• 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

• ffmpeg filters image processing

  15 décembre 2017, par Ja_cpp

  ffmpeg is applying some filters to the images before constructing the video. Is there any way to know those filters ?

  I’m using this command (so every parameters are kept by default) :

  ffmpeg -framerate 12 -i frame%02d.jpg out.mp4

  Example of one frame :

  Image file :

  

  From the video :
  

  I’m working on image processing with c++ and I’m interested in the way ffmpeg filtering the images

  EDIT

  When I launch the command line, that what I get in the terminal :

  ffmpeg -framerate 5 -i frame%02d.jpg output.mp4
