#6630: Using stream segmenter produces .ts file with non-zero start time

I am trying to adjust the timestamps of a collection of mpegts files. The
timestamps of these files seem to be all offset by some arbitrary number
1.466667s - 1.485333s.
The HLS stream that I am generating contains 3 separate qualities. A
1280x720, and 852x480 version. Each of the segments for these qualities
come in individually with identical timestamps. I rewrite the timestamps
by running them through the stream segmenter and specifying
`-initial_offset`. I do this because the timestamps are not always
continuous between segments as I receive them.
