Make HLS Playlist

Use following command to record webcam and encode to MPEG-TS then make playlist:

ffmpeg -f avfoundation -i "0" -hls_list_size 5 -hls_flags append_list -hls_flags omit_endlist -start_number 0 -hls_allow_cache 0 -hls_segment_filename ./segments/live%03d.ts -hls_base_url segments/ live.m3u8

The segments will save tosegmentsfolder.

live.m3u8

#EXTM3U
#EXT-X-VERSION:3
#EXT-X-ALLOW-CACHE:NO
#EXT-X-TARGETDURATION:9
#EXT-X-MEDIA-SEQUENCE:4
#EXTINF:8.333333,
segments/live004.ts
#EXTINF:8.333333,
segments/live005.ts
#EXTINF:8.333333,
segments/live006.ts
#EXTINF:8.333333,
segments/live007.ts
#EXTINF:2.433333,
segments/live008.ts

ffplay -v debug live.m3u8
