• Using bash to cycle through files in directory then create sub-directory based on file name

  8 décembre 2018, par Rick T

  What I’m trying to do is use bash to

  1) cycle through files in a directory 
  
  2) then create a sub-directory based on the file names 
  
  3) then split mp3 files using ffmpeg in 3 second increments.

  I can get the sub-directories created and the ffmpeg code splits the files up using the correct names. The issue I seem to be having is the loop. It creates the split-chirp directory and all it’s files but it doesn’t process the pink.mp3 file. See image below of the starting directory
  

  See image of ending directory
  

  It doesn’t create the split-pink directory and all the files (I know it’s a looping problem just can’t figure out why)

  I run the code using the command bash mp3spl.sh *.mp3

  Code below

  #!/bin/bash
  
  currentdir=$(pwd) #get current directory
  
  
  
  for f in $currentdir/*.mp3
  
  do
  
  
  
  fn=`echo "$1" | cut -d'.' -f1` #get just the filename no extension
  
  splitdirname="$currentdir/split-$fn"  #sub directory with correct names 
  
  mkdir -p "$splitdirname" #make split directory
  
  echo "Processing $f"
  
  ffmpeg -i "$1" 2> tmp.txt
  
  
  
      ffmpeg -i "$1" -f segment -segment_time 3 -ar 22050 -ac 1 "$splitdirname/$fn-%03d.mp3"
  
  
  
  #rm tmp.txt
  
  
  
  done

• FFMpeg : Take Certain Amount of Screenshots Between X and X ?

  10 janvier 2019, par user1445975

  Is there any way to get ffmpeg to take X number of screenshots between X time and X time ? The way I’m doing my command line code now is like this :

  ffmpeg -ss 79 -i 1.avi -r 1/2.15 -f image2 1_%%05d.jpg

  This method only starts taking screenshots starting at 79 seconds, but I can’t figure out a way to set an ending time (before the video ends).

  Also, I will be displaying these video screenshots on a website and want there to be the same amount of screenshots per video file for consistency purposes. Is there a way to set how many screenshots I want from a video ? As in, ffmpeg figures out how much time is between the two points I specify, then figures out how often to take a screenshot based on how many I want total from a video ?

• Range selector for Video trimming android

  28 février 2019, par VoidMain

  I am working on a project in which I have to trim a video. But first the user needs to select the video for trimming I have done a little digging around and have failed to find a suitable library. I need to implement just the UI that would let the user select the starting and ending point of the trim.

  (I need just the UI the data will be taken from that UI will be used in trimming the video using FFmpeg-android which is working properly)

  A library similar to this iOS layout would do the trick.

  Please, do let me know if you have any ideas ? or a better solution for it.

  Any help would be appreciated.
  Thanks
