Detailed Description

DiscovererStreamInfo - Base class for information concerning a media stream.

Depending on the stream type, one can find more media-specific information in Gst::DiscovererAudioInfo, Gst::DiscovererVideoInfo, and Gst::DiscovererContainerInfo.

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

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

Member Function Documentation

◆ get_caps() [1/2]

Glib::RefPtr<Gst::Caps> Gst::DiscovererStreamInfo::get_caps ( )

Returns: The Gst::Caps of the stream. Unref with #gst_caps_unref after usage.

◆ get_caps() [2/2]

Glib::RefPtr<const Gst::Caps> Gst::DiscovererStreamInfo::get_caps ( ) const

Returns: The Gst::Caps of the stream. Unref with #gst_caps_unref after usage.

◆ get_misc()

Structure Gst::DiscovererStreamInfo::get_misc ( ) const

Deprecated: This functions is deprecated since version 1.4, use #gst_discoverer_info_get_missing_elements_installer_details.

Returns: Additional information regarding the stream (for example codec version, profile, etc..). If you wish to use the Gst::Structure after the life-time of info you will need to copy it.

◆ get_next() [1/2]

Glib::RefPtr<Gst::DiscovererStreamInfo> Gst::DiscovererStreamInfo::get_next ( )

Returns: The next Gst::DiscovererStreamInfo in a chain. nullptr for final streams. Unref with #gst_discoverer_stream_info_unref after usage.

◆ get_next() [2/2]

Glib::RefPtr<const Gst::DiscovererStreamInfo> Gst::DiscovererStreamInfo::get_next ( ) const

Returns: The next Gst::DiscovererStreamInfo in a chain. nullptr for final streams. Unref with #gst_discoverer_stream_info_unref after usage.

◆ get_previous() [1/2]

Glib::RefPtr<Gst::DiscovererStreamInfo> Gst::DiscovererStreamInfo::get_previous ( )

Returns: The previous Gst::DiscovererStreamInfo in a chain. nullptr for starting points. Unref with #gst_discoverer_stream_info_unref after usage.

◆ get_previous() [2/2]

Glib::RefPtr<Gst::DiscovererStreamInfo> Gst::DiscovererStreamInfo::get_previous ( ) const

Returns: The previous Gst::DiscovererStreamInfo in a chain. nullptr for starting points. Unref with #gst_discoverer_stream_info_unref after usage.

◆ get_stream_id()

Glib::ustring Gst::DiscovererStreamInfo::get_stream_id ( ) const

Returns: The stream ID of this stream. If you wish to use the stream ID after the life-time of info you will need to copy it.

◆ get_stream_type_nick()

Glib::ustring Gst::DiscovererStreamInfo::get_stream_type_nick ( ) const

Returns: A human readable name for the stream type of the given info (ex : "audio", "container",...).

◆ get_tags()

Gst::TagList Gst::DiscovererStreamInfo::get_tags ( ) const

Returns: The tags contained in this stream. If you wish to use the tags after the life-time of info you will need to copy them.

◆ get_toc()

Glib::RefPtr<const Gst::Toc> Gst::DiscovererStreamInfo::get_toc ( ) const

Returns: The TOC contained in this stream. If you wish to use the TOC after the life-time of info you will need to copy it.

◆ gobj() [1/2]

GstDiscovererStreamInfo* Gst::DiscovererStreamInfo::gobj ( )

Provides access to the underlying C instance.

◆ gobj() [2/2]

const GstDiscovererStreamInfo* Gst::DiscovererStreamInfo::gobj ( ) const

Provides access to the underlying C instance.

◆ gobj_copy()

GstDiscovererStreamInfo* Gst::DiscovererStreamInfo::gobj_copy ( ) const

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

◆ operator delete()

void Gst::DiscovererStreamInfo::operator delete	(	void *	,
		std::size_t
	)

protected

◆ operator=()

DiscovererStreamInfo& Gst::DiscovererStreamInfo::operator= ( const DiscovererStreamInfo& )

delete

◆ reference()

void Gst::DiscovererStreamInfo::reference ( ) const

Increment the reference count for this object.

You should never need to do this manually - use the object via a RefPtr instead.

◆ unreference()

void Gst::DiscovererStreamInfo::unreference ( ) const

Decrement the reference count for this object.

You should never need to do this manually - use the object via a RefPtr instead.

◆ wrap()

Glib::RefPtr< Gst::DiscovererStreamInfo > wrap	(	GstDiscovererStreamInfo *	object,
		bool	take_copy = `false`
	)

Parameters

object	The C instance.
take_copy	False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns: A C++ instance that wraps this C instance.
