[FFmpeg-devel] [PATCH] avfilter: add skipblend filter

Attached a patch which adds a "skipblend" filter, which I've been using for a while. My hope is that an ffmpeg developer here can merge it. The filter is similar to the framestep filter, but additionally blends frames together at each step, for a motion blur effect. The number of frames that are

[FFmpeg-devel] [PATCH] fix some filter dependencies

Currently, ffmpeg builds with --disable-avcodec --disable-avformat --enable-avfilter result in a broken avfilter library due to a few filters that require avcodec or avformat are mistakenly compiled in. For example, see:
