--- Comment #2 from Jan Schmidt <thaytan at noraisin.net> ---
I was just looking at this code. I think there's no point just warning and
switching to 'streamable=true' in non fast-start mode or
non-fragmented-streamable mode.

In 'normal' mp4 mode, if you can't seek downstream then you can't rewrite the
mdat to have non-zero size, which means mdat covers the rest of the file,
including any moov header you might write at the end - making it invisible and
therefore the file is unplayable anyway. It would be better to error out, and
fix the unit test accordingly, so I think I'll do that.
