Comment (by kelexel):

 I see, in essence m3u8(-specs) and HLS are mutually exclusive.

 Why not keep the current m3u8 -segment_list_type you already created, and
 add another -segment_list_type m3u8_hls or just "hls" ?

 So whatever your planned use for -segment_list_time, you could have goods
 from both worlds ?

 Also, regarding 3., in some cases of HLS you will want -segment_list_size
 0, why ? because HLS allows seek, so in case we are using
 -segment_list_size 0, no segments will be removed from the list, just
 incremented, allowing an HLS-friendly client to seek anywhere in the
 timeline up-to "now".. So it might still be useful to keep this option in
 HLS case .. (although you are correct, if the -segment_list_size is 0, we
 only need once EXT-X-MEDIA-SEQUENCE 1, since we don't regenerate the
 playlist) ..

 Best regards.
