Instance methods
Methods inherited from ArvStream (17)
arv_stream_get_emit_signals
Check if stream will emit its signals.
since: 0.2.0
arv_stream_get_info_double
since: 0.8.11
arv_stream_get_info_double_by_name
since: 0.8.11
arv_stream_get_info_name
since: 0.8.11
arv_stream_get_info_type
since: 0.8.11
arv_stream_get_info_uint64
since: 0.8.11
arv_stream_get_info_uint64_by_name
since: 0.8.11
arv_stream_get_n_buffers
An accessor to the stream buffer queue lengths.
since: 0.2.0
arv_stream_get_n_infos
since: 0.8.11
arv_stream_get_statistics
An accessor to the stream statistics.
since: 0.2.0
arv_stream_pop_buffer
Pops a buffer from the output queue of stream. The retrieved buffer
may contain an invalid image. Caller should check the buffer status before using it.
This function blocks until a buffer is available.
since: 0.2.0
arv_stream_push_buffer
Pushes a ArvBuffer to the stream thread. The stream takes ownership of buffer,
and will free all the buffers still in its queues when destroyed.
since: 0.2.0
arv_stream_set_emit_signals
Make stream emit signals. This option is
by default disabled because signal emission is expensive and unneeded when
the application prefers to operate in pull mode.
since: 0.2.0
arv_stream_start_thread
Start the stream receiving thread. The thread is automatically started when
the ArvStream object is instantiated, so this function is only useful if
the thread was stopped using arv_stream_stop_thread.
since: 0.6.2
arv_stream_stop_thread
Stop the stream receiving thread, and optionally delete all the ArvBuffer
stored in the stream object queues. Main use of this function is to be able
to quickly change an acquisition parameter that changes the payload size,
without deleting/recreating the stream object.
since: 0.6.2
arv_stream_timeout_pop_buffer
Pops a buffer from the output queue of stream, waiting no more than timeout. The retrieved buffer
may contain an invalid image. Caller should check the buffer status before using it.
since: 0.2.0
arv_stream_try_pop_buffer
Pops a buffer from the output queue of stream. The retrieved buffer
may contain an invalid image. Caller should check the buffer status before using it.
This is the non blocking version of pop_buffer.
since: 0.2.0

g_initable_init
Initializes the object implementing the interface.
Properties
Aravis.GvStream:frame-retention
Amount of time Aravis is wating for frame completion after the last packet is received. A greater value will also increase the maximum frame latency in case of missing packets.
Aravis.GvStream:initial-packet-timeout
Delay before asking for a packet resend after the packet was detected missing for the first time. The reason for this delay is, depending on the network topology, stream packets are not always received in increasing id order. As the missing packet detection happens at each received packet, by verifying if each previous packet has been received, we could emit useless packet resend requests if they are not ordered.
since: 0.8.15
Aravis.GvStream:packet-request-ratio
Maximum number of packet resend requests for a given frame, as a percentage of the number of packets per frame.
Aravis.GvStream:packet-resend
Packet resend policy. This only applies if the device supports packet resend.
Aravis.GvStream:packet-timeout
Timeout while waiting for a packet after a resend request, before asking again.
Aravis.GvStream:socket-buffer-size
Size in bytes of the incoming socket buffer. A greater value helps to lower the number of missing packets, as the expense of an increased memory usage. If the value is not strictly positive, this setting is ignored.

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.
