/* changing the way the mdat size is computed.
The real purpose of the mdat size is to know the amount to skip to get to the next
atom, which is the moov; the size of media in the mdat is almost secondary. Therefore,
it is of utmost importance that the mdat size "points" to where the moov actually
begins. Now, the moov begins right after the last data we wrote, so how could the sum
of all chunk sizes be different from the total size of what has been written? Well, it
can happen when the writing was unexpectedly stopped (because of lack of disk space,
for instance), in this case a chunk may be partially written (the partial write is not
necessarily erased) but it may not be reflected in the chunk size list (which may
believe it hasn't been written or on the contrary that it has been fully written). In
the case of such a mismatch, there is either unused data in the mdat (not very good,
but tolerable) or when reading the last chunk it will read the beginning of the moov
as part of the chunk (which means the last chunk won't be correctly decoded), both of
which are still better than losing the whole recording. In the long run it'll probably
be attempted to always clean up back to a consistent state, but at any rate it is
always safer to have the mdat size be computed using the position where the moov
actually begins, rather than using the size it is thought the mdat has.
Therefore, I will record where we are just before writing the moov, to serve when
updating the mdat size. */
