Prior to this, the results were not saturated into the uchar/ushort range before being written. The characteristics of the Lanczos filter exposed this issue. In addition, the results were truncated rather than rounded, which resulted in checkerboard artifacts in solid color areas and were noticeable when using Lanczos with 8-bit input. Example: ffmpeg -init_hw_device cuda -f lavfi -i testsrc2=s=960x540,format=yuv420p \ -vf hwupload,scale_cuda=format=yuv420p:w=-2:h=720:interp_algo=lanczos \ -c:v h264_nvenc -qp:v 20 -t 1 <OUTPUT> Fix #20784 Signed-off-by: nyanmisaka <nst799610810@gmail.com> |
