GPL Filters

GPL Filters

Separate from the GPL-licensed encoders (x264/x265/xvidcore — see Licensing), FFmpeg itself ships several filters that are GPL-licensed at the source level, per the FFmpeg License. These are only available in the Full GPL tier (built with --enable-gpl):

• blackframe
• boxblur
• colormatrix
• cover_rect
• cropdetect
• delogo
• eq
• find_rect
• fspp
• histeq
• hqdn3d
• kerndeint
• lensfun
• mcdeint
• mpdecimate
• mptestsrc
• nnedi
• owdenoise
• perspective
• phase
• pp
• pp7
• pullup
• repeatfields
• sab
• signature
• smartblur
• spp
• stereo3d
• super2xsai
• tinterlace
• uspp
• vaguedenoiser

If a command using any of these fails with a "No such filter" error on the Free, Basic, or Full tier, that's why — switch to Full GPL (note: this changes your app's licensing obligations, see Licensing) or avoid the filter.
