Issue with creating hls m3u8 playlist with .m4s

Description

Summary of the bug:
I’m trying to create hls m3u8 playlist with .m4s files instead of .ts. It needs for streaming h265 video from live RTSP camera. I’m trying to add hls_flags delete_segments+append_list to remove the end of file + add segments to the m3u8 file but look like ffmpeg skips this option. Also m3u8 creates only after stopping ffmpeg command, but should during the process.
How to reproduce:

ffmpeg -use_wallclock_as_timestamps 1 \
      -loglevel warning \
      -fflags nobuffer \
      -rtsp_transport tcp  \
      -i rtsp://username:password@192.168.2.252:554/Streaming/Channels/101 \
      -c:v libx264 -b:v 1500k \
      -c:a aac \
      -b:a 64k \
      -ar 44100 \
      -af aresample=async=1000 \
      -g 48 \
      -keyint_min 48 \
      -sc_threshold 0 \
      -use_localtime 1 \
      -hls_time 2 \
      -hls_list_size 2 \
      -hls_flags delete_segments+append_list \
      -c:v libx264 -b:v 1500k \
      -hls_playlist_type vod \
      -hls_segment_type fmp4 \
      -hls_base_url ‘/api/v3/cameras/5d4442faa34dbe188129ccbe/live?token=[TOKEN]&file=’ \
      -hls_segment_filename 5d4442faa34dbe188129ccbe-%s.ts \
      5d4442faa34dbe188129ccbe.m3u8

Expected behaviour:

  1. It creates 5d4442faa34dbe188129ccbe.m3u8 when starting process
  2. Creates 5d4442faa34dbe188129ccbe.m3u8 without #EXT-X-ENDLIST
  3. Should have only 2 segments filenames

What I have in result:

  1. It creates 5d4442faa34dbe188129ccbe.m3u8 only after force stop process (control + C)
  2. Creates 5d4442faa34dbe188129ccbe.m3u8 with #EXT-X-ENDLIST in the end of file
  3. The file has all m4s segments filenames

Component: ffmpegundetermined

Are you reporting an issue with rtsp input or with hls output?

Please test current FFmpeg git head and post a simplified command line you tested together with the complete, uncut console output to make this a valid ticket.

Resolution: wontfix
Status: newclosed

Yes, because you are using hls_playlist_type argument and "EVENT or VOD playlists imply sliding window (hls_list_size) cannot be used"

reference documentation said: https://ffmpeg.org/ffmpeg-formats.html#Options-6

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

hls_playlist_type vod
Emit #EXT-X-PLAYLIST-TYPE:VOD in the m3u8 header. Forces hls_list_size to 0; the playlist must not change.

you should not use hls_playlist_type, it will ok.
