The comments of the ticket also provide a solution.

You could also use `ffprobe -i <input_video> -debug 1`. There’s some documentation on that at https://trac.ffmpeg.org/wiki/Encode/FFV1 <https://trac.ffmpeg.org/wiki/Encode/FFV1>.

Is it after https://git.ffmpeg.org/gitweb/ffmpeg.git/commit/abe76b851c05eea8743f6c899cbe5f7409b0f301 <https://git.ffmpeg.org/gitweb/ffmpeg.git/commit/abe76b851c05eea8743f6c899cbe5f7409b0f301> ?

Or if you run `ffmpeg -h encoder=ffv1` do you see the -slicecrc option?
