• Packet Corruption : Why sometimes ffmpeg .bat batch video editing makes my computer unstable unable to restart ?

  13 juin 2022, par principal-ideal-domain

  I'm doing very time consuming ffmpeg video editing. That's why I put my commands into a .bat batch file and run them over night. Usually that works fine, but from time to time when I look the next moring I see an error message of this kind :

  


  

  


  From that state on, I didn't find any good way to close the console. When I press the [x] button in the top right corner, it freezes. When I try to kill the application using the task manager nothing happens. Even explorer.exe cannot be closed using the task manager. A shutdown won't do anything. During the last month I had this problem about three times and the only way I could close it was to long press the power button of the computer until it was turned off "the bad way".

  


  Any ideas what to in such situations ?
  
Or even better : How to prevent those situations ?
What can the reason(s) be for the error ?
Do you understand the message ?

  


  When the computer is started again the next morining and I run the same .bat file again everything works fine. So the same error does not repeat and the video is edited nicely !

  


  Edit : Now, about one week after posting this question the problem occurred many more times ! It is very annoying. I guess it has to do with the external hard drive connected by USB. Sometimes it randomly interrupts the connection ! That might be the reason for the behavior. Whatever its causing the error, I want to learn a solution how to deal with this in future. I don't want to always push the reset button of my computer. I want a proper way to be able to shut it down.

  


• Users Flow for Piwik : discover the most popular paths your users take through your website or app

  14 décembre 2016, par InnoCraft — Plugins

  Hi, this is Tom from InnoCraft. The company of the makers of Piwik.

  Do you know how your visitors navigate through your website or app ? Well, we thought we did, but it turned out we didn’t until we actually were able to visualize those paths over several steps in an easy to understand graph. We were really surprised by some paths our users took every day. We discovered new popular pages where we totally under-estimated their importance. We found that many users actually had a problem on our home page so they had to reload it and we improved some popular paths we didn’t expect users were going. Now these paths are much more straight-forward for our users.

  -> Read the rest of the story on the Users Flow Marketplace page.

  What does the new Users Flow report look like ?

  Here is below just a little preview of the Users Flow report. The plugin includes more reports and goodies !

  

  Where do I get Users Flow ?

  Users Flow is available on the Piwik Marketplace :

• Plex DVR File Rename on FFMPEG Encoding

  11 juillet 2021, par Brent Johnson

  I'm currently using a bash shell script to encode all of my Plex DVR recordings to H.264 using FFMPEG. I'm using this little for loop I found online to encode all of the files in a single directory :

  


  for i in *.ts;
    do echo "$i" && ffmpeg -i "$i" -vf yadif -c:v libx264 -preset veryslow -crf 22 -y "/mnt/d/Video/DVR Stash/Seinfeld/${i%.*}.mp4";
done


  


  This has served its purposes well but in the process I would like to rename the file to my preferred naming convention so that the original filename Seinfeld (1989) - S01E01 - Pilot.ts is renamed to Seinfeld S01 E01 Pilot.mp4 in the encoded file. While I am already using a regular expression to change the .ts extension to .mp4, but I'm no expert with regex, especially in the bash shell so any help would be appreciated.

  


  For anyone that's interested in my Plex setup, I'm using an old machine running Linux Mint as my dedicated DVR and actually accessing it over the network with my daily driver which is a gaming machine, so more processing power for video encodes. While that one is a Windows machine, I'm using the Ubuntu bash under WSL2 to run my script, as I prefer it over the Windows command prompt or Powershell (my day job is a web developer on a company issued Mac). So here's a sample of my code for anyone that might consider doing something similar.

  


  if [[ -d "/mnt/sambashare/Seinfeld (1989)" ]]
then
    cd "/mnt/sambashare/Seinfeld (1989)"
    echo "Seinfeld"
    for dir in */; do
        echo "$dir/"
        cd "$dir"
        for i in *.ts;
            do echo "$i" && ffmpeg -i "$i" -vf yadif -c:v libx264 -preset veryslow -crf 22 -y "/mnt/d/Video/DVR Stash/Seinfeld/${i%.*}.mp4";
        done
        cd ..
    done
fi


  


  While I've considered doing a for loop for all shows, for now I am doing each show like this individually as there are a few shows I have custom encoding settings for
