Class Details¶

class GstPbutils.DiscovererInfo(**kwargs)¶

Bases:: GObject.Object
Abstract:: No

Structure containing the information of a URI analyzed by GstPbutils.Discoverer.

classmethod from_variant(variant)¶

Parameters:: variant (GLib.Variant) – A GLib.Variant to deserialize into a GstPbutils.DiscovererInfo.
Returns:: A newly-allocated GstPbutils.DiscovererInfo.
Return type:: GstPbutils.DiscovererInfo

Parses a GLib.Variant as produced by GstPbutils.DiscovererInfo.to_variant() back to a GstPbutils.DiscovererInfo.

New in version 1.6.

copy()¶

Returns:: A copy of the GstPbutils.DiscovererInfo
Return type:: GstPbutils.DiscovererInfo

get_audio_streams()¶

Returns:: A GLib.List of matching GstPbutils.DiscovererStreamInfo. The caller should free it with GstPbutils.DiscovererStreamInfo.list_free().
Return type:: [GstPbutils.DiscovererAudioInfo]

Finds all the GstPbutils.DiscovererAudioInfo contained in self

get_container_streams()¶

Returns:: A GLib.List of matching GstPbutils.DiscovererStreamInfo. The caller should free it with GstPbutils.DiscovererStreamInfo.list_free().
Return type:: [GstPbutils.DiscovererContainerInfo]

Finds all the GstPbutils.DiscovererContainerInfo contained in self

get_duration()¶

Returns:: the duration of the URI in #GstClockTime (nanoseconds).
Return type:: int

get_live()¶

Returns:: whether the URI is live.
Return type:: bool

New in version 1.14.

get_misc()¶

Returns:: Miscellaneous information stored as a Gst.Structure (for example: information about missing plugins). If you wish to use the Gst.Structure after the life-time of self, you will need to copy it.
Return type:: Gst.Structure or None

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

get_missing_elements_installer_details()¶

Returns:: An array of strings containing information about how to install the various missing elements for self to be usable. If you wish to use the strings after the life-time of self, you will need to copy them.
Return type:: [str]

Get the installer details for missing elements

New in version 1.4.

get_result()¶

Returns:: the result of the discovery as a GstPbutils.DiscovererResult.
Return type:: GstPbutils.DiscovererResult

get_seekable()¶

Returns:: the whether the URI is seekable.
Return type:: bool

get_stream_info()¶

Returns:: the structure (or topology) of the URI as a GstPbutils.DiscovererStreamInfo. This structure can be traversed to see the original hierarchy. Unref with gst_discoverer_stream_info_unref() after usage.
Return type:: GstPbutils.DiscovererStreamInfo or None

get_stream_list()¶

Returns:: the list of all streams contained in the #info. Free after usage with GstPbutils.DiscovererStreamInfo.list_free().
Return type:: [GstPbutils.DiscovererStreamInfo]

get_streams(streamtype)¶

Parameters:: streamtype (GObject.GType) – a GObject.GType derived from GstPbutils.DiscovererStreamInfo
Returns:: A GLib.List of matching GstPbutils.DiscovererStreamInfo. The caller should free it with GstPbutils.DiscovererStreamInfo.list_free().
Return type:: [GstPbutils.DiscovererStreamInfo]

Finds the GstPbutils.DiscovererStreamInfo contained in self that match the given streamtype.

get_subtitle_streams()¶

Returns:: A GLib.List of matching GstPbutils.DiscovererStreamInfo. The caller should free it with GstPbutils.DiscovererStreamInfo.list_free().
Return type:: [GstPbutils.DiscovererSubtitleInfo]

Finds all the GstPbutils.DiscovererSubtitleInfo contained in self

get_tags()¶

Returns:: all tags contained in the URI. If you wish to use the tags after the life-time of self, you will need to copy them.
Return type:: Gst.TagList or None

Deprecated since version 1.20: Use gst_discoverer_{container,stream}_info_get_tags() instead.

get_toc()¶

Returns:: TOC contained in the URI. If you wish to use the TOC after the life-time of self, you will need to copy it.
Return type:: Gst.Toc or None

get_uri()¶

Returns:: the URI to which this information corresponds to. Copy it if you wish to use it after the life-time of self.
Return type:: str

get_video_streams()¶

Returns:: A GLib.List of matching GstPbutils.DiscovererStreamInfo. The caller should free it with GstPbutils.DiscovererStreamInfo.list_free().
Return type:: [GstPbutils.DiscovererVideoInfo]

Finds all the GstPbutils.DiscovererVideoInfo contained in self

to_variant(flags)¶

Parameters:: flags (GstPbutils.DiscovererSerializeFlags) – A combination of GstPbutils.DiscovererSerializeFlags to specify what needs to be serialized.
Returns:: A newly-allocated GLib.Variant representing self.
Return type:: GLib.Variant

Serializes self to a GLib.Variant that can be parsed again through GstPbutils.DiscovererInfo.from_variant().

Note that any Gst.Toc (s) that might have been discovered will not be serialized for now.

New in version 1.6.
