property Streamname
as %String(MAXLEN=1000) [ InitialExpression = "%f" ];
Name to transmit as the name of the stream content. May include timestamp specifiers. The %f specifier if present will be
replaced with the name of the stream's original source filename (stripped of characters illegal in target filenames).
See the method Ens.Util.File.CreateTimestamp() for documentation of timestamping options.
If empty, the stream content will be sent as a single counted block without any associated stream name.
