[src]
pub fn new_empty() -> Self
[src]
Creates a new Caps
that is empty. That is, the returned
Caps
contains no media formats.
The Caps
is guaranteed to be writable.
Caller is responsible for unreffing the returned caps.
Returns
the new Caps
pub fn new_any() -> Self
[src]
pub fn new_simple(name: &str, values: &[(&str, &dyn ToSendValue)]) -> Self
[src]
Creates a new Caps
that contains one Structure
. The
structure is defined by the arguments, which have the same format
as Structure::new
.
Caller is responsible for unreffing the returned caps.
media_type
the media type of the structure
fieldname
first field to set
Returns
the new Caps
pub fn from_iter<'a, I>(iter: I) -> Self where
I: IntoIterator<Item = &'a StructureRef>,
[src]
I: IntoIterator<Item = &'a StructureRef>,
pub fn from_iter_with_features<'a, 'b, I>(iter: I) -> Self where
I: IntoIterator<Item = (&'a StructureRef, &'b CapsFeaturesRef)>,
[src]
I: IntoIterator<Item = (&'a StructureRef, &'b CapsFeaturesRef)>,
pub fn fixate(&mut self)
[src]
Modifies the given self
into a representation with only fixed
values. First the caps will be truncated and then the first structure will be
fixated with Structure::fixate
.
This function takes ownership of self
and will call gst_caps_make_writable
on it so you must not use self
afterwards unless you keep an additional
reference to it with Caps::ref
.
Note that it is not guaranteed that the returned caps have exactly one
structure. If self
are empty caps then then returned caps will be
the empty too and contain no structure at all.
Calling this function with any caps is not allowed.
Returns
the fixated caps
pub fn merge(&mut self, other: Self)
[src]
Appends the structures contained in caps2
to self
if they are not yet
expressed by self
. The structures in caps2
are not copied -- they are
transferred to a writable copy of self
, and then caps2
is freed.
If either caps is ANY, the resulting caps will be ANY.
caps2
the Caps
to merge in
Returns
the merged caps.
pub fn merge_structure(&mut self, structure: Structure)
[src]
Appends structure
to self
if its not already expressed by self
.
structure
the Structure
to merge
Returns
the merged caps.
pub fn merge_structure_full(
&mut self,
structure: Structure,
features: Option<CapsFeatures>
)
[src]
&mut self,
structure: Structure,
features: Option<CapsFeatures>
)
Appends structure
with features
to self
if its not already expressed by self
.
structure
the Structure
to merge
features
the CapsFeatures
to merge
Returns
the merged caps.
pub fn normalize(&mut self)
[src]
Returns a Caps
that represents the same set of formats as
self
, but contains no lists. Each list is expanded into separate
GstStructures
.
This function takes ownership of self
and will call gst_caps_make_writable
on it so you must not use self
afterwards unless you keep an additional
reference to it with Caps::ref
.
Returns
the normalized Caps
pub fn simplify(&mut self)
[src]
Converts the given self
into a representation that represents the
same set of formats, but in a simpler form. Component structures that are
identical are merged. Component structures that have values that can be
merged are also merged.
This function takes ownership of self
and will call gst_caps_make_writable
on it if necessary, so you must not use self
afterwards unless you keep an
additional reference to it with Caps::ref
.
This method does not preserve the original order of self
.
Returns
The simplified caps.
pub fn truncate(&mut self)
[src]
Discard all but the first structure from self
. Useful when
fixating.
This function takes ownership of self
and will call gst_caps_make_writable
on it if necessary, so you must not use self
afterwards unless you keep an
additional reference to it with Caps::ref
.
Note that it is not guaranteed that the returned caps have exactly one
structure. If self
is any or empty caps then then returned caps will be
the same and contain no structure at all.
Returns
truncated caps
