12 ffmpeg xfade transitions : "option not found"
17 juillet 2023, par nimdaI'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" :


ffmpeg -f lavfi -t 169
