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_get_analytics_relation_meta(buffer)

Parameters:

Return type:

GstAnalytics.RelationMeta or None

Retrives the meta or None if it doesn’t exist

New in version 1.24.
