Class
AravisChunkParser
Description [src]
final class Aravis.ChunkParser : GObject.Object
{
/* No available fields */
}ArvChunkParser provides a class for the instantiation of chunk parsers used for the extraction of chunk data
stored in the stream payload.
Chunks are tagged blocks of data stored in a ArvBuffer containing a ARV_BUFFER_PAYLOAD_TYPE_CHUNK_DATA
payload. The tags allow a chunk parser to dissect the data payload into its elements and to identify the content.
Chunk data are enabled using either arv_camera_set_chunks() or arv_camera_set_chunk_mode(). Both
functions are simple convenience wrappers that handle the setting of ChunkModeActive, ChunkSelector and ChunkEnable
GENICAM features.
Here is an example of this API in use: tests/arvchunkparsertest.c.
Instance methods
arv_chunk_parser_set_integer_feature_value
Set a feature value using a 64 bit value. The main use for this function is to set a Selector feature, in order to access the corresponding chunk value. As the Genicam data owned by the parser is not shared with the device, this function is limited to features that don’t trigger device access.
since: 0.8.35
arv_chunk_parser_set_string_feature_value
Set a feature value using a string. The main use for this function is to set a Selector feature, in order to access the corresponding chunk value. As the Genicam data owned by the parser is not shared with the device, this function is limited to features that don’t trigger device access.

Signals
Signals inherited from GObject (1)
GObject::notify
The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.
