FLV documentation stipulates that timestamp must start at zero.
In order to respect this rule, keep the first timestamp around
and offset the timestamp from this value. This allow for longer
recording time in presence of timestamp that does not start
at 0 already.

Some Flash players (for instance JW Player) always expect a duration
tag, otherwise they don't start playback.
If duration can be queried from the sink pads or is provided as a tag,
use it. Otherwise try to determine it from the last seen timestamp of
the sink pads after EOS and rewrite it in the header before writing
the index.
