You can ignore those messages, they are normal and expected. They just say that some of the outputs (functionals in CSV and HTK format and all LLDs) are disabled because you did not specify output paths for them on the command-line.

Thanks for your reply. So do those outputs affect the output features of .wav file ?

No, they do not affect the features. There are just different formats that the features can be output in (ARFF, CSV, HTK). You are using -O which outputs in the ARFF format. If you specify -csvoutput <path>, you'll get the features in CSV format, for example. See https://github.com/audeering/opensmile/blob/master/config/shared/standard_data_output.conf.inc.
