 Summary of the ticket:

 add support to EXT-X-STREAM-INF and BANDWIDTH field in the generated M3U8
 output.

 Here is spec from http://tools.ietf.org/html/draft-pantos-http-live-
 streaming-07

 BANDWIDTH

    The value is a decimal-integer of bits per second.  It MUST be an
    upper bound of the overall bitrate of each media segment (calculated
    to include container overhead) that appears or will appear in the
    Playlist.

    Every EXT-X-STREAM-INF tag MUST include the BANDWIDTH attribute

 Here is command line:

 C:\ffmpeg\ffmpeg.exe -re -i "rtmp://bar/foo.flv" -y -c:v copy -c:a copy
 -hls_time 6 -hls_list_size 5 -hls_wrap 30 -start_number 1
 "C:\Tools\Foo\stream.m3u8"
