• 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

  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.

  Bueno como mis presentimientos eran ciertos. El problema es de la versión del spip 3.0.20. Me atrase a la versión 3.0.17 y anda bien el el GD2.

• ffmpeg : Resource temporarily unavailable

  26 octobre 2015, par Cabbage soup

  I’m trying to run ffmpeg on a linux server (info from uname -a) :

  Linux comp32 2.6.32-279.14.1.el6.x86_64 #1 SMP Tue Nov 6 11:21:14 CST 2012 x86_64 x86_64 x86_64 GNU/Linux

  ffmpeg (together with the required encoders and decoders) compiles successfully on the system, but when I try to perform a basic operation like the following : ffmpeg -v debug -i example.m4v image%d.jpg, I get a slightly cryptic error message :

  I also tried using a static build off ffmpeg, downloaded from here, but got the same resource temporarily unavailable message. Any ideas on how I might be able to fix this ?
