Replying to michael:
Fixed in dd1b4ed6d98f1f4dd566a28ec5ade00712f9c27c and 7727f76230e60c9da881a51e53f6d34f249fa2fd and 38025e6898ef7caa076ff20daf4fc9f27269e4df and a4f9bb228bb34f0cfa4b55b207c19604b1e36818
Thanks for implementing this! The only problem is that the output should be in negative.
ffmpeg -i CCITT_FAX3/4_unc.tif -vf negate out.bmp <- correct output
