[FFmpeg-devel] [PATCH] lavfi/mp: remove some pp filters.

[Clément Bœsch]

 - fspp seems to be a 1d version of spp; users seem to prefer spp
   (denouncement: michaelni, iive, microchip).
 - pp7 is a special version of spp, it might be worth including it in
   the native spp at some point.
 - uspp is a slow and less effective spp

The use-cases of such filters being relatively limited nowadays, it
doesn't seem worth keeping all those pp filters; spp and all the
libpostproc filters should be enough, and optimizations can be added
later if that's really necessary.
