Note: This error can occur if the Ethernet adapter, camera network connection, and camera GigE streaming parameters (PacketSize and PacketDelay) are not configured for optimum operation.

imaqmex('feature', '-gigeDisablePacketResend', true);

Note: 'gigeDisablePacketResend' option will be reset by the imaqreset command.

When dropped frames are allowed, it is relevant to know how many frames and which frames have been dropped during acquisition. The BlockID field in the metadata returned by getdata corresponds to the frame number set by the camera. A simple way to visualize this is to plot the acquired frames' BlockID and BlockID differences, as in the following code snippet:

[img, ts, metadata] = getdata(vid, vid.FramesAvailable);

blockIDs = [metadata.BlockID];

figure;
plot(blockIDs, '.')

figure;
plot(diff(blockIDs), '-x')
