GstDiscoverer

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 gst_discoverer_discover_uri 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 gst_discoverer_discover_uri_async) and then asks for the discovery to begin (through gst_discoverer_start). By default this will use the GLib default main context unless you have set a custom context using g_main_context_push_thread_default.

All the information is returned in a GstDiscovererInfo structure.

Constructors

gst_discoverer_new

GstDiscoverer *
gst_discoverer_new (GstClockTime timeout,
                    GError ** error)

Creates a new GstDiscoverer with the provided timeout.

Parameters:

timeout

timeout per file, in nanoseconds. Allowed are values between one second (#GST_SECOND) and one hour (3600 * GST_SECOND)

error
No description available
Returns ( [transfer: full] ) –

The new GstDiscoverer. If an error occurred when creating the discoverer, err will be set accordingly and NULL will be returned. If err is set, the caller must free it when no longer needed using g_error_free.

Base structure for information concerning a media stream. Depending on the stream type, one can find more media-specific information in GstDiscovererAudioInfo, GstDiscovererVideoInfo, and GstDiscovererContainerInfo.

The GstDiscovererStreamInfo represents the topology of the stream. Siblings can be iterated over with gst_discoverer_stream_info_get_next and gst_discoverer_stream_info_get_previous. Children (sub-streams) of a stream can be accessed using the GstDiscovererContainerInfo API.

As a simple example, if you run GstDiscoverer on an AVI file with one audio and one video stream, you will get a GstDiscovererContainerInfo corresponding to the AVI container, which in turn will have a GstDiscovererAudioInfo sub-stream and a GstDiscovererVideoInfo sub-stream for the audio and video streams respectively.
