IFrameQueueSinkListener

IFrameQueueSinkListener is the interface used by the FrameQueueSink to notfiy about state changes and provide a new frame callback.

Example

[C#]
class FrameQueueSinkListener : IFrameQueueSinkListener
{
    public void SinkConnected(FrameQueueSink sink, FrameType frameType)
    {
        // here we allocate and queue 5 buffers which too already have the right type
        sink.AllocAndQueueBuffers(5);
    }
    public void SinkDisconnected(FrameQueueSink sink, IFrameQueueBuffer[] dequeuedInputBuffers)
    {
        foreach(IFrameQueueBuffer buf in dequeuedInputBuffers )
        {
            // this is practically sink.PopInputQueueBuffers
        }
        // these are the already copied buffers for which we were not called for/didn't already pop
        IFrameQueueBuffer[] outputBuffers = sink.PopAllOutputQueueBuffers();
    }
    public void FramesQueued(FrameQueueSink sink)
    {
        IFrameQueueBuffer[] buffers = sink.PopAllOutputQueueBuffers();
        foreach (IFrameQueueBuffer buf in buffers)
        {
            // call your function on buf
            // do_something( buf );
            // this sample expects do_something not to hold onto the buffer
            // because of this, we directly queue it back into the sink input queue
            sink.QueueBuffer(buf);
        }
        // we can exit here, because when new buffers arrived after we called PopAllOutputQueueBuffers, we are immediatly called again
    }
}

[C#]
FrameQueueSinkListener listener = new FrameQueueSinkListener();
FrameQueueSink sink = new FrameQueueSink(listener, MediaSubtypes.RGB32);
ICImagingControl1.Sink = sink;
