See create() for more details.

Member Function Documentation

◆ create()

static Glib::RefPtr<Gst::QueryUri> Gst::QueryUri::create ( )
static

Constructs a new query URI query object.

Use gst_query_unref() when done with it. An URI query is used to query the current URI that is used by the source or sink.

Returns
a new Gst::Query.

◆ parse()

Glib::ustring Gst::QueryUri::parse ( ) const

Parse an URI query, writing the URI into uri as a newly allocated string, if the respective parameters are non-NULL.

Free the string with g_free() after usage.

Returns
the storage for the current URI.

◆ parse_uri_redirection()

Glib::ustring Gst::QueryUri::parse_uri_redirection ( ) const

Parse an URI query, return URI, if the respective parameters.

Returns
the storage for the redirect URI (may be empty).

◆ set()

void Gst::QueryUri::set ( const Glib::ustring &  uri)

Answer a URI query by setting the requested URI.

Parameters
urithe URI to set.

◆ set_uri_redirection()

void Gst::QueryUri::set_uri_redirection ( const Glib::ustring &  uri)

Answer a URI query by setting the requested URI redirection.

Parameters
urithe URI to set.
