OK. so I downloaded the quicktime file format specification document from apple
and it came to me like a vision, like a flash written across the sky...or at
least on one of the pages in the PDF document:
quicktime is a network order wrapper format. It likes things in big endian
format.
and that's always the question with wrappers: do they expect the data in them
to follow their byte ordering? has lead to much pulling of out of my hair on
other projects as well, dealing with obscure networking protocols.
Of course I haven't tried your suggestion yet so I'll refrain from making any
heretical blasphemous utterances until I confirm what you wrote.
