Either of these might be problematic. I don't think you can determine at
the RTP protocol level that there is necessarily a problem. RTP
timestamps are not inherently non-decreasing. There *are* datatypes that
have out of order timestamps (only one I am aware of specifically is
MPEG video per RFC 2250) so that this could be totally valid.
