[FFmpeg-user] why hls_list_size can't function correctly

[qw]

Hi,

Hyper fast Audio and Video encoder
usage: ffmpeg [options] [[infile options] -i infile]... {[outfile options] outfile}...

The hls option of '-hls_list_size' can affect output segment number.  Below is the option's description
 
  -hls_list_size     <int>        E....... set maximum number of playlist entries (from 0 to INT_MAX) (default 5)

I use two different value for '-hls_list_size' using the following commands, but the two commands have the same segment number. Why?
 
ffmpeg -y -i test.m3u8.mp4 -threads 0 -vbsf h264_mp4toannexb -strict -3 -c:v copy -c:a copy -f hls -hls_list_size 100 test.m3u8
ffmpeg -y -i test.m3u8.mp4 -threads 0 -vbsf h264_mp4toannexb -strict -3 -c:v copy -c:a copy -f hls -hls_list_size 1000 test.m3u8
