• One video on top of the other with FFMPEG on Android [closed]

  29 avril 2020, par Jules Hummelink

  We are currently working on an app. The app needs to loop a mp4 file (with the black pixels as alpha) on top of the other clip. We made an openCV script that could do this but then found out that openCV on android can't open video files. Does anyone know a ffmpeg command that can do this ? Or another way to do this on android ?

  



  Thx a lot,
Jules

  



  EDIT
A chromakey won't work because the result looks really bad :
