Comment (by barhom):

 Replying to [comment:1 j_karthic]:
 > As per the HLS specification, bandwidth attribute is mandatory. So it
 would be in violation of the spec to create a master playlist without
 bandwidth information.

 If so, should we not even copy the input to the output vs_0/playlist.m3u8?
 Otherwise we are creating a working playlist.m3u8 but a non-working

 MPEG2 video inside HLS containers are also invalid according to the spec
 but they are still allowed.
