• Find the files that have been modified in last 24 Hours only once(skip if its modified more than once) [duplicate]

  4 janvier 2020, par Vijay Chandra

  This question already has an answer here :

  • How to find the number of times particular file has been modified in given time range [closed]
    
    2 answers
    

  Im using this command to get all modified files in the last 24 hours in ubuntu,
  find -type f -name "*.mp4" -mtime -1 -printf "%f\n"
  How can i modify this to detect same file only once which means if same file is modified more than 1 time in the last 24 hours,It shouldnt consider this file,It should skip the file,Is there anyway to do this ?
  I need this to create a watermarking script which will find the latest files within 24hours and save the list to a txt file and with the help of this text file,I use ffmpeg to watermark the videos and move them to original location.If i do this,the find command is considering the new updated video as modified file and adding watermark again and again,The process isnt getting stopped,Someone please help to fix this.

  My code is attached below :

  #!/bin/bash find -type f -name "*.mp4" -mtime -1 -printf "%f\n" >> /home/domain.com/public_html/admin_panel/public_html/uploads/mp4/temp/file.txt filename='/home/domain.com/public_html/admin_panel/public_html/uploads/mp4/temp/file.txt' all_lines=`cat $filename` for item in $all_lines; do  cp $item /home/domain.com/public_html/admin_panel/public_html/uploads/mp4/temp ffmpeg -i $item -i watermark.png -filter_complex "[1][0]scale2ref=w='iw*30/100':h='ow/mdar'[wm][vid];[vid][wm]overlay=(main_w-overlay_w):(main_h-overlay_h)"
  
  -y /home/domain.com/public_html/admin_panel/public_html/uploads/mp4/temp/$item 
  
  done

• Anyway to get current playtime of a song ?

  2 décembre 2019, par Blue Lightning

  So this is the basic voice that I’m currently using to play music through my bot. I’m streaming the audio (using the stream async function) opposed to downloading it local. Anyway I can get the current playtime of the song that is being played ?

  So whenever someone plays a song, they can, whenever they want, see how much of the song they played through already.
