<!-- struct Discoverer -->
The `Discoverer` 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 `DiscovererExt::discover_uri`
with the URI one wishes to discover.
The non-blocking mode requires a running `glib::MainLoop` iterating a
`glib::MainContext`, where one connects to the various signals, appends the
URIs to be processed (through `DiscovererExt::discover_uri_async`) and then
asks for the discovery to begin (through `DiscovererExt::start`).
By default this will use the GLib default main context unless you have
set a custom context using `glib::MainContext::push_thread_default`.
All the information is returned in a `DiscovererInfo` structure.
# Implements
[`DiscovererExt`](trait.DiscovererExt.html), [`glib::object::ObjectExt`](../glib/object/trait.ObjectExt.html)
<!-- trait DiscovererExt -->
Trait containing all `Discoverer` methods.
# Implementors
[`Discoverer`](struct.Discoverer.html)
<!-- impl Discoverer::fn new -->
Creates a new `Discoverer` with the provided timeout.
## `timeout`
timeout per file, in nanoseconds. Allowed are values between
one second (`GST_SECOND`) and one hour (3600 * `GST_SECOND`)
# Returns
The new `Discoverer`.
If an error occurred when creating the discoverer, `err` will be set
accordingly and `None` will be returned. If `err` is set, the caller must
free it when no longer needed using `glib::Error::free`.
<!-- trait DiscovererExt::fn discover_uri -->
Synchronously discovers the given `uri`.
A copy of `uri` will be made internally, so the caller can safely `g_free`
afterwards.
## `uri`
The URI to run on.
# Returns
the result of the scanning. Can be `None` if an
error occurred.
<!-- trait DiscovererExt::fn 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 `DiscovererExt::start` has
been called.
A copy of `uri` will be made internally, so the caller can safely `g_free`
afterwards.
## `uri`
the URI to add.
# Returns
`true` if the `uri` was successfully appended to the list of pending
uris, else `false`
<!-- trait DiscovererExt::fn start -->
Allow asynchronous discovering of URIs to take place.
A `glib::MainLoop` must be available for `Discoverer` to properly work in
asynchronous mode.
<!-- trait DiscovererExt::fn stop -->
Stop the discovery of any pending URIs and clears the list of
pending URIS (if any).
<!-- trait DiscovererExt::fn connect_discovered -->
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.
## `info`
the results `DiscovererInfo`
## `error`
`glib::Error`, which will be non-NULL if an error
occurred during discovery. You must not
free this `glib::Error`, it will be freed by
the discoverer.
<!-- trait DiscovererExt::fn connect_finished -->
Will be emitted in async mode when all pending URIs have been processed.
<!-- trait DiscovererExt::fn connect_source_setup -->
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.
## `source`
source element
<!-- trait DiscovererExt::fn connect_starting -->
Will be emitted when the discover starts analyzing the pending URIs
<!-- trait DiscovererExt::fn get_property_timeout -->
The duration (in nanoseconds) after which the discovery of an individual
URI will timeout.
If the discovery of a URI times out, the `DiscovererResult::Timeout` will be
set on the result flags.
<!-- trait DiscovererExt::fn set_property_timeout -->
The duration (in nanoseconds) after which the discovery of an individual
URI will timeout.
If the discovery of a URI times out, the `DiscovererResult::Timeout` will be
set on the result flags.

<!-- struct DiscovererStreamInfo -->
Base structure for information concerning a media stream. Depending on the
stream type, one can find more media-specific information in
`DiscovererAudioInfo`, `DiscovererVideoInfo`, and
`DiscovererContainerInfo`.
The `DiscovererStreamInfo` represents the topology of the stream. Siblings
can be iterated over with `DiscovererStreamInfoExt::get_next` and
`DiscovererStreamInfoExt::get_previous`. Children (sub-streams) of a
stream can be accessed using the `DiscovererContainerInfo` API.
As a simple example, if you run `Discoverer` on an AVI file with one audio
and one video stream, you will get a `DiscovererContainerInfo`
corresponding to the AVI container, which in turn will have a
`DiscovererAudioInfo` sub-stream and a `DiscovererVideoInfo` sub-stream
for the audio and video streams respectively.
