Struct gstreamer_pbutils::DiscovererStreamInfo

#[repr(transparent)]
pub struct DiscovererStreamInfo { /* private fields */ }

Base structure for information concerning a media stream. Depending on the stream type, one can find more media-specific information in DiscovererAudioInfo, DiscovererVideoInfo, and DiscovererContainerInfo.

The DiscovererStreamInfo represents the topology of the stream. Siblings can be iterated over with DiscovererStreamInfoExt::next() and DiscovererStreamInfoExt::previous(). Children (sub-streams) of a stream can be accessed using the DiscovererContainerInfo API.

As a simple example, if you run Discoverer on an AVI file with one audio and one video stream, you will get a DiscovererContainerInfo corresponding to the AVI container, which in turn will have a DiscovererAudioInfo sub-stream and a DiscovererVideoInfo sub-stream for the audio and video streams respectively.

Trait Implementations

impl Clone for DiscovererStreamInfo

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DiscovererStreamInfo

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

Formats the value using the given formatter.

impl HasParamSpec for DiscovererStreamInfo

type ParamSpec = ParamSpecObject

type SetValue = DiscovererStreamInfo

impl Ord for DiscovererStreamInfo

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

impl ParentClassIs for DiscovererStreamInfo

type Parent = Object

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

fn eq(&self, other: &OT) -> 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<OT: ObjectType> PartialOrd<OT> for DiscovererStreamInfo

fn partial_cmp(&self, other: &OT) -> 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.
