Class Details

class GstPbutils.DiscovererStreamInfo(**kwargs)

Bases:

GObject.Object

Abstract:

No

Base structure for information concerning a media stream. Depending on the stream type, one can find more media-specific information in GstPbutils.DiscovererAudioInfo, GstPbutils.DiscovererVideoInfo, and GstPbutils.DiscovererContainerInfo.

The GstPbutils.DiscovererStreamInfo represents the topology of the stream. Siblings can be iterated over with GstPbutils.DiscovererStreamInfo.get_next() and GstPbutils.DiscovererStreamInfo.get_previous(). Children (sub-streams) of a stream can be accessed using the GstPbutils.DiscovererContainerInfo API.

As a simple example, if you run GstPbutils.Discoverer on an AVI file with one audio and one video stream, you will get a GstPbutils.DiscovererContainerInfo corresponding to the AVI container, which in turn will have a GstPbutils.DiscovererAudioInfo sub-stream and a GstPbutils.DiscovererVideoInfo sub-stream for the audio and video streams respectively.

classmethod list_free(infos)

Parameters:

infos ([GstPbutils.DiscovererStreamInfo]) – a GLib.List of GstPbutils.DiscovererStreamInfo

Decrements the reference count of all contained GstPbutils.DiscovererStreamInfo and fress the GLib.List.

get_caps()

Returns:

the Gst.Caps of the stream. Unref with #gst_caps_unref after usage.

Return type:

Gst.Caps or None

get_misc()

Returns:

additional information regarding the stream (for example codec version, profile, etc..). If you wish to use the Gst.Structure after the life-time of self you will need to copy it.

Gst.Structure or None

Deprecated since version ???: This functions is deprecated since version 1.4, use GstPbutils.DiscovererInfo.get_missing_elements_installer_details

get_next()

Returns:

the next GstPbutils.DiscovererStreamInfo in a chain. None for final streams. Unref with #gst_discoverer_stream_info_unref after usage.

Return type:

GstPbutils.DiscovererStreamInfo or None

get_previous()

Returns:

the previous GstPbutils.DiscovererStreamInfo in a chain. None for starting points. Unref with #gst_discoverer_stream_info_unref after usage.

Return type:

GstPbutils.DiscovererStreamInfo or None
