Hi, i noticed that the delogo filter alter the output images color. Not just the region i want to alter, the whole images.
Here is how i tested it: Sample 1: ffmpeg -i test.mp4 -r 1 -vf 'delogo=x=214:y=192:w=273:h=98:band=1' test2/%03d.png http://wstaw.org/m/2014/08/25/001_1.png Sample 2: ffmpeg -i test.mp4 -r 1 test2/%03d.png http://wstaw.org/m/2014/08/25/001.png You can compare the same image from both samples like this: compare -metric PSNR test/001.png test2/001.png difference.png http://wstaw.org/m/2014/08/25/difference.png but you can see it without that, one images has is slighty greyish tint. Here ist he sample video i tested with: http://www.fileswap.com/dl/vf8t4Sjm0S/ I hope someone can help me.
