Comment (by DusanBrejka):

 That's what I did but this patch didn't solve the problem.
 Could you please build ffmpeg with more complex setup instead?

 -hls_init_time 1 -start_number 540   -hls_segment_filename "hls/%03d.ts"
 -t 2160 "hls/master.m3u8"

 I tried this again on newly deployed fresh AWS EC2 instance with the very
 same outcome.
