[FFmpeg-user] HTML5 live streaming

[Vlad Kroutik]

You do not need m3u8-segmenter as ffmpeg support segmented output and its
built it. Look at the ffmpeg docs or example:
/usr/local/bin/ffmpeg -i hi.ts -loglevel debug
-analyzeduration 6M  -map 0 -c copy -f segment -segment_time 10
-segment_list hi.m3u8 hi_%05d.ts
