Struct gstreamer_mpegts::Section

pub struct Section { /* private fields */ }

Generic usage of sections with GstMpegtsSection

The GstMpegtsSection object is the representation of MPEG-TS Section (SI or PSI).

Various elements can post those on the bus via GstMessage of type GST_MESSAGE_ELEMENT. The gst_message_parse_mpegts_section() function provides access to the section.

Applications (or other elements) can create them either by using one of the gst_mpegts_section_from_* functions, or by providing the raw SI data via gst_mpegts_section_new().

Elements outputting MPEG-TS streams can also create sections using the various convenience functions and then get the packetized data (to be inserted in MPEG-TS packets) using gst_mpegts_section_packetize().

For more details, refer to the ITU H.222.0 or ISO/IEC 13818-1 specifications and other specifications mentioned in the documentation.

Supported base MPEG-TS sections

These are the sections for which parsing and packetizing code exists.

Implementations

impl Section

pub fn as_ptr(&self) -> *mut GstMpegtsSection

Return the inner pointer to the underlying C value.

pub unsafe fn from_glib_ptr_borrow(ptr: &*mut GstMpegtsSection) -> &Self

Borrows the underlying C value.

pub unsafe fn from_glib_ptr_borrow_mut( ptr: &mut *mut GstMpegtsSection, ) -> &mut Self

Borrows the underlying C value mutably.

impl Section

pub fn data(&mut self) -> Bytes

Gets the original unparsed section data.

Returns

The original unparsed section data.

Trait Implementations

impl Clone for Section

fn clone(&self) -> Self

Copies the boxed type with the type-specific copy function.

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

Performs copy-assignment from source.

impl Debug for Section

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

Formats the value using the given formatter.

impl From<Section> for Value

fn from(o: Section) -> Self

Converts to this type from the input type.

impl HasParamSpec for Section

type ParamSpec = ParamSpecBoxed

type SetValue = Section

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

type BuilderFn = fn(_: &str) -> ParamSpecBoxedBuilder<'_, Section>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for Section

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

Feeds this value into the given Hasher.

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 Section

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

This method returns an Ordering between self and other.

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 PartialEq for Section

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

This method tests for self and other values to be equal, and is used by ==.

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 PartialOrd for Section

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

This method returns an ordering between self and other values if one exists.

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 Section

fn static_type() -> Type

Returns the type identifier of Self.

impl Eq for Section

impl Send for Section

impl StructuralPartialEq for Section

impl Sync for Section
