Struct gstreamer_gl::GLBufferPool

pub struct GLBufferPool { /* private fields */ }

a GLBufferPool is an object that allocates buffers with GLBaseMemory

A GLBufferPool is created with new()

GLBufferPool implements the VideoMeta buffer pool option GST_BUFFER_POOL_OPTION_VIDEO_META, the VideoAligment buffer pool option GST_BUFFER_POOL_OPTION_VIDEO_ALIGNMENT as well as the OpenGL specific BUFFER_POOL_OPTION_GL_SYNC_META buffer pool option.

Implements

GLBufferPoolExt, gst::prelude::BufferPoolExt, gst::prelude::ObjectExt, [trait@glib::ObjectExt]

GLib type: GObject with reference counted clone semantics.

Implementations

impl GLBufferPool

pub const NONE: Option<&'static GLBufferPool> = None

pub fn new(context: &impl IsA<GLContext>) -> GLBufferPool

context

the GLContext to use

Returns

a gst::BufferPool that allocates buffers with GLMemory

Trait Implementations

impl Clone for GLBufferPool

fn clone(&self) -> Self

Makes a clone of this shared reference.

This increments the strong reference count of the object. Dropping the object will decrement it again.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for GLBufferPool

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl HasParamSpec for GLBufferPool

type ParamSpec = ParamSpecObject

type SetValue = GLBufferPool

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(_: &str) -> ParamSpecObjectBuilder<'_, GLBufferPool>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for GLBufferPool

fn hash<H>(&self, state: &mut H)

where H: Hasher,

Hashes the memory address of this object.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for GLBufferPool

fn cmp(&self, other: &Self) -> Ordering

Comparison for two GObjects.

Compares the memory addresses of the provided objects.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl ParentClassIs for GLBufferPool

type Parent = BufferPool

impl<OT: ObjectType> PartialEq<OT> for GLBufferPool

fn eq(&self, other: &OT) -> bool

Equality for two GObjects.

Two GObjects are equal if their memory addresses are equal.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<OT: ObjectType> PartialOrd<OT> for GLBufferPool

fn partial_cmp(&self, other: &OT) -> Option<Ordering>

Partial comparison for two GObjects.

Compares the memory addresses of the provided objects.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl StaticType for GLBufferPool

fn static_type() -> Type

Returns the type identifier of Self.
