Modifying individual PixelFormat settings for Dual streams of a Multispectral Camera

This works perfectly as long as the saving time is shorter than 1/fps. I.e. there are always buffers available.

The intention of FlowSetInfo is to give infos about size and alignment, i.e. memory stuff.
(We developed the Flows with external memory, like a GPU, in mind).
So not the number of “queued” buffers.

If you are using GigE you can access the Nodemap of the Datastream.

I will post a small snippet in the next post …

Or even simpler:
Number of Buffers in Pool = Number of Buffer - Numbers of Buffers you currently hold.

I’m not entirely certain this is compatible with the AcquistionStack::GenTL, but maybe it helps.

void getStreamInfos(const Cvb::Stream& stream)
{
  using S = Cvb::Driver::StreamInfo;

  // basic success
  aquired = getStatisticsInfo(stream, S::NumBuffersAcquired);
  delivered = getStatisticsInfo(stream, S::NumBuffersDelivered);

  // basic error
  lost = getStatisticsInfo(stream, S::NumBuffersLost);
  lostTransfer = getStatisticsInfo(stream, S::NumBuffersLostTransfer);
  lostLocked = getStatisticsInfo(stream, S::NumBuffersLostLocked);

  // usually gev issues
  corruptArrival = getStatisticsInfo(stream, S::NumBuffersCorruptOnArrival);
  corruptDelivery = getStatisticsInfo(stream, S::NumBuffersCorruptOnDelivery);

  // advanced generic info
  locked = getStatisticsInfo(stream, S::NumBuffersLocked);
  pending = getStatisticsInfo(stream, S::NumBuffersPending);
  beingFilled = getStatisticsInfo(stream, S::NumBuffersBeingFilled);
  announced = getStatisticsInfo(stream, S::NumBuffersAnnounced);
  queued = getStatisticsInfo(stream, S::NumBuffersQueued);

  // gev package info
  packages = getStatisticsInfo(stream, S::NumPacketsReceived);
  resendPackages = getStatisticsInfo(stream, S::NumResends);

  // err ... no clue
  triggerLost = getStatisticsInfo(stream, S::NumTriggersLost);
}

inline uint64_t getStatisticsInfo(const Cvb::Stream& stream, Cvb::Driver::StreamInfo info)
{
  try
  {
    return stream.Statistics<uint64_t>(info);
  }
  catch (std::exception e)
  {
    std::cerr << "failed to get info about (as number): " << static_cast<int>(info) << ". Reason: " << e.what() << std::endl;
  }
  catch (...)
  {
    std::cerr << "failed to get info about (as number): " << static_cast<int>(info) << ". Reason: catch(...)" << std::endl;
  }

  return ~uint64_t(0); // i.e. max value is error or not available
}
