f89caeff5c 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.

6e2774af55 qtdemux: Export max bitrate for AMR-NB/-WB streams
This parses the 'damr' atom if present, and exports the maximum bitrate
of the stream using the mode set field to determine the highest bitrate
frame type that might be present.

You would end up on some architectures with 0 being written out
instead of the proper value.
