    qtdemux: guess bitrate if only one stream's bitrate is unknown

    If the bitrates for all but one audio/video streams are known, and the
    total stream size and duration can be determined, this calculates the
    unkown bitrate as (stream size / duration) - (sum of known bitrates).
    While this is not guaranteed to be very accurate, it should be good
    enough for most purposes.

    For example, this is useful for H.263 + AAC streams where no 'btrt' atom
    is available for the video portion.
