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() static nothrow

GType _gType() @property nothrow

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

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

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

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

bool useCache() @property nothrow

void useCache(bool propval) @property nothrow

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

bool discoverUriAsync(string uri) nothrowAppends 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() nothrowAllow asynchronous discovering of URIs to take place. A #GMainLoop must be available for #GstDiscoverer to properly work in asynchronous mode.

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