[FFmpeg-user] ffmpeg first_PTS value range and min_comp, min_hard_comp

[Amar Mash]

Hello All, looking for some help pls.

i have live video and audio that is out of sync.

to get it in sync i have so far for this filter complex.

-filter_complex "
aresample=async=1000:min_hard_comp=0.100000:first_pts=0,adelay=delays=562|562
" \

A few questions:
1. Currently I have first_pts=0this i understand is the default and is not
making any changes. What is the value range i can use for this filter?

2. currently i have min_hard_comp=0.100000. this i understand is default
and is not making any changes. what is the numerical value range i can use
here?

thank you.
