Comment (by saste):

 Replying to [comment:15 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.

 Added an option -segment_list_live which should address the issue.

 Would you mind to comment on ffmpeg-devel:

 I'll attach the patches to test, which I posted to ffmpeg-devel, for your
