NAME
       rtplosslog.pl - Log packet loss for a RTP session every minute

SYNOPSIS
       rtplosslog.pl <address> [<port>] [<src_ip>]

DESCRIPTION
       rtplosslog.pl displays the packet loss summary for a specific
       transmitter for each minute that passes.  If no port is specified, then
       port 5004 is assumed.  If no source address is specified, then the
       source address of the first packet recieved is used.

       rtplosslog.pl uses seperate threads for recieving packets and
       displaying statistics, so version 5.8 or greater of perl is recommended
       for stable threading.

       When rtplosslog.pl is started, it waits until the start of a minute
       before starting to log packet loss. Thereafter a row is displayed for
       each minute that passes (even if no packets have been recieved).  The
       log data is sent, with each field seperated by a tab, to STDOUT.
       Additional messages are sent to STDERR.

       The fields in each row are as follows:

       o   The first column is the UNIX timestamp for the start of the
           reported minute.

       o   The second column is the number of packets that were recieved in
           that minute.

       o   The third column is the number of bytes that were recieved in that
           minute (including estimated IP packet headers).

       o   The fourth column is the number of packets that were lost in the
           minute.

       o   The fifth column is the number of packets that arrived late (out of
           order).
