One of the pain points I experienced was that ffmpeg makes CPU in high temperature, so server die. In that case, you may want to check CPU temperature, and watch sensors enables to see it in realtime.
To watch sensors, you need to install lm-sensors
sudo yum install -y lm_sensors
To detect sensors, you need to run:
sudo sensors-detect --auto
To check your sensors' status
sensors
To check sensors' status with auto update
watch sensors
