• ERROR : libvpx decoder version must be >=0.9.1 [closed]

  22 novembre 2013, par Baseem Najjar

  Heyo !
  I'm trying to install ffmpeg on my server using the following tutorial :
  https://ffmpeg.org/trac/ffmpeg/wiki/UbuntuCompilationGuideLucid
  When I reach the ffmpeg part and run the ./configure command it gives the following error :

  ERROR: libvpx decoder version must be >=0.9.1

  I must mention that my server has Ubunto 10.10 64bit
  I'm a total newbie in linux so please take it into consideration :)
  Thanks a lot !

  Following LordNeckBeard solution, I got the following error after the checkinstall :

  root@348588:~/libvpx# sudo checkinstall --pkgname=libvpx --pkgversion="$(date +%Y%m%d%H%M)-git" --backup=no--default --deldoc=yes
  
  
  
  checkinstall 1.6.2, Copyright 2009 Felipe Eduardo Sanchez Diaz Duran

  no--default is an invalid value for --backup
  
  
  
  Use --help or -h to get more information

• why I can't compile x264 or ffmpeg downloaded from git

  4 avril 2013, par Monjura Rumi

  It has been just a few days that I am using x264, ffmpeg and trying to take help from codes in git. I am always having some peculiar problem. It seems like no one or few people faced such problems. Here is one of those problems. If I download x264 or ffmpeg using git then I could not compile that source code. At first terminal will show ./configure: Permission denied. Then If I change permission of configure file using chmod 755 command then it will show ./configure: /bin/bash^M: bad interpreter: No such file or directory. To build x264 and ffmpeg I have followed this link https://github.com/lince/libffmpeg-c/wiki. My attempt to compile x264 has failed. Can you please tell me how can one use source code downloaded from git ?

• #/bin/sh in one line

  27 juillet 2012, par GoodGuyGreg

  I'm working on some Haskell project using FFmpeg. I need to batch create from a media folder with MP4 files and create screenshots from all of them. I got the code and am using it on a terminal in Unix. It works, but how do I make it in one line to be executed in system "xxxx" in Haskell ?

  If not using several system"xx"...

  #/bin/sh
  
  for i in $(ls *.mp4)
  
  do
  
      ffmpeg -i $i -vframes 7 -y -ss 10 -s 150x150 -an -sameq -f image2 -r 1/5  $i%1d.jpg
  
  done

  I tried :

  import System.Cmd
  
  function = do{system "#/bin/sh";
  
  system "for i in $(ls *.mp4)";
  
  system "do";
  
  system "ffmpeg -i $i -vframes 7 -y -ss 10 -s 150x150 -an -sameq -f image2 -r 1/5  $i%1d.jpg";
  
  system "done";}

  but it gives a error :

  -vframes: No such file or directory
  
  /bin/sh: Syntax error: "done" unexpected
