gpu: ipu-v3: image-convert: fix output seam valid interval (82c3e948) · Commits · 戴 / test

This fixes a failure to determine any seam if the output size is exactly 1024 multiplied by the number of tiles in a given direction. In that case an empty interval out_start == out_end is being passed to find_best_seam, which looks for a seam out_start <= x < out_end. Also reduce the interval for all but the left column / top row, to avoid returning position 0 as best fit. Signed-off-by:
