From: Vishwanath Dixit <vdi...@akamai.com>
Progress report computation functionality was assuming the first
PTS value to be zero, but, when 'copyts' is enalbed, the first PTS
can be any big number. This was eventually causing display of
weird statistics during execution of an ffmpeg command. To overcome
this issue, the actual first PTS value has to be considered.
