Error: keyframe filtering mode 2 currently only works when using mkvmerge as the concat method #762

This error occurs when using "--enable-keyframe-filtering=2" as a parameter.

This is expected behavior, ffmpeg cannot handle kf2, mkvmerge can. Thus, this is not an issue of av1an but a feature request for the ffmpeg devs if you wish for ffmpeg to support it.

Due to the efforts of devs in the AV1 Community discord, kf2 is no longer necessary for its efficiency benefits and kf1 is now the standard of choice when using the lavish fork of aom. kf1 also has the benefit of maximum playback compatibility

Ah I see, thank you!
