I would be surprised if the current implementation has significant performance overhead. If we discover excessive copies being made, those should be replaced with pass-by-reference.

This is what my old VideoStream app uses: lsl_streaminfo info = lsl_create_streaminfo("VideoStream_0","VideoStream_0",1,requestedFrameRate,cft_int32,""); lsl_xml_ptr desc = lsl_get_desc(info); lsl_xml_ptr chn = lsl_append_child(desc, "channels"); lsl_append_child_value(chn, "name","frame"); lsl_append_child_value(chn,"unit","number"); lsl_xml_ptr sync = lsl_append_child(desc, "synchronization"); lsl_append_child_value(sync,...

Yes, I checked with a fresh download of load_xdf and eeg_load_xdf. Some more information: if you use the options to only load the 'Presentation' marker stream, the function errors out....
