ffmpeg split segment use hlsenc by keyframe, if you want to split segment
*ASAP*,
you can try set your streaming *GOP(Group Of Picture)* shorter,
for example: gop_size = 60, c->time_base = (AVRational){1,60};
in command line : -r:v 60 -g 60
if can accept split segment at non-keyframe, you can use hls_time and
hls_flags split_by_time.
