Details¶

class GstAnalytics.TensorMeta¶

New in version 1.26.

get(index)¶

Parameters:: index (int) – The number of the tensor to get
Returns:: a GstAnalytics.Tensor
Return type:: GstAnalytics.Tensor

Retrieves a tensor from the GstAnalytics.TensorMeta, the index must be smaller than GstAnalytics.TensorMeta.num_tensors

New in version 1.26.

get_by_id(id)¶

Parameters:: id (int) – A #GQuark identifying tensor-encoding
Returns:: a GstAnalytics.Tensor with id matching id. Otherwise None will be returned.
Return type:: GstAnalytics.Tensor or None

Get the first tensor from the GstAnalytics.TensorMeta identified by id.

New in version 1.28.

get_index_from_id(id)¶

Parameters:: id (int) – The tensor id to look for
Returns:: The index of the tensor inthe meta, or -1 if its not found.
Return type:: int

Finds the first tensor with the requsted ID in the meta

New in version 1.26.

get_typed_tensor(tensor_id, data_type, order, dims)¶

Parameters:

tensor_id (int) – A #GQuark identifying the tensor-encoding
data_type (GstAnalytics.TensorDataType) – The data type of the tensor
order (GstAnalytics.TensorDimOrder) – The order of the tensor to read from the memory
dims ([int] or None) – An optional array of dimensions, where GObject.G_MAXSIZE means ANY.

Returns:

a matching GstAnalytics.Tensor, otherwise None

Return type:

GstAnalytics.Tensor or None

Get the first tensor from the GstAnalytics.TensorMeta identified by tensor_id, matching the reading order, dimensions and the data type and optionally the dimensions. Validate whether the Gst.Buffer has enough size to hold the tensor data.

New in version 1.28.

set(tensors)¶

Parameters:: tensors ([GstAnalytics.Tensor]) – An array of poiners to GstAnalytics.Tensor

Sets tensors into the GstAnalytics.TensorMeta

New in version 1.26.
