|
|
|
* Caps (capabilities) are lighweight refcounted objects describing media types.
|
2005-11-09 12:01:46 +00:00
|
|
|
* They are composed of an array of #GstStructure.
|
|
|
|
*
|
|
|
|
* Caps are exposed on #GstPadTemplate to describe all possible types a
|
2007-02-13 09:10:53 +00:00
|
|
|
* given pad can handle. They are also stored in the #GstRegistry along with
|
|
|
|
* a description of the #GstElement.
|
2005-11-09 12:01:46 +00:00
|
|
|
*
|
2006-07-02 12:54:03 +00:00
|
|
|
* Caps are exposed on the element pads using the gst_pad_get_caps() pad
|
|
|
|
* function. This function describes the possible types that the pad can
|
2005-11-18 16:04:28 +00:00
|
|
|
* handle or produce at runtime.
|
2005-11-09 12:01:46 +00:00
|
|
|
*
|
|
|
|
* Caps are also attached to buffers to describe to content of the data
|
|
|
|
* pointed to by the buffer with gst_buffer_set_caps(). Caps attached to
|
|
|
|
* a #GstBuffer allow for format negotiation upstream and downstream.
|
|
|
|
*
|
|
|
|
* A #GstCaps can be constructed with the following code fragment:
|
|
|
|
*
|
|
|
|
* <example>

|
|
* <title>Creating caps</title>
|

* caps = gst_caps_new_simple ("video/x-raw-yuv",
|
|
|
|
* "format", GST_TYPE_FOURCC, GST_MAKE_FOURCC ('I', '4', '2', '0'),
|
2007-02-13 09:10:53 +00:00
|
|
|
* "framerate", GST_TYPE_FRACTION, 25, 1,
|
2005-11-09 12:01:46 +00:00
|
|
|
* "pixel-aspect-ratio", GST_TYPE_FRACTION, 1, 1,
|
2006-07-02 12:54:03 +00:00
|
|
|
* "width", G_TYPE_INT, 320,
|
|
|
|
* "height", G_TYPE_INT, 240,
|
2005-11-09 12:01:46 +00:00
|
|
|
* NULL);
|
|
|
|
* </programlisting>
|
|
|
|
* </example>
|
|
|
|
*
|
|
|
|
* A #GstCaps is fixed when it has no properties with ranges or lists. Use
|
|
|
|
* gst_caps_is_fixed() to test for fixed caps. Only fixed caps can be
|
|
|
|
* set on a #GstPad or #GstBuffer.
|
|
|
|
*
|
2005-11-18 16:04:28 +00:00
|
|
|
* Various methods exist to work with the media types such as subtracting
|
2005-11-09 12:01:46 +00:00
|
|
|
* or intersecting.

gst/gstcaps.c: Callgrind micro optimisations.

(gst_caps_to_string):
Callgrind micro optimisations.
Avoid array bounds checks and force inline of trivial function.
* gst/gstobject.c: (gst_object_set_name_default):
-1 is equivalent to letting glib to the strlen but then there is more
room for optimisations and it's not our fault.
* gst/gststructure.c: (gst_structure_id_empty_new_with_size):
no need to clear the array, we're cool.
* gst/gstvalue.c: (gst_type_is_fixed), (gst_value_is_fixed):
The most common _is_fixed() check is done on fundamental glib base
types so we check this first instead of doing a huge amount of
useless GST_TYPE_ARRAY calls.

* gst/gstcaps.c: (gst_caps_from_string_inplace):
fix bug when converting from empty string.
* gst/gstcaps.c: (gst_caps_new_any), (gst_caps_new_simple),
(gst_caps_new_full_valist), (gst_caps_copy), (gst_caps_copy_1):
use gst_caps_new_empty to allocate a new caps. Only that function
allocates memory for caps now.
* gst/gstcaps.c: (gst_caps_remove_and_get_structure),
(gst_caps_remove_structure):
add ability to remove one structure (but not to header yet)
* gst/gstcaps.c: (gst_caps_compare_structures),
(gst_caps_simplify), (gst_caps_structure_figure_out_union),
(gst_caps_structure_simplify), (gst_caps_do_simplify),
* gst/gstcaps.h:
add gst_caps_do_simplify that tries to simplify a caps in place.
Deprecate old gst_caps_simplify function.
* testsuite/caps/caps.h:
add caps.h containing a common set of caps to test against.
* testsuite/caps/sets.c: (check_caps), (main):
use it.
* testsuite/caps/.cvsignore:
* testsuite/caps/Makefile.am:
* testsuite/caps/simplify.c: (check_caps), (main):
add test to check correctness and efficency of caps simplification.

-1 is equivalent to letting glib to the strlen but then there is more

no need to clear the array, we're cool.

tests/network-clock.scm: Commentary update.
Original commit message from CVS:
2005-07-01 Andy Wingo <wingo@pobox.com>
* tests/network-clock.scm: Commentary update.
* gst/elements/gstidentity.c (PROP_DUPLICATE): Gone daddy gone.
Didn't really make sense, not implementable with basetransform,
etc.
(gst_identity_transform): Unref inbuf via make_writable. Feeble
attempt at implementing the sync property, needs an unlock method.
* gst/base/gstbasetransform.c (gst_base_transform_transform_caps):
New func, by default returns the same caps (the identity
transformation).
(gst_base_transform_getcaps): Uses transform_caps to return
something sensible.
(gst_base_transform_setcaps): Complicated logic to get caps on
both pads, even if they are different, and to call set_caps once
for every time both pads get their caps set.
(gst_base_transform_handle_buffer): Give the ref to the transform
function. Allows in-place modification of the buffer.
* gst/base/gstbasetransform.h (transform_caps): New class method.
Given caps on one side, what can I do on the other.
(set_caps): Take two caps, one for each side of the element.
* gst/gstpad.h:
* gst/gstpad.c (gst_pad_fixate_caps): Change prototype to modify
caps in place. This is safe because we can check the mutability of
the caps, and a good idea because fixate functions are just called
as a matter of last resort. (Not actually implemented.)
(gst_pad_set_caps): If the caps we're setting is actually the same
as the existing pad caps, just update the pointer without calling
setcaps. Assert that caps is either NULL or fixed, as per the
docs.
* gst/gstghostpad.c: Update for fixate changes.

Callgrind micro optimisations.
Avoid array bounds checks and force inline of trivial function.
* gst/gstobject.c: (gst_object_set_name_default):
-1 is equivalent to letting glib to the strlen but then there is more
room for optimisations and it's not our fault.

no need to clear the array, we're cool.
* gst/gstvalue.c: (gst_type_is_fixed), (gst_value_is_fixed):
The most common _is_fixed() check is done on fundamental glib base
types so we check this first instead of doing a huge amount of
useless GST_TYPE_ARRAY calls.

gst/gstcaps.c: Callgrind micro optimisations.

(gst_caps_copy_nth), (gst_caps_set_simple),

(gst_caps_is_equal_fixed), (gst_caps_intersect),
(gst_caps_subtract), (gst_caps_normalize), (gst_caps_do_simplify),
(gst_caps_to_string):
Callgrind micro optimisations.
Avoid array bounds checks and force inline of trivial function.
* gst/gstobject.c: (gst_object_set_name_default):
-1 is equivalent to letting glib to the strlen but then there is more
room for optimisations and it's not our fault.
* gst/gststructure.c: (gst_structure_id_empty_new_with_size):
no need to clear the array, we're cool.
* gst/gstvalue.c: (gst_type_is_fixed), (gst_value_is_fixed):
The most common _is_fixed() check is done on fundamental glib base
types so we check this first instead of doing a huge amount of
useless GST_TYPE_ARRAY calls.

use gst_caps_new_empty to allocate a new caps. Only that function
allocates memory for caps now.

Callgrind micro optimisations.
Avoid array bounds checks and force inline of trivial function.
* gst/gstobject.c: (gst_object_set_name_default):
-1 is equivalent to letting glib to the strlen but then there is more
room for optimisations and it's not our fault.
* gst/gststructure.c: (gst_structure_id_empty_new_with_size):
no need to clear the array, we're cool.
* gst/gstvalue.c: (gst_type_is_fixed), (gst_value_is_fixed):
The most common _is_fixed() check is done on fundamental glib base
types so we check this first instead of doing a huge amount of
useless GST_TYPE_ARRAY calls.

(gst_caps_copy_nth), (gst_caps_set_simple),

(gst_caps_to_string):
Callgrind micro optimisations.
Avoid array bounds checks and force inline of trivial function.
* gst/gstobject.c: (gst_object_set_name_default):
-1 is equivalent to letting glib to the strlen but then there is more
room for optimisations and it's not our fault.
* gst/gststructure.c: (gst_structure_id_empty_new_with_size):
no need to clear the array, we're cool.
* gst/gstvalue.c: (gst_type_is_fixed), (gst_value_is_fixed):
The most common _is_fixed() check is done on fundamental glib base
types so we check this first instead of doing a huge amount of
useless GST_TYPE_ARRAY calls.

(gst_caps_to_string):
Callgrind micro optimisations.
Avoid array bounds checks and force inline of trivial function.
* gst/gstobject.c: (gst_object_set_name_default):
-1 is equivalent to letting glib to the strlen but then there is more
room for optimisations and it's not our fault.
* gst/gststructure.c: (gst_structure_id_empty_new_with_size):
no need to clear the array, we're cool.
* gst/gstvalue.c: (gst_type_is_fixed), (gst_value_is_fixed):
The most common _is_fixed() check is done on fundamental glib base
types so we check this first instead of doing a huge amount of
useless GST_TYPE_ARRAY calls.

gst/gstcaps.c: Callgrind micro optimisations.
Original commit message from CVS:
* gst/gstcaps.c: (gst_caps_copy), (_gst_caps_free),
(gst_caps_merge_structure), (gst_caps_get_structure),
(gst_caps_copy_nth), (gst_caps_set_simple),
(gst_caps_set_simple_valist), (gst_caps_is_fixed),
(gst_caps_is_equal_fixed), (gst_caps_intersect),
(gst_caps_subtract), (gst_caps_normalize), (gst_caps_do_simplify),
(gst_caps_to_string):
Callgrind micro optimisations.
Avoid array bounds checks and force inline of trivial function.
* gst/gstobject.c: (gst_object_set_name_default):
-1 is equivalent to letting glib to the strlen but then there is more
room for optimisations and it's not our fault.
* gst/gststructure.c: (gst_structure_id_empty_new_with_size):
no need to clear the array, we're cool.
* gst/gstvalue.c: (gst_type_is_fixed), (gst_value_is_fixed):
The most common _is_fixed() check is done on fundamental glib base
types so we check this first instead of doing a huge amount of
useless GST_TYPE_ARRAY calls.

* gst/gstcaps.c: (gst_caps_new_any), (gst_caps_new_simple),
(gst_caps_new_full_valist), (gst_caps_copy), (gst_caps_copy_1):
use gst_caps_new_empty to allocate a new caps. Only that function

add gst_caps_do_simplify that tries to simplify a caps in place.
Deprecate old gst_caps_simplify function.
* testsuite/caps/caps.h:
add caps.h containing a common set of caps to test against.
* testsuite/caps/sets.c: (check_caps), (main):
use it.

gst/gstcaps.c: Callgrind micro optimisations.
Original commit message from CVS:

(gst_caps_merge_structure), (gst_caps_get_structure),
(gst_caps_copy_nth), (gst_caps_set_simple),

(gst_caps_is_equal_fixed), (gst_caps_intersect),
(gst_caps_subtract), (gst_caps_normalize), (gst_caps_do_simplify),
(gst_caps_to_string):
Callgrind micro optimisations.
Avoid array bounds checks and force inline of trivial function.
* gst/gstobject.c: (gst_object_set_name_default):
-1 is equivalent to letting glib to the strlen but then there is more
room for optimisations and it's not our fault.
* gst/gststructure.c: (gst_structure_id_empty_new_with_size):
no need to clear the array, we're cool.
* gst/gstvalue.c: (gst_type_is_fixed), (gst_value_is_fixed):
The most common _is_fixed() check is done on fundamental glib base
types so we check this first instead of doing a huge amount of
useless GST_TYPE_ARRAY calls.

gst/gstcaps.c: fix bug when converting from empty string.
Original commit message from CVS:
* gst/gstcaps.c: (gst_caps_from_string_inplace):
fix bug when converting from empty string.
* gst/gstcaps.c: (gst_caps_new_any), (gst_caps_new_simple),
(gst_caps_new_full_valist), (gst_caps_copy), (gst_caps_copy_1):
use gst_caps_new_empty to allocate a new caps. Only that function
allocates memory for caps now.
* gst/gstcaps.c: (gst_caps_remove_and_get_structure),
(gst_caps_remove_structure):
add ability to remove one structure (but not to header yet)
* gst/gstcaps.c: (gst_caps_compare_structures),
(gst_caps_simplify), (gst_caps_structure_figure_out_union),
(gst_caps_structure_simplify), (gst_caps_do_simplify),
* gst/gstcaps.h:
add gst_caps_do_simplify that tries to simplify a caps in place.
Deprecate old gst_caps_simplify function.
* testsuite/caps/caps.h:
add caps.h containing a common set of caps to test against.
* testsuite/caps/sets.c: (check_caps), (main):
use it.
* testsuite/caps/.cvsignore:
* testsuite/caps/Makefile.am:
* testsuite/caps/simplify.c: (check_caps), (main):
add test to check correctness and efficency of caps simplification.
