1024 bytes may not be enough data to find the first timestamp. Data
pages are usually around 4k.

It looks like this is starting in the middle of the header data. Try
starting the buffer with the first OggS, the second one before this
section. It looks corrupt in other ways, with incomplete tag values
and without 4 bytes between tag entries, but that may be an effect of
the way you've dumped it.
