Not quite.
The code was looking for a *second* start code in order to determine length of
data.
When using the unchecked version, which does not do that, the length is assumed
to be the full length of passed data, minus the offset at which the start code
is found.
In reverse mode, it seems we get a huge amount of data from the parser, so the
NALU length is set to a very large amount of data, as it does not attempt to
locate the start of the next data bit.
