Various media ingest servers read the incoming stream's advertised bit
rate from this box.

As it is only defined for timed metadata tracks in QTFF, limit it to
just MODE_MP4 (ISOBMFF) for now.

Unifies the MPEG-4 bit rate value calculation, and attempts to utilize
it everywhere matching.

Jan Ekström (5):
  avformat/movenc: split MPEG-4 bit rate value calculation
  avformat/movenc: utilize the maximum bit rate in ISML writing
  avformat/movenc: implement writing of the btrt box
  avformat/movenc: use more fall-back values for average bit rate fields
  avformat/movenc: simplify ISML manifest bit rate setting
