I need to use ffmpeg with very large images (32768x16384). When I try to read such an image I get the error:
Picture size 32768x16384 is invalid
It it does not matter what operation I want to do on the image (like scaling, v360 cutout etc.) it already fails at the read-in stage. I tried JPG and PNG as input formats.
Full log with demonstration operation (scale 32k to 16k)
