• Bash script to convert imgs in subfolders to video (using ffmpeg and Ubuntu)

  2 novembre 2015, par mcExchange

  I’m trying to convert all files in folders given by

   allFolders.txt
  
  > head folderNames.txt
  
  0001 
  
  0002 
  
  0003 
  
  0004 
  
  0005 
  
  ...

  to a video using ffmpeg

  ffmpeg version 2.2.3 Copyright (c) 2000-2014 the FFmpeg developers  built on Apr 20 2015 13:38:52 with gcc 4.8 (Ubuntu 4.8.2-19ubuntu1)
  
  configuration: --prefix=/home/myUsername/usr/local --enable-nonfree --enable-gpl --enable-pic --enable-shared --enable-libx264 --disable-vaapi

  According to some answers here on stackoverflow I wrote the following bash script :

  #!/bin/bash
  
  while read p; do
  
      cd "$p"
  
      ffmpeg -f concat -i "allImgNames.txt" -framerate 30 -c:v libx264 -profile:v high -crf 20 -pix_fmt yuv420p output.mp4
  
      cd -
  
  done < folderNames.txt

  where allImgNames.txt is a text file containing all the image names.

  The strange thing is that it works for a few videos but for the rest of the filelist it fails saying allImgNames.txt: No such file or directory, which is not true. I checked all paths several times. Also I can execute the ffmpeg ... command above manually without problems.
  I don’t know what I’m doing wrong. All file / folder names are normal (no special characters). Maybe I don’t understand enough about bash or ffmpeg.

• Use ffmpeg to create a video/audio file of X length, and then add audio/video sequences from multiple other files

  9 novembre 2015, par robert paré

  I have several mp4 files that contain video and audio content ("base" videos)

  I have a length value (recordingLength) in which the output video should be (let’s say 3600 seconds).

  I have to take clips from the "base" videos, at specific times and of specific duration.

  What I’m trying, is first creating a blank file with the total length (recordingLength) of 3600 seconds. I do it like so :

  ffmpeg -f lavfi -i anullsrc -t 3600 -c:a libfdk_aac ./output.mp4

  Then let’s say I have 5 base videos each lasting a couple of minutes, and I need to take a short segment from each of them (20-30 seconds) at a specific time, and then merge that segment at a specific time in the blank file created above. I tried playing around with -itsoffset {seconds} -t {seconds} but I’m still really just playing around trying to get my head around all the options.
