 I am encoding a lot of videos at different bitrates and resolutions, I am
 also calculating VMAF score for each encoded videos. While doing this my
 pc randomly crashes/restarts regardless of the specific time, input video
 and the task (video encoding, VMAF calculation). I am using the following
 two commands:
 Video encoding:
 {{{
 ffmpeg -hide_banner -loglevel verbose -nostats -i input.mp4 -crf 20
 -maxrate 0.1M -bufsize 0.2M -s 640x360 -y output.mp4
 }}}
 VMAF calculation"
 {{{
 ffmpeg -hide_banner -loglevel verbose -i output.mp4 -i input.mp4 -lavfi
 "[0]scale=640:360[scaled];[scaled][1]libvmaf" -f null-
 }}}
 When i see output log after pc restart i only see following thing:
