  I told my server to upgrade to latest version of ffmpeg and they told me they did and I have the latest version that is 2.2.1 .
  I test several codes to convert a video to x264 , here is the one ;

  passthru("$ffmpegpath -i aatest/a.AVI -c:v libx264 -c:a libfaac -preset veryslow -qp 0 aatest/output.mp4 2>&1");

• FFMpeg Concat Filter - Setting start position for file

  9 avril 2014, par Joyce Babu

  I want to concat two video files using the concat filter. The first file has to be included fully, whereas the second video must be included from the 10th second. Do I need to first create an intermediate file starting from the 10th second, or can I do it in one step ?

  The command I am using is

  /usr/local/bin/ffmpeg -i intro.mp4 -i input.mp4 -filter_complex '[0:v] scale=720:576 [in1]; [1:v] scale=720:576 [in2]; [in1][in2] concat [v]; [0:a][1:a] concat=v=0:a=1 [a]' -map '[v]' -map '[a]' output.mp4

  I tried specifying -ss after -i input.mp4, but it is applied on the final output file.

  iMac:files joyce$ /usr/local/bin/ffmpeg -i intro.mp4 -i input.mp4 -filter_complex '[0:v] scale=720:576 [in1]; [1:v] scale=720:576 [in2]; [in1][in2] concat [v]; [0:a][1:a] concat=v=0:a=1 [a]' -map '[v]' -map '[a]' output.mp4
