Details¶

GstAnalytics.buffer_add_analytics_relation_meta(buffer)¶

Parameters:: buffer (Gst.Buffer) – a Gst.Buffer
Returns:: Newly attached GstAnalytics.RelationMeta
Return type:: GstAnalytics.RelationMeta or None

Attach a analysis-results-meta-relation meta (GstAnalytics.RelationMeta)to buffer.

A GstAnalytics.RelationMeta is a metadata describing relation between other analysis meta. It’s more efficient to use GstAnalytics.buffer_add_analytics_relation_meta_full and providing the maximum number of analysis meta that will attached to a buffer.

New in version 1.24.

GstAnalytics.buffer_add_analytics_relation_meta_full(buffer, init_params)¶

Parameters:

buffer (Gst.Buffer) – a Gst.Buffer
init_params (GstAnalytics.RelationMetaInitParams) – Initialization parameters

Returns:

Newly attached GstAnalytics.RelationMeta

Return type:

GstAnalytics.RelationMeta or None

Attache a analysis-results relation-meta (GstAnalytics.RelationMeta) to buffer.

A GstAnalytics.RelationMeta is a metadata describing relation between other analysis meta.

New in version 1.24.

GstAnalytics.buffer_add_tensor_meta(buffer)¶

Parameters:: buffer (Gst.Buffer) – A writable Gst.Buffer
Returns:: The new GstAnalytics.TensorMeta
Return type:: GstAnalytics.TensorMeta

Adds a GstAnalytics.TensorMeta to a buffer or returns the existing one

New in version 1.26.

GstAnalytics.buffer_get_analytics_relation_meta(buffer)¶

Parameters:: buffer (Gst.Buffer) – a Gst.Buffer
Returns:: The GstAnalytics.RelationMeta if there is one
Return type:: GstAnalytics.RelationMeta or None

Retrives the meta or None if it doesn’t exist

New in version 1.24.

GstAnalytics.buffer_get_tensor_meta(buffer)¶

Parameters:: buffer (Gst.Buffer) – A Gst.Buffer
Returns:: The GstAnalytics.TensorMeta if there is wone
Return type:: GstAnalytics.TensorMeta or None

Gets the GstAnalytics.TensorMeta from a buffer

New in version 1.26.

GstAnalytics.cls_mtd_get_mtd_type()¶

GstAnalytics.od_mtd_get_mtd_type()¶

Returns:: Opaque id of the GstAnalytics.Mtd type
Return type:: int

Get an id that represent object-detection metadata type

New in version 1.24.

GstAnalytics.relation_get_length(instance)¶

Parameters:: instance (GstAnalytics.RelationMeta) – Instance of GstAnalytics.RelationMeta
Returns:: Number of analysis-meta attached to this instance.
Return type:: int

Get number of relatable meta attached to instance

New in version 1.24.

GstAnalytics.relation_meta_api_get_type()¶

Returns:: GObject.GType of GstAnalytics.RelationMeta
Return type:: GObject.GType

New in version 1.24.

GstAnalytics.segmentation_mtd_get_mtd_type()¶

Returns:: A #GstAnalyticsMtdType type
Return type:: int
