----------------------------------+----------------------------------
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:
