Port mpv's error diffusion algorithm
With mpv's libplacebo
-based gpu_next
VO maturing and on the track to replace the legacy gpu
VO, it will be great to port the error diffusion algorithm to avoid any feature loss.
- The error diffusion implementation in mpv is fairly stand-alone. I expect the effort to port it to be minimal.
- With
vf_libplacebo
merged into ffmpeg now, I see real benefits of a GPU based error diffusion filter. There is no alternatives AFAICT.
