Otherwise picmemset can get called with negative y, resulting in an
invalid write.

Seeking in certain broken files would cause ogg_read_timestamp
to fail because ogg_packet would go into a state where all packets
of stream 1 would be discarded until the end of the stream.

The time scale is set in mdhd, and later validated in the
enclosing trak atom once all of its children have been parsed.
A loose mdhd atom outside of a trak atom could update the time
scale of the last stream without any validation.

This was handled properly in the normal return case at the end
of the function, but not in this special case.
Returning a value larger than the input packet size can cause
problems for certain library users.
Returning the actual input buffer size unconditionally, since
it is not guaranteed that frame_size is set to a sensible
value at this point.
