GstPbutils.Discoverer.prototype.new

function GstPbutils.Discoverer.prototype.new(timeout: Number): {
    // javascript wrapper for 'gst_discoverer_new'
}

Creates a new GstPbutils.Discoverer with the provided timeout.

GstPbutils.Discoverer.prototype.discover_uri

function GstPbutils.Discoverer.prototype.discover_uri(uri: String): {
    // javascript wrapper for 'gst_discoverer_discover_uri'
}

Synchronously discovers the given uri.

A copy of uri will be made internally, so the caller can safely GLib.prototype.free afterwards.

GstPbutils.Discoverer.prototype.discover_uri_async

function GstPbutils.Discoverer.prototype.discover_uri_async(uri: String): {
    // javascript wrapper for 'gst_discoverer_discover_uri_async'
}

Appends the given uri to the list of URIs to discoverer. The actual discovery of the uri will only take place if GstPbutils.Discoverer.prototype.start has been called.

A copy of uri will be made internally, so the caller can safely GLib.prototype.free afterwards.

GstPbutils.Discoverer.prototype.start

function GstPbutils.Discoverer.prototype.start(): {
    // javascript wrapper for 'gst_discoverer_start'
}

Allow asynchronous discovering of URIs to take place. A GMainLoop (not introspectable) must be available for GstPbutils.Discoverer to properly work in asynchronous mode.

GstPbutils.Discoverer.prototype.stop

function GstPbutils.Discoverer.prototype.stop(): {
    // javascript wrapper for 'gst_discoverer_stop'
}

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

discovered

function discovered_callback(self: GstPbutils.Discoverer, info: GstPbutils.DiscovererInfo, error: GError (not introspectable), user_data: Object): {
    // javascript callback for the 'discovered' signal
}

Will be emitted in async mode when all information on a URI could be discovered, or an error occurred.

When an error occurs, info might still contain some partial information, depending on the circumstances of the error.

Flags: Run Last

finished

function finished_callback(self: GstPbutils.Discoverer, user_data: Object): {
    // javascript callback for the 'finished' signal
}

Will be emitted in async mode when all pending URIs have been processed.

Flags: Run Last

load-serialized-info

function load_serialized_info_callback(self: GstPbutils.Discoverer, uri: String, user_data: Object): {
    // javascript callback for the 'load-serialized-info' signal
}

Retrieves information about a URI from and external source of information, like a cache file. This is used by the discoverer to speed up the discovery.

Flags: Run Last

Since : 1.24

source-setup

function source_setup_callback(self: GstPbutils.Discoverer, source: Gst.Element, user_data: Object): {
    // javascript callback for the 'source-setup' signal
}

This signal is emitted after the source element has been created for, so the URI being discovered, so it can be configured by setting additional properties (e.g. set a proxy server for an http source, or set the device and read speed for an audio cd source).

This signal is usually emitted from the context of a GStreamer streaming thread.

Flags: Run Last

starting

function starting_callback(self: GstPbutils.Discoverer, user_data: Object): {
    // javascript callback for the 'starting' signal
}

Will be emitted when the discover starts analyzing the pending URIs

Flags: Run Last

timeout

“timeout” Number

The duration (in nanoseconds) after which the discovery of an individual URI will timeout.

If the discovery of a URI times out, the GstPbutils.DiscovererResult.TIMEOUT will be set on the result flags.

Flags : Read / Write / Construct

use-cache

“use-cache” Number

Flags : Read / Write / Construct

vfunc_discovered
