• Unable to 'make' android ndk project - build fails : [build-openh264-x86] Error 2

  18 décembre 2015, par NoobNinja

  I’ve attempted these two fixes I’ve found while researching the issue :

  android update project  --23 --/Users/ajswann/Downloads/android-sdk-macosx 
  
  
  
  make OS=android NDKROOT=/Users/ajswann/Downloads/android-sdk-macosx TARGET=android-19 ARCH=x86 clean

  ...however neither seems to resolve the issue.

  Any input/suggestions are appreciated.

  P.S.

  I’m running OSX - could this be an issue with attempting to run an x86 architecture on a 64 bit machine ?

• FFMPEG : Creating a video, which has the maximum value per pixel of n-input videos

  13 décembre 2017, par LighthouseZGZ

  Imagine a collection of short videos, each one showing a shooting star.

  I would like to get a composite video of all shooting stars. Not in sequence, at the same time. The (x,y) pixel of the nth frame in the output video should have the maximum value for that (x,y) pixel of the same frame in all the videos.

  I know how to do that using images and imagemagick :

  magick *.bmp -evaluate-sequence max output.bmp

  I need something similar for video. Frame by frame.

  Any help would be appreciated. Thanks.
