    148148FFmpeg doesn't (today) support varying the encoding bitrate based on fluctuating network conditions.  It does support outputting in several "different" fixed bitrates, at the same time, however [http://stackoverflow.com/questions/12041077/ffmpeg-output-to-multiple-files-simultaneously see here], which is somewhat related.  Also if you are during direct capture from directshow, the input device starts dropping frames when there is congestion, which somewhat simulates a varying bitrate.
