Comment (by rafamiga):

 I've found one cause for can_split being false.
 {{{
     if (hls->has_video) {
         can_split = st->codecpar->codec_type == AVMEDIA_TYPE_VIDEO &&
                     ((pkt->flags & AV_PKT_FLAG_KEY) || (hls->flags &
 HLS_SPLIT_BY_TIME));
         is_ref_pkt = st->codecpar->codec_type == AVMEDIA_TYPE_VIDEO;
     }
 }}}

 The variable is positive when a keyframe happens or split is forced and
 it's a video stream. But just after this this check happens:

 {{{
     if (pkt->pts == AV_NOPTS_VALUE)
         is_ref_pkt = can_split = 0;
 }}}

 Maybe my setup is somewhat brokend and AV_NOPTS happens? As you can see, I
 use Decklink for input.
