• Insta360 RS One Inch damaged file correction from dual 360 to equirectangular not lining up perfectly [closed]

  25 juillet 2024, par Barry Houldsworth

  I replaced my old Theta Z1 with an Insta360 RS One Inch.

  


  The first time using it for an actual job, 6 of the 50 photos I took came back with damaged files. enter image description here

  


  The Insta360 support team have been completely useless.

  


  I have an image but it's sort of a dual fisheye thing.enter image description here

  


  I found ffmpeg and tried to use that to correct...and it's soooo close but not quite there.

  


  Here is the command I used to process the dual fisheye image to equirectangular

  


  ffmpeg -i input.jpg -vf v360=dfisheye:e:pitch=-180:roll=0:yaw=100:ih_fov=193:iv_fov=193 -qscale:v 1 -frames:v 1 output2.jpg

  


  It works great except there is a very noticeable seam where the two images join. It looks like one of the images needs to be nudged up just a bit before the conversion. But...I don't know how to do that.

  


  Note that this is for photos not video.

  


  Any help would be much appreciated.

  


  Thanks !

  


  I tried the command above and was hoping it would convert from a dual fisheye image to an equirectangular image.

  


  It does work but there is a noticable seam where the two images join.

  


  I have tried tweaking the fov values but that did not seem to help.

  


• Monitoring for failure and quickly restarting systemd service

  16 février 2024, par mzrt

  I am running a 24/7 youtube stream on Ubuntu. My ffmpeg command is wrapped in a systemd service. On several occasions the ffmpeg command has failed and systemd has not restarted quickly enough to keep the youtube stream alive. When this happens I need to daemon-reload and restart the systemd service.

  


  To counter this I have written a bash script that checks the log for stream ending errors, however, it does not seem to be working. I have had failures since implementing this script, and it did not seem to have been triggered.

  


  two questions :

  


  

  1. is there a more efficient way to do what I am doing ?

  


  2. if not, can anyone identify what I am doing wrong ?

  


  


  #!/bin/bash

RESET=0

while true; do
    # Get the current time minus 1 minute
    LAST_1_MINUTE=$(date -d '1 minute ago' '+%b %e %H:%M:%S')
    
    # Run the command to check for the error within the last minute
    if journalctl --since "$LAST_1_MINUTE" | grep -qi "Error writing trailer"; then
        if [ $RESET -lt 1 ]; then
            # Perform actions if error is detected
            sudo systemctl daemon-reload && \
            echo "Restarting master.service by monitor.sh script at $(date)" >> /var/log/monitor.log && \
            sudo systemctl restart master.service
            RESET=2
        fi
    else
        RESET=$((RESET - 1))
    fi

    # Wait for 20 seconds before the next iteration
