    87 FFmpeg supports splitting files (using "-f segment" for the output, see [http://ffmpeg.org/ffmpeg.html#segment_002c-stream_005fsegment_002c-ssegment segment muxer]) into time based chunks, useful for [http://en.wikipedia.org/wiki/HTTP_Live_Streaming HTTP live streaming] style file output.

     127
     128FFmpeg doesn't (today) support varying a bitrate based on changing network conditions.  It does support outputting in "different" bitrates, at the same time, however [http://stackoverflow.com/questions/12041077/ffmpeg-output-to-multiple-files-simultaneously see here], which is vaguely related.
