In tile : RLE, ZIP1, ZIP16, PXR24 will work fine without modification, because they don't use s->xdelta (the datawindow width) PIZ, B44, B44A, use s->xdelta, so now, they will have some trouble for datawindow bigger than tile size in X. I will make a patch soon, for this. Can you send me your PIZ sample who make ffmpeg crash to check (with wetransfer or something similar) ?
