GPL Licensed Filters

FFmpegKitNext builds FFmpeg under the LGPL by default. The filters below are GPL parts of the bundled FFmpeg source and require a GPL-enabled build.

Filters from GPL External Libraries

These filters are not standalone GPL source files in FFmpeg, but they require GPL external-library support in FFmpegKitNext.

Filter	Required library option
rubberband	rubberband
vidstabdetect	libvidstab
vidstabtransform	libvidstab

Notes:

• GPL filters and GPL external libraries require --enable-gpl.
• Linux system-library builds use the matching linux-* options for GPL system libraries, such as linux-libvidstab and linux-rubberband.
• pp is not listed here because it is not listed as a GPL filter in the bundled FFmpeg source.
