• 12 ffmpeg xfade transitions : "option not found"

  17 juillet 2023, par nimda

  I'm running into a strange error where each of these following 12 of the 56 xfade transitions are throwing errors :

  


  

  • hlwind

  


  • hrwind

  


  • vuwind

  


  • vdwind

  


  • coverleft

  


  • coverright

  


  • coverup

  


  • coverdown

  


  • revealleft

  


  • revealright

  


  • revealup

  


  • revealdown

  


  


  I've tested all filter transitions with the following command, which is being generated by a nodeJS app with the fluent-ffmpeg library, and only the twelve listed above fail with the same error "option not found" :
