Issue Details


How can I detect when a frame has been dropped from my FireWire camera during acquisition?

Solution

Use the IMAQdx property node, LostBufferCount, to return a running count of the number of dropped frames from an IMAQdx session.

Related properties are the RequestedResendPacketsReceivedResendPackets and LostPacketCount.

  • RequestedResendPackets is the number of packets that were requested to be resent during an acquisition session.

  • ReceivedResendPackets is the number of packets that were requested to be resent during an acquisition session and that were completed.

  • LostPacketCount is the number of lost packets during an acquisition.
