc5d783df pad: add variants of gst_pad_get_caps() that don't copy caps. Fixes #590941 
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()

201cbbdce0 pad: flip the G_UNLIKELY

82526701f0 pad: don't intersect with any in proxy_pad_get_caps 
We initialize the caps with any and if a pad has NULL caps, just skip it instead
of intersecting with any. Also add branch prediction here.

8d1aeeb2af utils: Use gcc's __uint128_t for 64bit unsigned integer scaling 
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.

b0c1ebbd08 utils: use 128bits division on x86_64 2009-08-31 11:45:17 +02:00
Wim Taymans
378b1e30e7 utils: use shift instead of division 
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.

d8911f269f utils: optimize for x86_64 with some inline asm 
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.

9cfd9f9374 gstutils: API: Add rounding to nearest and next integer versions of the 64 bit integer scaling functions 
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.

f44204c8fa utils: gst_util_uint64_scale*() micro-optimisations

db6f445620 Revert "element: Set the originating pad as message source in gst_element_found_tags_for_pad ()" 
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.
