gstpbutils.discoverer

Module for [Discoverer] class

class Discoverer DiscovererGidBuilder DiscovererGidBuilderImpl

Types 3

classDiscoverer : gobject.object.ObjectWrap

The #GstDiscoverer is a utility object which allows to get as much information as possible from one or many URIs.

It provides two APIs, allowing usage in blocking or non-blocking mode.

The blocking mode just requires calling [gstpbutils.discoverer.Discoverer.discoverUri] with the URI one wishes to discover.

The non-blocking mode requires a running #GMainLoop iterating a #GMainContext, where one connects to the various signals, appends the URIs to be processed (through [gstpbutils.discoverer.Discoverer.discoverUriAsync]) and then asks for the discovery to begin (through [gstpbutils.discoverer.Discoverer.start]). By default this will use the GLib default main context unless you have set a custom context using [glib.main_context.MainContext.pushThreadDefault].

All the information is returned in a #GstDiscovererInfo structure.

Methods

GType _getGType()

GType _gType() @property

Discoverer self()Returns `this`, for use in `with` statements.

DiscovererGidBuilder builder()Get builder for [gstpbutils.discoverer.Discoverer] Returns: New builder object

ulong timeout() @propertyGet `timeout` property. Returns: The duration (in nanoseconds) after which the discovery of an individual URI will timeout.

void timeout(ulong propval) @propertySet `timeout` property. Params: propval = The duration (in nanoseconds) after which the discovery of an individual URI will timeout.

bool useCache() @property

void useCache(bool propval) @property

gstpbutils.discoverer_info.DiscovererInfo discoverUri(string uri)Synchronously discovers the given uri.

bool discoverUriAsync(string uri)Appends the given uri to the list of URIs to discoverer. The actual discovery of the uri will only take place if [gstpbutils.discoverer.Discoverer.start] has been called.

void start()Allow asynchronous discovering of URIs to take place. A #GMainLoop must be available for #GstDiscoverer to properly work in asynchronous mode.

void stop()Stop the discovery of any pending URIs and clears the list of pending URIS (if any).
