Speed pin doesn’t accept negative values for reversed playback, is there other way to play reversed video other than to render it?
vlc doesn’t support reverse playback, only a few decoder supporting it in fact (I think only quicktime actually).
Please also note if you go that route, make sure to also use codec with 1 keyframe every frame, otherwise that will hurt.
If one day I manage to clear a bit my never ending todo list, I’ll finally implement this hap reader properly, then reverse/seek and all this becomes trivial.
