t_blob_observation Struct Reference

Collaboration diagram for t_blob_observation:

Data Fields
struct t_blobwatch *	source
uint64_t	id
	Internal ID for this observation, may be set by the blobwatch implementation if it needs to know this.
uint64_t	sequence_id
	The sequence ID of this mosaic, must be stable across all frames of a mosaic. Monotonically increases.
int64_t	timestamp_ns
struct t_blob *	blobs
uint32_t	num_blobs
struct xrt_frame *	frame
	Optional reference to the frame the blobs were extracted from, may be NULL.

Field Documentation

frame

struct xrt_frame* t_blob_observation::frame

Optional reference to the frame the blobs were extracted from, may be NULL.

The reference is owned by the observation: the blob sink receiving it takes ownership and must release it with xrt_frame_reference (or pass it on to another sink that does).

id

uint64_t t_blob_observation::id

Internal ID for this observation, may be set by the blobwatch implementation if it needs to know this.

Referenced by ipcproto.common.Call::__init__().

sequence_id

uint64_t t_blob_observation::sequence_id

The sequence ID of this mosaic, must be stable across all frames of a mosaic. Monotonically increases.
