static

std::vector< Glib::RefPtr<DiscovererStreamInfo> > Gst::DiscovererInfo::get_audio_streams ( )

Finds all the Gst::DiscovererAudioInfo contained in info.

Returns: A List of matching Gst::DiscovererStreamInfo. The caller should free it with stream_info_list_free().

std::vector< Glib::RefPtr<const DiscovererStreamInfo> > Gst::DiscovererInfo::get_audio_streams ( ) const

Finds all the Gst::DiscovererAudioInfo contained in info.

Returns: A List of matching Gst::DiscovererStreamInfo. The caller should free it with stream_info_list_free().

std::vector< Glib::RefPtr<DiscovererStreamInfo> > Gst::DiscovererInfo::get_container_streams ( )

Finds all the Gst::DiscovererContainerInfo contained in info.

Returns: A List of matching Gst::DiscovererStreamInfo. The caller should free it with stream_info_list_free().

std::vector< Glib::RefPtr<const DiscovererStreamInfo> > Gst::DiscovererInfo::get_container_streams ( ) const

Finds all the Gst::DiscovererContainerInfo contained in info.

Returns: A List of matching Gst::DiscovererStreamInfo. The caller should free it with stream_info_list_free().

ClockTime Gst::DiscovererInfo::get_duration ( ) const

Returns: The duration of the URI in Gst::ClockTime (nanoseconds).

Structure Gst::DiscovererInfo::get_misc ( ) const

Returns: Miscellaneous information stored as a Gst::Structure (for example: information about missing plugins). If you wish to use the Gst::Structure after the life-time of info, you will need to copy it.

DiscovererResult Gst::DiscovererInfo::get_result ( ) const

Returns: The result of the discovery as a Gst::DiscovererResult.

bool Gst::DiscovererInfo::get_seekable ( ) const

Returns: The whether the URI is seekable.

Glib::RefPtr<DiscovererStreamInfo> Gst::DiscovererInfo::get_stream_info ( )

Returns: The structure (or topology) of the URI as a Gst::DiscovererStreamInfo. This structure can be traversed to see the original hierarchy. Unref with gst_discoverer_stream_info_unref() after usage.

Glib::RefPtr<const DiscovererStreamInfo> Gst::DiscovererInfo::get_stream_info ( ) const

Returns: The structure (or topology) of the URI as a Gst::DiscovererStreamInfo. This structure can be traversed to see the original hierarchy. Unref with gst_discoverer_stream_info_unref() after usage.

std::vector< Glib::RefPtr<DiscovererStreamInfo> > Gst::DiscovererInfo::get_stream_list ( )

Returns: The list of all streams contained in the #info. Free after usage with stream_info_list_free().

std::vector< Glib::RefPtr<const DiscovererStreamInfo> > Gst::DiscovererInfo::get_stream_list ( ) const

Returns: The list of all streams contained in the #info. Free after usage with stream_info_list_free().

std::vector< Glib::RefPtr<DiscovererStreamInfo> > Gst::DiscovererInfo::get_streams ( GType streamtype )

Finds the Gst::DiscovererStreamInfo contained in info that match the given streamtype.

Parameters

streamtype A Type derived from Gst::DiscovererStreamInfo.

Returns: A List of matching Gst::DiscovererStreamInfo. The caller should free it with stream_info_list_free().

std::vector< Glib::RefPtr<const DiscovererStreamInfo> > Gst::DiscovererInfo::get_streams ( GType streamtype ) const

Finds the Gst::DiscovererStreamInfo contained in info that match the given streamtype.

Parameters

streamtype A Type derived from Gst::DiscovererStreamInfo.

Returns: A List of matching Gst::DiscovererStreamInfo. The caller should free it with stream_info_list_free().

TagList Gst::DiscovererInfo::get_tags ( ) const

Returns: All tags contained in the URI. If you wish to use the tags after the life-time of info, you will need to copy them.

Glib::ustring Gst::DiscovererInfo::get_uri ( ) const

Returns: The URI to which this information corresponds to. Copy it if you wish to use it after the life-time of info.

std::vector< Glib::RefPtr<DiscovererStreamInfo> > Gst::DiscovererInfo::get_video_streams ( )

Finds all the Gst::DiscovererVideoInfo contained in info.

Returns: A List of matching Gst::DiscovererStreamInfo. The caller should free it with stream_info_list_free().

std::vector< Glib::RefPtr<const DiscovererStreamInfo> > Gst::DiscovererInfo::get_video_streams ( ) const

Finds all the Gst::DiscovererVideoInfo contained in info.

Returns: A List of matching Gst::DiscovererStreamInfo. The caller should free it with stream_info_list_free().

GstDiscovererInfo* Gst::DiscovererInfo::gobj ( )

Provides access to the underlying C instance.

const GstDiscovererInfo* Gst::DiscovererInfo::gobj ( ) const

Provides access to the underlying C instance.

GstDiscovererInfo* Gst::DiscovererInfo::gobj_copy ( ) const

		std::size_t
	)

protected

void Gst::DiscovererInfo::reference ( ) const

Increment the reference count for this object.

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

void Gst::DiscovererInfo::unreference ( ) const

Decrement the reference count for this object.

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

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

A Glib::wrap() method for this object.

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.
