Possible to provide to DLNA an rtsp stream?

Hi, thanks for itm it works fine. I hoped it can accept ffpeg as input.. where I can set as input an RTSP stream, it looks not possible :(
Unfortunately Serviio is not able to "copy" directly the stream to DLNA, resulting on high bitrate the output and CPU consumption, even if transcoding is disabled. I hope to find something... after all my request is very simple..
