• How to install ffmpeg using xampp

  28 avril 2014, par Paul Ledger

  I am trying to install ffmpeg onto my localhost server. I have followed countless blogs and tutorials online form other people who are stuck with this same problem. I follow everything to the letter.

  1. Unzip the file
  2. Copy php_ffmpeg.exe to ext folder in php
  3. copy the rest to system 32

  As it says however when I do this I get this error when I start apache.

  

  Fair play but it is in the folder

  

  I also get this error as well :

  

  And Again, here it is :
  

  I have added the extention to my php.ini file

  extension=php_ffmpeg.dll

  The first time I go this to work I placed the ffmpeg.exe file onto my local host server and ran commands like this :

  $cmd = "$ffmpegpath -i $input -an -ss $sec -s $size $output";
  
  shell_exec($cmd);

  This works fine on my computer but not on an actual server. Could somebody offer some advice or guidene on where I have one wrong installing the extension or why running the .exe file on a lunix server with shell_exec doesn’t work

• OpenCV no longer working after Homebrew install

  28 mars 2014, par Tom smith

  I have have been running OpenCV from QT creator on Mac OSX.
  I was having trouble getting VideoWriter to work so it was suggested I try installing ffmpeg with opencv.
  Using brew I executed this command

  brew install homebrew/science/opencv --with-ffmpeg 

  However, during this process I received the following error

  Warning: Could not link opencv. Unlinking...
  
  Error: The `brew link` step did not complete successfully
  
  The formula built, but is not symlinked into /usr/local
  
  You can try again using `brew link opencv'

  The "possible conflicting files were mostly from "/usr/local/include/opencv2/"

  I tried the command brew suggested but this gave me a permission denied warning so I found a fix to execute before the command, both of which are below.

  sudo chown -R `whoami` /usr/local
  
  brew link --overwrite opencv

  This appeared to execute correctly giving me the following response

  Linking /usr/local/Cellar/opencv/2.4.8.2... 251 symlinks created

  The problem is this now seems to have broken my working project. When I try to run the project now I get the following errors
  Unfortunately after trying to rebuild the project I cannot get the error below to show up in the terminal again but it said the following error, was expected in /usr/local/include but not found in the build directory (afraid I cannot be sure of the exact wording)

  dyld: lazy symbol binding failed:

  In QT creator however, when trying to build the project it says

  error: symbol(s) not found for architecture x86_64
  
  error: linker command failed with exit code 1 (use -v to see invocation)

  Any suggestions for a fix, and also how I can get VideoWriter to work with opencv on Mac OSX after I have my project working again ?
