SECTION:element-tensor_sparse_dec

tensor_sparse_dec is a GStreamer element to decode incoming sparse tensor into static (dense) format.

The input is always in the format of other/tensors,format=sparse. The output is always in the format of ohter/tensors,format=static.

Please see also tensor_sparse_enc.
