Wrong minor version in libavfilter/meson.build
The minor version in meson.build (85) here doesn't match version.h minor version (110) : https://gitlab.freedesktop.org/gstreamer/meson-ports/ffmpeg/-/blob/meson-4.4/libavfilter/meson.build#L2
Here is the version.h minor version : https://gitlab.freedesktop.org/gstreamer/meson-ports/ffmpeg/-/blob/meson-4.4/libavfilter/version.h#L33
This seems also to be the case with libavutil (56.51.100 instead of 56.70.100).
Note that I have found this when trying to apply a tier FFmpeg patch which uses LIBAVFILTER_VERSION_MINOR to check the version of FFmpeg.
