• Composition on ffmpeg does not match sizes

  24 mai 2016, par Dbugger

  I am trying to take 3 videos and an image, and make a composition of 10 seconds roughly like this :

  

  This is the command I got so far. (I formatted it a little, so that is more readable)

  ffmpeg

  On the first 3 filters, I try to fill/crop the videos, to match 512x288
  On the next filters crop/fill the image to 640x874
  on the next 2 filtes, I add some padding to the top and middle video, of 5 pixels.

  The total height of the left column should be 288*3 + 5*2 = 874

  But when I run this command I get this error :

  Input 1 height 874 does not match input 0 height 872.

  Where did those 2 pixels go ? If instead of videos on the left, I use images, it works alright. Only with some videos, it seems to destroy those extra 2 pixels somehow.

  What is going on ? How could I fix it ?

  Windows : Ensure FreeLibrary() calls match LoadLibrary() calls
  The function get_utf8_argv() was calling LoadLibrary to load msvcrt.dll
  
  but wasn’t calling FreeLibrary() if GetProcAddress() fails.
