Segment files removed from the playlist are deleted after a period of time
equal to the duration of the segment plus the duration of the playlist.
+@item hls_flags split_by_time
+If this flags is set, allow segments to start on frames other than keyframes.
+Thisimproves behavior on some players when the time between keyframes is
+inconsistent, but may make things worse on others, and can cause some oddities
+during seeking. This flag should be used with hls_time option.

@item hls_playlist_type event
Emit @code{#EXT-X-PLAYLIST-TYPE:EVENT} in the m3u8 header. Forces
@option{hls_list_size} to 0; the playlist can only be appended to.
