Segmentation allows interleave and packing of packets with framing data
and other tracks at very low bitrate overhead regardless of packet size.

Typical overheads of the Ogg container are around 1%, versus ~5% for
other popular container formats.

This is a consequence of the unary encoding of segment lengths in the
page headers, used to acheive the low overhead with bounded read-ahead.
